Definitions
- the disclosed matter generally relates to compositions and methods for reducing or preventing microorganism growth or survival. More specifically, the disclosed matter relates to compositions and methods for treating meat and poultry to eliminate pathogenic microorganisms.
- BACKGROUND Prevention of food-borne illness has been of paramount concern for the food industry, the public, and the regulatory agencies.
- the Centers for Disease Control and Prevention (CDC) conducted an evaluation to better quantify the impact of food-borne diseases on health in the U.S. (Mead, et al., Food-Related Illness and Death in the United States, Centers for Disease Control and Prevention, Atlanta, Georgia, USA, 2003).
- the report estimated that food-borne diseases cause approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the U.S. each year.
- Known pathogens account for an estimated 14 million illnesses, 60,000 hospitalizations, and 1,800 deaths.
- Salmonella is one of the more common intestinal infections with potentially fatal consequences.
- the CDC reports that every year approximately 40,000 cases of salmonellosis are reported in the U.S. Because many milder cases are not diagnosed or reported, the actual number of infections is likely much higher. Salmonellosis is more common in warmer months than during the winter months. And the most likely to have severe infections are young children, the elderly, and the immuno-compromised. It is estimated that approximately 600 persons die each year with acute salmonellosis.
- Salmonella and many other microorganisms can adhere to poultry, meat, and other food tissues, making removal of the microorganisms difficult with rinsing alone. Consequently, treatments including irradiation, chemical treatment, and physical processing have been used to address the problem of microorganism contamination of food. For example, trisodium phosphate has been used in poultry processing to eliminate Salmonella typhimurium. However, studies have provided conflicting results on efficacy of trisodium phosphate against treating Salmonella.
- U.S. Patent No. 5,366,983 discloses a composition containing an aqueous solution of a quaternary ammonium compound ("QAC").
- QACs including alkyl pyridinium halides (such as cetylpyridinium chloride (“CPC”) and cetylpyridinium bromide (“CPB”)) were effective in removing Salmonella but not other types of microorganisms.
- CPC cetylpyridinium chloride
- CB cetylpyridinium bromide
- treatment with CPC requires contacting the meat or poultry with large quantities of CPC for long periods of time. This requires costly downstream processing steps to remove the CPC. Typically, this is done by recapturing the product as it is sprayed and hauled out, similar to toxic waste.
- U.S. Patent No. 5,855,940 also discloses a composition containing a QAC for inhibiting attachment of and removing pathogenic toxin-producing Escherichia contamination.
- This patent discloses a composition containing QAC selected from the group consisting of alkyl pyridinium, tetraalkylammonium, and alkylalicyclic ammonium salts in an aqueous solution.
- Treatment methods include treatment with a chlorine solution or with a solution of tri-sodium phosphate.
- Chlorine solutions have been found ineffective in eliminating all of the pathogenic microorganisms.
- the efficacy of the chloride is only as good as the mole concentration of the chloride ion.
- the concentration of chloride ion can decrease rapidly due to the ion interacting with, for example, nascent oxygen.
- Tri-sodium phosphate has been used during the reprocessing stage where the inside and outside of the poultry is sanitized. This process, however, requires filtering the reprocessor's water before disposal in order to remove tri-sodium phosphate.
- antimicrobial compositions that are used, while effective on some surfaces, can not be used on food surfaces due to their toxicity.
- presently there are no known effective antimicrobial compositions that are effective against a broad range of microorganisms and can be safely be used on food surfaces. Accordingly, there is a need for antimicrobial compositions and methods for treating contaminated food such as poultry and meat to eliminate a broad range of microorganisms. Further there is also a need for antimicrobial compositions that can be effectively be used on other surfaces, such as floors, coolers, tables, trays, and the like. The antimicrobial compositions and methods disclosed herein meet these and other needs.
- compositions and methods for preparing and using such compositions in one aspect, relates to compositions and methods for preparing and using such compositions, hi another example, disclosed herein are antimicrobial compositions and methods for using such compositions to reduce, prevent, or eliminate a microorganism, such as a food-borne microorganism on poultry and meat.

- Ranges can be expressed herein as from “about” one particular value, and/or to "about” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about,” it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10" is also disclosed.

- reduce or other forms of the word, such as “reducing” or “reduction,” is meant lowering of an event or characteristic (e.g. , microorganism growth or survival). It is understood that this is typically in relation to some standard or expected value, in other words it is relative, but that it is not always necessary for the standard or relative value to be referred to. For example, “reduces the population of bacteria” means lowering the amount of bacteria relative to a standard or a control.
