Described is a method of sanitizing animal carcasses using aqueous streams having an antimicrobial composition added to the stream. Preferably, the antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C-Cperoxycarboxylic acid and a C-Cperoxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C-Cperoxycarboxylic acids and one or more C-Cperoxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

Treatment of animal carcasses

Described is a method of sanitizing animal carcasses using aqueous streams having an antimicrobial composition added to the stream. Preferably, the antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C&#x2013;Cperoxycarboxylic acid and a C&#x2013;Cperoxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C&#x2013;Cperoxycarboxylic acids and one or more C&#x2013;Cperoxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

The present invention is directed to cleaning compositions for metal surfaces, including both concentrates and ready-to-use solutions. These compositions include a source of calcium ion, a source of alkalinity, a chelating agent, and a surfactant. In some embodiments, a water-soluble or water-dispersible acid-substituted polymer is also included. Additionally, in some embodiments, specific surfactants or chelating agents are used to enhance the performance of the composition.

Alkaline metal cleaner comprising sulfonated-hydrophobically modified polyacrylate

Described is a method of sanitizing animal carcasses using aqueous streams having an antimicrobial composition added to the stream. Preferably, the antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C -C peroxycarboxylic acid and a C -C peroxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C -C peroxycarboxylic acids and one or more C -C peroxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

An antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C,-C,peroxycarboxylic acid and a C,-C,peroxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing meat product containing a mixture of one or more C,-C,peroxycarboxylic acids and one or more C,-C,peroxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

Antimicrobial composition for cleaning and sanitizing meat products
