Title: Preharvest Bacterial Treatments that Control Foodborne Pathogens

Patent Number: 6475527
Docket Number: 12799
Serial Number: 9354446
Date Patented: 11/05/2002

Technology Description:

ARS scientists have discovered that feeding chlorate to livestock animals prior to shipment to slaughter inhibits growth of pathogens such as Salmonella, Escherichia coli, and Campylobacter in pigs and cows. Because the gut and lymph tissue of meat animals and chickens are major reservoirs for Salmonella and E. coli O157:H7, this invention is a way to reduce on-farm concentrations of these harmful pathogens. Fewer bacterial pathogens in the gut can significantly reduce the chance of carcass contamination during food processing. These bacterial pathogens are associated with many cases of human foodborne illnesses. Currently, no strategies exist for preharvest animal treatments in the beef and pork industries for controlling these pathogens.

Biotechnology companies involved in developing vaccines and treatments for preventing or treating bacterial pathogens in animals could use this invention.