- prevent or other forms of the word, such as “preventing” or “prevention,” is meant to stop a particular event or characteristic, to stabilize or delay the development or progression of a particular event or characteristic, or to minimize the chances that a particular event or characteristic will occur.

- something could be prevented but not reduced, but something that is prevented could also be reduced.
- reduce or prevent is also expressly disclosed.
- treat or other forms of the word, such as “treated” or “treatment,” is meant to administer a composition or to perform a method in order to reduce, prevent, inhibit, break-down, or eliminate a particular characteristic or event (e.g., microorganism growth or survival).
- antiimicrobial is meant the ability to treat (e.g. , reduce, prevent, inhibit, break-down, or eliminate) microorganism growth or survival at any concentration.

- the disclosed antimicrobial compositions can, in one aspect, be used to treat a microorganism on a surface (e.g., poultry, meat, raisin, litter, or food contact surfaces, food processing equipment surfaces) by contacting the surface with an effective amount of the disclosed antimicrobial composition.
- an effective amount of a composition as provided herein is meant an amount of a composition sufficient to provide the desired result, e.g., reduction or prevention of microorganism growth or survival.
- the exact amount required will vary from use to use, depending on the type of surface to be contacted, the type of microorganism to be treated, the size of the processing facilities (e.g., the volume of the scalder or chiller), the mode of application (e.g., electrospray or dipping), the particular compositions being used, and the like. Thus, it is not possible to specify an exact "effective amount.” However, an appropriate effective amount can be determined by one of ordinary skill in the art using only routine experimentation.

- FIG. 1 is a flow chart showing the processing steps taken during poultry processing.
- conveyor 100 is used to transport the poultry through various steps of the processing plant.
- live birds brought in are loaded onto an automated conveyor belt at step 105.
- live birds are exposed to electrical current; this stage is also known as stunning.
- the birds are stunned when their heads (primarily the comb) contact a saline solution in the bottom of the stunner through which an electrical current is surging.
- This jolt of electricity is not severe enough to permanently damage or kill the bird, but immobilize the bird and allow the body of the bird to become relaxed enough to allow for automated killing.
- the birds With the birds still hanging upside down, and necks outstretched due to stunning, the birds are exsanguinated by an automated circular blade at step 115 of the process.
- the bird is submerged in a large tank of circulating hot water (about 128 to about 134 °F; about 53 to about 57 0 C) for about 2 minutes to loosen the feathers.
- This process is called "scalding.”
- the feathers and skin of the bird come out of the scalding process saturated with water. This process is particularly susceptible to bacterial cross-contamination since the birds are immersed in a common bath.
- the picking process 125, and head removal 130 are performed.
- the birds are then dropped off of the aerial conveyor system at hock cutter step 135.
- the U.S. Department of Agriculture (“USDA”) requires one quart of fresh water or recycled water to be added for each bird that enters the scald tank; thus, there is a continuous overflow of water from the scald tank, hi one aspect (see Figure 2), the scald tank is replenished with the rinsate from the spray system downstream with the antimicrobial solution at slightly less than full strength (e.g., 502 ppm) in order to decrease the cross-contamination of pathogenic bacteria in the scald tank.
- the scald tank can be treated after it is initially filled with fresh water with the disclosed compositions at full strength. This can assure treatment of birds that pass through the scald tank, prior to the spray system rinsate recycle process.
- step 135 preen gland is removed and at step 140 a venting machine cut around the vent or the anus of the bird, removing about two inches of any possible remaining fecal mater from the colon.
- a chlorinated water spray is utilized on this machine to keep any possible fecal material from contaminating the outside skin of the bird.
- the next machine is the eviscerator (step 145). It uses a spoon- like device to pull the internal organs out of the body cavity. This machine typically has a chlorinated water spray to keep any intestinal contents from coming into contact with the outside surface of the bird.
- This machine does not entirely remove the guts or "viscera” from the carcass, but gently drapes the "viscera package” onto the back of the bird where it can be viewed by USDA inspection personnel for possible diseases. After the USDA inspector has viewed the entire bird, including the viscera package, the viscera are removed from the carcass and fall into the same offal trough which has already received the preen gland, head, and neck.
- the gizzard, heart, and liver are harvested from the birds for human consumption (step 150).
