Abstract

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.
