In 2011, after FSIS published its determination that six Shiga toxin-producing Escherichia coli:O26, O45, O103, O111, O121, and O145 (non-O157 STEC) were adulterants, the agency began testing beef manufacturing trimmings. FSIS also announced that when it completed a cost-benefit analysis, FSIS would consider expand its testing to include other raw ground beef components and ground product.
Although FSIS will accept comments on the cost-benefit analysis until Jan. 20, 2015, it appears FSIS ultimately will expand the non-O157 testing to the other raw products.