- the viscera are dropped into the trough or "offal line" (step 155)
- the lungs are suctioned out of the body cavity and then enter the offal line.
- This fully eviscerated carcass hanging on the shackle line by the legs is commonly referred to as the WOG (whole carcass without giblets).
- the next two steps are cropper 160 and the neck breaker 165.
- step 170 After USDA inspection and viscera removal, the inside and outside of the carcass are thoroughly washed (step 170). While the carcasses are still moving on an overhead conveyor system, they pass through at least one "inside/outside bird washer.”
- This system is comprised of a stainless steel cabinet that is designed for automated washing of carcasses. Several gallons of water are used to clean each individual carcass, inside and out. All of the water used in these wash cabinets is directed to the offal line.
- the spent wash water water which is continually used to rinse off the evisceration machinery, water from hand and knife washing stations, and fresh water as needed, is utilized to move the inedible material through the offal troughs and is deposited into the waste stream.
- FIG. 2 is a flow chart showing a processing method according to one aspect of the subject matter disclosed herein.
- the antimicrobial composition disclosed herein can be applied to the poultry at stage 170. This application is typically done by spraying the suspended poultry.
- the spraying process can include the outside as well as the insides of the poultry.
- a predetermined amount of the antimicrobial composition is sprayed on the carcass.
- the runoffs are then collected and supplied to the scalder for reuse; thus, the antimicrobial composition along with fresh water is provided counter-current to the direction of the carcass. Thereafter, they may be reused in the scalder or added to the waste stream.
- additional antimicrobial composition can be added to the recycled stream 200 in order to bring the concentration to the desired level. While the concentration may be varied depending on the application, it has been found that a concentration of about 200 to about 600 parts per million (ppm) of the disclosed compositions to water can be effective.
- the process includes a first exposure of the poultry to the disclosed antimicrobial composition in the scalder (120).
- Filtered rinse-water from the antimicrobial spray positioned just prior to the chiller can be added to the fresh water entering the scalder at a concentration of about 450 to about 600 ppm (except for start-up where the initial scald tank water can be activated with the disclosed antimicrobial composition at full strength).
- This water can then pass over the carcasses and exit the scalder at the overflow (where carcasses enter the scalder).
- the carcasses can be exposed to a maximum of about 450 to about 600 ppm of the disclosed antimicrobial composition.
- the carcasses can then continue down the processing line and through evisceration, cropping, and inside/outside bird washing, and finally pass through the spray cabinet, where a desired concentration of the disclosed antimicrobial composition can be applied again.
- the birds can then pass through the spray cabinet at normal line speed for application of the disclosed antimicrobial composition (e.g., about 0.2 gram of the antimicrobial solution per pound of carcass).
- Testing conducted by an independent laboratory showed that less than about 30 ppm of the antimicrobial composition disclosed herein remains on the carcass after both exposure points. That is, the majority of the disclosed antimicrobial composition drains out of the cabinet, is filtered, goes into the scalder, passes by the carcasses in the scalder and is sent to the waste stream. Material balance calculations demonstrate that about 99.9% of the disclosed antimicrobial composition will be sent to the waste stream.
- a drip tray can be included as part of the application system. As the birds exit the spray cabinet on their way to the chiller tank, they can pass over this drip tray, which collects any antimicrobial composition containing fluid that drips from the wet carcasses.
- This tray can extend for the distance covered by the carcasses in the first minute after they exit the spray cabinet, or typically about one-half the distance to the chiller.
- the liquid that drips into this tray can be combined with the fluid that drains from the antimicrobial spray cabinet and can be recycled back to the scalder. For the remainder of the distance to the chiller (i. e. , the second minute of travel time from the spray cabinet), any liquid that drips from the carcasses can go into the plant's existing floor offal collection system and ultimately will be collected as part of the offal.
- the carcasses can move via the overhead line to the chilling phase of the process. They drop automatically from the shackle line into a huge tank of water called the pre-chiller.
- This tank of water is typically held at about 55 °F (about 13 0 C) and the carcasses remain in the pre-chiller for about 15 minutes. During this time, the carcasses absorb about 4 to about 5 % added moisture.
- the water in the pre-chiller can be actively aerated to aid in water movement for increased chilling potential and water absorption.
