A concentrated quaternary ammonium compound (QAC) solution comprising a QAC with a concentration greater than about 10% by weight and at least one solubility enhancing agent, such as an alcohol, is disclosed. A diluted QAC solution is useful on food products to prevent microbial growth on the food from a broad spectrum of foodborne microbial contamination. Also disclosed is a method of contacting food products with the dilute QAC for an application time of at least 0.1 second. 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 10 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.

Concentrated, non-foaming solution of quarternary ammonium compounds and methods of use

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. New formulations of quaternary ammonium compounds combined with glycerin and/or ethyl alcohol provides a concentrated formulation for industrial use and a diluted formulation for use in spraying methods.

Method for the broad spectrum prevention and removal of microbial

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 exposed to excitation light of a selected bandwidth(s) and certain bandwidth(s) is(are) measured and compared to a threshold, above which indicates contaminants. Suitable excitation bandwidth and measuring bandwidth are selected such that the ratio of or difference between the resulting sample fluoresence and contamination fluoresence are greater then a certain ratio or difference. If contaminants are present, a controller can generate a signal and/or send the contaminated items to a wash station.

Method and system for fecal detection

A composition and method for removing and preventing Salmonella contamination of meat products, in particular poultry. The composition comprises an effective amount of a quaternary ammonium compound in an aqueous solution. The quaternary ammonium compound are selected from the group consisting of alkylpyridinium, tetra-alkylammonium, and alkylalicyclic ammonium salts. Preferably, the quaternary ammonium compounds are cetylpyridinium chloride (CPC) and cetylpyridinium bromide (CPB). The method comprises treating meat and poultry products with an effective amount of the quaternary ammonium compound in an aqueous solution. Mutagenicity studies are also disclosed.

Use of quaternary ammonium compounds to remove salmonella contamination

A method for the reduction or elimination of microbes in liquid or food products whereby the passage of a waveform, such as a DC square-wave, of a specific amplitude, duty cycle and current through the liquid or food product for a specific time period, allows for the elimination of microbes such as Salmonella Typhimurium from a variety of substances, including water, milk and solid food products.
