Treatment of animal carcasses
First Claim
1. A method of treating an animal carcass to reduce a microbial population in resulting cut meat, the method comprising:
- diluting a concentrated antimicrobial composition, wherein the concentrated antimicrobial composition comprises;
(1) about 20% to about 50% acetic acid, and at least about 0.5% peracetic acid (PAA), or(2) at least about 0.5% acetic acid, and about 0.5% to about 20% peracetic acid (PAA); and
treating the carcass with the diluted antimicrobial composition for at least about 10 seconds, the diluted antimicrobial composition comprising;
(i) at least about 2 parts per million (ppm) of one or more mono- or di-peroxycarboxylic acids having up to 12 carbon atoms;
(ii) at least about 20 ppm of one or more carboxylic acids having up to 18 carbon atoms,thereby reducing the microbial population by at least one log10 reduction.

Abstract
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 C2-C4 peroxycarboxylic acid and a C8-C12 peroxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C2-C4 peroxycarboxylic acids and one or more C8-C12 peroxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.