- This aeration process combined with the large amount of fat that is present in the pre-chill water, forms a flocculent material that floats on the top of the chill water. This material, typically called “chiller skimmings,” is continuously removed from the pre-chiller water and diverted to the offal trough. From the pre-chiller tank, the carcasses move into the chiller tank (shown as step
- This tank is larger and colder than the pre-chiller, usually about 32 to about 34 °F (about 0 to about 1 °C).
- the carcasses stay in this tank for about 45 minutes, increasing their moisture content by an additional about 3 to about 4 % in the chiller.
- USDA allows poultry carcasses to gain a total of 8 % added moisture.
- this material is diverted to the offal trough.
- the carcasses are rehung on a different shackle line for transport to other areas of the plant. They may move to a whole carcass packaging station (step 185), to cut-up or de-boning, or they may be shipped to a different plant for further processing and cooking (step 190).
- the waste streams for antimicrobial solution in the poultry-processing environment are explained below.
- the great majority of the antimicrobial composition present in the spray solution can go to the scalder and, after passing through the scalder, can be conveyed to the waste stream and the offal.
- additional antimicrobial solution can be added to the rinsate collected from the spray cabinet, prior to introduction into the scalder.
- the maximum concentration of antimicrobial solution that can enter the environment as a result of its intended use will be limited to the amount that remains in the water or combined with organic material after passing through the scalder and any residual that may drip from carcasses after spraying or be rinsed from the carcasses during chilling. (This amount has been calculated to be about 502 ppm of the antimicrobial solution residue on the carcass).
- the antimicrobial solution can be applied by means of electrostatic coating.
- Use of an electrostatic sprayer can coat substantially all surfaces while requiring a minimal amount of material.
- Electrostatic spraying was developed over two decades ago and is used to apply pesticides to row crops. Law (Embedded-electrode electrostatic induction spray charging nozzle: theoretical and engineering design. Transact of the ASAE, 12:1096-1104, 1978, which is incorporated herein by reference for its teachings of electrostatic spraying) developed an electrostatic spray-charging system using air atomization, which has been used to achieve a 7-fold increase in spray deposition over conventional application methods.
- Herzog, et al demonstrated that insect control on cotton plants was equal to or better than conventional spray application using only one-half the amount of insecticide (Herzog, et al, Evaluation of an electrostatic spray application system for control of insect pests in cotton. J Econ Entomol, 6:637-640, 1983, which is incorporated herein by reference for its teachings of electrostatic spraying).
- Electrostatic spraying can be done by using air-atomizing induction charge nozzle which allows air and liquid to enter the nozzle separately. The air moves at a high speed through the nozzle and intersects the liquid at the nozzle tip, causing the formation of spray droplets.
- the droplets are generally about 30 to about 40 micrometers in diameter.
- the air pressure required is about 30 to about 40 PSI (about 2 to about 3 arm), while the liquid pressure is below about 15 PSI (about 1 arm).
- PSI about 2 to about 3 arm
- a rechargeable battery provides the electrical charge.
- the negatively charged droplets are propelled onto the target surfaces by the force of the turbulent air stream.
- the target surface e.g., the poultry
- the electrostatic charge on the spray droplets is negative.
- Positive electrical charges on the target surface pull the spray droplets to the tops, bottoms and sides of the surface providing 360 degree wrap-around coverage.
- any surface can be treated by the methods and compositions disclosed herein.
- the antimicrobial compositions disclosed herein have been found effective for applications other than treatment of poultry.
- the compositions disclosed herein have been found to be effective for treating poultry litter.
- the disclosed compositions can be added to the poultry litter as it is being created at the paper mill. It can be applied by electrostatic sprayers while on the paper processing lines. It can be applied to both sides of the paper prior to being chopped into the proper size for use as poultry litter.
- Another suitable application of the antimicrobial compositions disclosed herein is in production of raisins.
- grapes are laid out on a substrate in open air to expose the grapes to the ambient air for drying.
- the substrate also being exposed to the ambient air, can be contaminated with various airborne microorganisms.
- the substrate can contaminate the grapes. It has been found that treating the substrate with the disclosed composition can reduce, if not eliminate, the cross-contamination problem.
- the grapes lay on a paper substrate in the fields near the location of the vines until they dry into raisins. Mold and mildew begins to grow as moisture develops from changing dew point caused by weather.
- compositions disclosed herein can prevent the growth of the mold and mildew as it is used as a sealant in the paper.
- the disclosed compositions can be applied by spraying or dipping.
- Still other examples of uses for the disclosed antimicrobial compositions include treatment of other meat, fish, vegetable, and fruit.
