On May 7, 2012, the Food Safety and Inspection Service (FSIS) posted a Federal Register Notice titled: “Traceback, Recall Procedures for Escherichia coli O157:H7 Positive Raw Beef Product, and Availability of Compliance Guidelines.”
On May 7, 2012, FSIS announced that its traceback policy was about to change. Previously, in the event of a positive E. coli O157:H7 regulatory finding in finished ground beef, or in the event of a foodborne illness outbreak linked to ground beef, FSIS rarely would attempt to demine the original source of the contamination.
