About the Testing Program

2012, Testing for non-O157 Shiga toxin-producing E. coli 

FSIS considers raw, non-intact beef products or the components of these products found to have six Shiga toxin-producing Escherichia coli (STEC) to be adulterated, in addition to E. coli O157:H7. (Refer to the Federal Register notice Shiga Toxin-Producing Escherichia coli in Certain Raw Beef Products | PDF). These six non-O157 STECs are O26, O45, O103, O111, O121, and O145.

On June 4, 2012, FSIS began verification testing for these non-O157 STEC in domestic and imported beef manufacturing trimmings from cattle slaughtered on or after June 4, 2012. Beef manufacturing trimmings collected from cattle slaughtered before June 4, 2012, or that contain other components such as cheek meat are analyzed for E. coli O157:H7 only.