- Additional surfaces that can be treated by the disclosed antimicrobial compositions include, but are not limited to, food processing equipment surfaces such as tanks, conveyors, floors, drains, coolers, freezers, equipment surfaces, walls, valves, belts, pipes, joints, crevasses, combinations thereof, and the like.
- the surfaces can be metal, for example, aluminum, steel, stainless steel, chrome, titanium, iron, alloys thereof, and the like.
- the surfaces can also be plastic, for example, polyolefins (e.g., polyethylene, polypropylene, polystyrene, poly(meth)acrylate, acrylonitrile, butadiene, ABS, acrylonitrile butadiene, etc.), polyester (e.g., polyethylene terephthalate, etc.), and polyamide (e.g., nylon), combinations thereof, and the like.
- the surfaces can also be brick, tile, ceramic, porcelain, wood, vinyl, linoleum, or carpet, combinations thereof, and the like.
- the surfaces can also, in other aspects, be food, for example, beef, poultry, pork, vegetables, fruits, seafood, combinations thereof, and the like.
- a surface e.g., poultry, food processing equipment surface, etc.
- an antimicrobial composition disclosed herein As compared with the conventional treatment methods, the disclosed compositions and methods have been found particularly advantageous in that the treatment process is faster and less caustic, hi addition, because a smaller amount of antibacterial composition is used, the process is more effective. Also, the disclosed antimicrobial compositions, in most cases, do not require complex equipment for their application, removal, recycling, or disposal. The following non-limiting examples, further illustrate advantages of the disclosed compositions and methods over conventional antimicrobial solutions and processes.
- Scalder water was collected from the overflow end (the entrance end) of a commercial poultry scalder. The water was autoclaved to eliminate all populations of bacteria and bacterial spores to avoid interference during the study. The autoclaved scalder water was evaluated chemically and compared to raw scalder water to ensure that the organic material in raw and autoclaved scalder water was similar.
- a test solution (interchangeably referred to in the examples as the antimicrobial composition) was prepared.
- the test solution contained cetylpyridinium chloride (7.5 parts by weight), alkyl dimethyl benzyl ammonium chloride (0.1 part by weight), trichloromelamine (0.1 part by weight), cetyl trimethyl ammonium chloride (0.1 part by weight), and water (92.2 parts by weight).
- a control solution was prepared by admixing cetylpyridinium chloride (7.5 parts by weight) and water (92.5 parts by weight). The same solutions were used in Examples 1-5.
- Test tubes were prepared by adding 9 mL of autoclaved (sterilized) scalder water to sterile polystyrene test tubes.
- One set was prepared as controls by adding 9 mL of autoclaved scalder water to tubes.
- Another set was prepared by adding 9 mL of autoclaved scalder water and 1 mL of the test solution as identified above.
- the pathogens were Salmonella typhimurium (“ST”), Listeria monocytogenes (“LM”), and Staphylococcus aureau (“SA”).
- the indicator was Escherichia coli (“EC") and the spoilage bacteria were Pseudomonas fluorscens (“PF”) and Shewanella putrefaciens (“SP”).
- microorganisms were grown overnight in Brian Heart infusion broth at 25°C for 24 hours. Each bacterium was exposed to each autoclaved scalder water- sanitizer combination for 2 minutes to mimic scalding. After exposure period, 1 mL of the suspension was placed into 9 mL of Brian Heart infusion broth and vortexed. One mL of this mixture was placed into the Bactometer module and bacterial growth was measured. The results are provided in Figures 3-6.
- Figure 4 is a graph that comparatively shows the reduction of bacterial colonies when exposed to a solution as disclosed herein and a solution of only cetylpyridinium chloride.

- Logio CFU Logio CFU
- Pseudomonas was also reduced to below 10 CFU/mL.
- Figure 5 is a graph showing the effect of the test solution as compared with the control solution. It can be seen from Figure 5 that over a period of 24 hours, Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, and Shewanella putrefaciens were completely eliminated while E. coli and Pseudomonas fluorscens were substantially reduced as compared with samples treated with the control solution.
- Figure 6 is a graph that comparatively shows the reduction of bacterial colonies when exposed to the test solution and the control solution.
- Figure 6 is similar to Figure 4 and shows that the colony forming units for all microorganisms where nearly eliminated upon treatment with the antimicrobial test solution.
