¹ Results are posted according to the sample analysis completion date. 
² FSIS test results for the 6 target non-O157 STECs appear for only samples of beef manufacturing trimmings from cattle slaughtered on-site on or after June 4, 2012. At this time, only beef manufacturing trimmings and not components (such as bench trim, or other components of ground beef such as cheek meat and head meat) are eligible for testing for non-O157 STEC, as well as E. coli O157:H7. 
³ The Number Positive column on this table includes all samples that were positive for non-O157 STEC overall and does not reflect the total number of individual positive serogroups listed in the Non-O157 STEC (by serogroup) and E. coli O157:H7 table. This is due to the possibility that one sample may be positive for multiple serogroups.

⁴ Percent Positive 
⁵ (Number positive/number analyzed). Positives and Percent Positives on this table include all serogroups tested and do not reflect the total number of individual positive samples on the Individual Positives and the non-O157 STEC YTD tables. This is due to the possibility that one sample may be positive for multiple serogroups.
⁶ Mixed source is composed of both beef and veal products.
