  Salmonella and E. coli O157:H7 are insidious problems for the beef industry. Asymptomatic fecal shedding of these pathogens contaminates the hide and carcass. Furthermore, Salmonella are unique in their ability to infiltrate lymph nodes leading to the post-harvest contamination of ground beef. These contaminations yield the two most important food safety hazards associated with the consumption of beef. Herein, we report the anti-Salmonella and anti-E. coli O157:H7 effects of a novel Saccharomyces cerevisiae fermentation prototype (PRT; NaturSafeTM) fed to feedlot cattle. Cattle fed PRT were compared to those fed a combination of monensin, tylosin, and a direct-fed microbial- a standard conventional practice in the U.S. beef industry. In this investigator-blinded study, 1,495 feedlot heifers (300-400 kg) were fed PRT (n=747 heifers) or the standard industry.. Read More»
