TODAY’S PATENT – TREATMENT OF ANIMAL CARCASSES

The Treatment of animal carcasses was invented by Timothy A. Gutzmann, Brian J. Anderson, Pamela J. Reed, Bruce R. Cords, Lawrence A. Grab, and Edward H. Richardson and is been patented by USPTO on 26^th September 2017 bearing patent no. US9770040B2. This patent has been assigned to Ecolab USA Inc.

This method reduces surface microbial populations by at least one log10 in animal carcasses. This method involves cleaning and sanitizing the carcass and treating it with an antimicrobial composition containing at least 2 ppm peroxy carboxylic acids and carboxylic acids. Peroxyacetic and peroxy octanoic acids, lactic acid, hydrogen peroxide, and sequestering agents can be used to clean and sanitize animal carcasses.

A fourth method sprays an aqueous antimicrobial treatment composition on the carcass at 50 psi and 60°C. Spray, immerse, foam, thicken, gel, hoover, or light treat the composition. Pre-, concurrent-, or post-application thermal treatment is possible. An aqueous spray at 50 to 500 psi gauge is used to treat carcasses with the invention. The high-pressure spray and antimicrobial materials of the aqueous treatment eliminate microbial populations.

Bactericidal or bacteriostatic cell damage determines antimicrobial efficacy. Sanitizers and disinfectants reduce microbial populations by five-fold after 30 seconds. Reversible growth inhibitors or bacteriostatics are preservatives. The minimum acceptable microbial reduction for meat processing is one log10. Increased microbial reduction protects processed carcass meat.