- the antimicrobial solution was effective in eliminating all pathogenic, indicator, and spoilage bacteria tested in combination with scalder water applications. This data also indicates effectiveness of the test solution against very high concentrations of bacteria.
- Example 2 was conducted to measure the effects of antimicrobial solution at various concentrations on pathogenic, indicator and spoilage populations of bacteria associated with poultry. To this end, scalder water was collected from the overflow end (entrance end) of a commercial poultry scalder. The water was autoclaved to eliminate all populations of bacterial and bacterial spores to avoid interference during the study.
- the autoclaved scalder water was evaluated chemically and compared to raw scalder water to ensure that the organic material demand in raw and autoclaved scalder water were similar.
- the antimicrobial composition as in Example 1 was diluted with deionized water to ratios of about 1:100, 1:150, 1:200, 1:300, and 1:400 (composition to water).
- test tubes were prepared as controls by adding 9 mL of autoclaved (sterilized) scalder water to sterile polystyrene test tubes.
- One set was prepared as controls by adding 9 mL of autoclaved scalder water to test tubes.
- One set was prepared by adding 9 mL of autoclaved sclader water and 1 mL of each antimicrobial solution.
- the control solution as with the previous examples, comprised a cetylpyridinium chloride solution in water.
- the pathogens Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, the indicator Escherichia coli, and the spoilage bacteria Pseudomonas fluorescens and Shewanella putrefaciens were grown overnight in Brian Heart infusion broth at 25 °C for 24 hours. Each bacterium was exposed to each autoclaved scalder water-sanitized combination for 2 minutes to mimic scalding. After exposure period, 1 mL of the suspension was placed into 9 mL of the Brian Heart infusion broth and vortexed. One mL of this mixture was then placed into the Bactometer module well and bacterial growth was measured. The results are presented in Tables 1-7.
- the antimicrobial test solution disclosed above was found effective for eliminating populations of Salmonella, Pseudomonas, and Shewanella especially when used at concentrations of 1 : 150 or lower with scalder water applications.
- Table 1 is a graph that comparatively shows the effects antimicrobial solution at various concentrations as compared with a control solution. It can be seen from Table 1 that bacterial elimination is fairly high for a solution diluted to about 1 :100.
- Table 1 also shows the comparative effect of the test solution on Salmonella typhimurium as compared with a control solution. It can also be seen in Table 1 that the test solution diluted to about 1 :100 and 1 : 150 is very effective in reducing colony forming units.
- Table 1 The effect of Test Solution at various concentrations on Salmonella typhimurium
- Table 2 The effect of the antimicrobial solution on Listeria is shown in Table 2. It can be seen that the test solution according to the exemplary embodiment of the invention completely eliminated populations of Listeria and Staphylococcus at all concentrations, including solutions diluted with water to about 1 :400. Table 2 also shows that colony forming units were substantially eliminated by the antimicrobial solution at all concentrations.
- Table 2 The effect of Test Solution at various concentrations on Listeria monocytogenes
- Table 3 shows the comparative effects of various dilutions of the antimicrobial test solution on E. coli. As shown, the test solution was able to eliminate populations of E. coli at a dilution of about 1 : 100. At dilutions of about 1 : 150 (or lower) the test solution was able to eliminate all species tested with the exception of E. coli. Because E. coli is not a pathogen, it is not necessary that it be eliminated at the scalder. Instead, it can be eliminated later in the process. For this reason, a water dilution of about 1:150 has been found to be suitable for the scalder.
- Table 4 shows the comparative effects of the test solution at different concentration on Staphylococcus aureus.
- Table 4 The effect of Test Solution at various concentrations on Staphylococcus aureus
- Tables 5 and 6 comparatively show the effect of the test solution at different concentrations on Pseudomonas fluorescens and Shewanella putrefaciens.
- Table 7 comparatively shows the effect of the antimicrobial solution for eliminating colony forming units of Campylobacter jejuni at a dilution of 1 : 150.
- Table 7 The effect of Test Solution on Campylobacter jejuni at a dilution of 1:150
- the pathogens, Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, the indictor Escherichia coli, and the spoilage bacteria Pseudomonas Fluorescens and Shewanella putrefaciens were grown overnight in Brian Heart infusion broth at 25 °C for 24 hours.
- Five sterile TEFLONTM coupons were coated with 0.200 mL of each of the pathogens, the indicator or the spoilage species of bacteria (total of 30 coupons). The bacterial inocula were allowed to dry on the surface of the coupon for 4 hours. Each coupon was sprayed for 10 seconds (3 separate sprays) using a 1:100 concentration of the test solution. Each coupon was completely coated with 30 mL solution of this solution.
