| Testing of Raw Ground Beef Component (RGBC) Samples for E. coli O157:H7
and non-O157 Shiga toxin-producing E. coli (STEC): Year-to-Date Totals |
|
 |
Table 1 presents the results from analysis of raw ground beef component samples for
non-O157 STECs. Results are from FSIS routine and follow-up sampling programs.
Table 2 presents the results from analysis of raw ground beef component samples for both E. coli O157:H7 and for the
non-O157 STECs by each non-O157 STEC serogroup. Information is based upon data in the FSIS electronic data
system as of April 21, 2013.

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. |

3 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.
