  • Publication number: 20050239850
    Abstract: A method of using quaternary ammonium compounds for inhibiting attachment of and removing a broad spectrum of foodborne microbial contamination from food products. The method uses quaternary ammonium compounds for inhibiting attachment of and removing microorganisms such as, Staphylococcus, Campylobacter, Arcobacter, Listeria, Aeromonas, Bacillus, Salmonella, non-toxin-producing Escherichia, and pathogenic toxin-producing Escherichia, such as 0157:H7; fungi, such as Aspergillus flavus and Penicillium chrysogenum; and parasites, such as Entameba histolytica from a broad range of food. The foods that can be treated by this method are meat, seafood, vegetables, and fruit. One of the treatment methods is spraying quaternary ammonium compounds on the food products to prevent broad spectrum foodborne microbial contamination.

  • Publication number: 20050113012
    Abstract: A concentrated quaternary ammonium compound (QAC) solution comprising a QAC with a concentration from greater than about 10% by weight and at least one solubility enhancing agent, such as an alcohol, is disclosed. A diluted QAC solution is used to contact food products to prevent microbial growth on the food products from a broad spectrum of foodborne microbial contamination. A method of contacting the food products with the dilute QAC for an application time of at least 0.1 second is disclosed. The foods that can be treated by this method are meat and meat products, seafood, vegetables, fruit, dairy products, pet foods and snacks, and any other food that can be treated and still retain its appearance and texture. One of the treatment methods is spraying and misting the QAC solutions on the food products for an application time of at least 0.1 second to prevent broad spectrum foodborne microbial contamination.

  • Patent number: 6083463
    Abstract: A water system for supplying chilled water to a food production line. The chilled water is held in a holding tank which is sampled by a pump which delivers water to an analyzer. The water is first filtered to remove debris that would hamper the analysis. The analyzer determines the disinfectant level in the water, and generates a signal indicative of that level. When the disinfectant level falls below a predetermined level, a disinfection pump is activated to deliver additional disinfectant to the tank. The preferred disinfectant is Liquid Chlorine(sodium hypochlorite). The analyzer can measure the free available chlorine level, pH or oxidation-reduction potential of the water.

  • Patent number: 5895921
    Abstract: A method of and apparatus for detecting the presence of fecal or ingesta matter contaminants on a poultry or meat item. The poultry or meat is conveyed in front of a UV light transmitter/receiver where UV light is directed onto the poultry or meat item and subsequently light is gathered from the poultry or meat. The gathered light is then compared to a threshold, above which indicates contaminants. If contaminants are present, the controller can generate a signal and/or send the contaminated items to a wash station.
