It has been over a year since the Food Safety and Inspection Service (FSIS) declared six non-O157 STECs as adulterants on raw non-intact beef, and almost five months since the agency started testing beef trimmings for these pathogens.
On June 4, six non-O157 STECs (O26, O45, O103, O111, O121, O145) officially became per se adulterants in various raw beef products. On that date, FSIS began analyzing raw beef manufacturing trimmings for these six.
