With the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) declaration of Escherichia coli O157:H7 and Shiga toxin-producing E. coli (STEC) as adulterants in non-intact raw beef products and intact raw beef products intended for non-intact use (FSIS, 2012), adding antimicrobial interventions has become standard procedure during beef harvest and further processing.
After a series of salmonellosis outbreaks linked to ground beef that occurred annually from 2011 to 2013, FSIS released a two-year Salmonella action plan that contained 10 objectives or activities, including: "Explore the contribution of lymph nodes to Salmonella contamination" and "Pre-harvest related activities."
The presence of Salmonella in beef products and development of methods to prevent that presence have been focal points for all sectors of the beef industry in recent years.
