ARS researchers led by microbiologist Robin Anderson at the
Food and Feed Safety Research Unit (FFSRU) in Texas mixed a chlorate-based compound into livestock feed or water two days before slaughter. When fed at roughly 0.5 to 5 percent of an animal’s diet, this powder-like additive was very effective in reducing Salmonella and
E. coli O157:H7 in the animal’s gastrointestinal tract.
To test the chlorate compound in poultry, FFSRU microbiologist Allen Byrd gave it to more than 200 market-age turkeys and 2,000 broiler chickens 48 hours before they went to processing. The incidence of Salmonella dropped from 35 percent to zero in turkeys, and from 37 percent to 2 percent in broilers.
ARS has patented the technology, and FFSRU researchers are working to further develop it to make it ready for approval by regulatory agencies.