- each coupon was rinsed in 100 mL of sterile 1 % buffered peptone broth. One mL of this mixture was then placed into 9 mL of Brian Heart infusion broth and then 1 mL of this mixture was placed into the Bactometer module well for measuring bacterial growth.
- a control solution as disclosed above was prepared.
- an antimicrobial solution as disclosed herein was prepared for testing purposes.
- a sample of the coupons coated with the control solution and the balance was coated with the disclosed antimicrobial solution, hi both applications, electrostatic coating technique was used to adherently coat the entire surface of the coupon substrate.
- test solution was extremely effective in eliminating populations of Salmonella, Listeria, Staphylococcus, E. coli, and Pseudomonas on food-contact surfaces. This method is effective for treating and sanitizing food-contact surfaces before or after processing operation.
- Example 4
- test samples were processed in the same manner except the scalder water contained the antimicrobial solution and the sprayer contained the antimicrobial solution at a 1:150 dilution. The test was repeated three times (Reps. 1-3) and the Salmonella content of the samples were recorded.
- Figure 8 compares Salmonella content in control samples treated with water and test samples treated with diluted antimicrobial solution.
- Example 5 The procedure outlined about was repeated except that the samples were treated with E. coli and Coliform for establishing a baseline. Here, only one set of control and test samples were tested and the result is presented in Figure 9. Referring to Figure 9, it can be seen that E. coli and Coliform colony forming units were substantially reduced in test samples as compared with the control samples.
- Study I in-line reprocessing simulation
- Four broiler chicken carcasses were purchased from a local retail outlet. Two of the carcasses were rinsed with water for 3-5 seconds to simulate rinsing that takes place in the processing plant immediately prior to automated in-line reprocessing.
- the carcasses were then sprayed (to simulate delusion using an in-line sprayer) in an antimicrobial solution prepared according to Example 1 at a dilution of 150:1.
- the carcasses were allowed to remain for two minutes to simulate the drip time after in-line reprocessing and chilling.
- the carcasses were then placed into chilled water for 60 minutes to simulate chilling. During the chilling process, the carcasses were periodically stirred to simulate aeration. Additionally, the water was completely exchanged with fresh water after 30 minutes to simulate commercial situations.
- the carcasses where then cooked at 350 0 F (177 °C) for about 45 minutes.
- the carcasses were periodically stirred to simulate aeration. Additionally, the water was completely exchanged with fresh water after 30 minutes to simulate commercial situations. Carcasses were then cooked at 350 °F (177 °C) for 45 minutes. After cooking, the following steps were followed for each study. Fifty grams of skin was collected from each carcass. The skin samples were individually placed into a blender and 200 mL of deionized water was added. The skin was blended on high for 8 minutes. Three hundred mL of fresh deionized water was added to the blended mixture and blended for an additional 5 minutes. One hundred and fifty mL of the blended mixture was placed into a sample jar and sent to an independent laboratory for testing and evaluation.
- the combination of the various components in the antimicrobial composition work synergistically to bring about a more efficacious composition.
- a much smaller percentage of cetylpyridinium chloride comes into contact with the poultry while far superior bacterial elimination is obtained.
- the conventional composition of cetylpyridinium chloride is less effective against Gram-negative bacteria.
- the antimicrobial composition s disclosed herein have been found to have superior efficacy against Gram-negative bacteria.
- compositions were tested at several concentrations on E. coli, Salmonella typhimurium, and Listeria monocytogenes.
- stock solutions were prepared from various combinations of the components cetylpyridinium chloride (component “A”), alkyl dimethyl benzyl ammonium chloride (component “B”), cetyl trimethyl ammonium chloride (component “C”), and trichloromelamine (component “D”).
- the various stock solutions were then diluted with de-ionized water to form 1% v/v (i.e., 10,000 ppm) solutions, 0.0502% v/v (i.e., 502 ppm) solutions, and 0.0015% v/v (i.e., 15 ppm) solutions.
- a control solution of de-ionized water was also prepared.
- the various dilute solutions were then contacted to agar plates inoculated with E. coli, Salmonella, or Listeria and incubated for 48 hours at 35 0 C. Each test was run in triplicate. The results in terms of CFU and log 10 CFU are shown in Tables 8-10.
