³Positives on this table are not equivalent to positives on the Summary Year-to-Date or Serogroups tables because one sample may be positive for more than one serogroup.

⁴Sample Sources may include these types of establishments and types of samples:

Federal
Import (For Import samples, the column "Where Collected" is defined as Country of Origin.)
Federal Follow-up to a Positive Raw Ground Beef (RGB) Sample - A Raw Ground Beef Component (RGBC) Sample
Federal Trim Verification (RGBC) Sample
Federal Follow-up to a Positive RGBC Sample - A RGBC Sample
Federal RGBC Other Than Trim Verification Sample

⁵Samples Analyzed the Year column refers to the total number of samples analyzed for the year at the time of the positive result. For the most current analyzed totals, see the Year-to-Date Summary tables.

⁶Totals: "Total Positives" and "Total Samples Analyzed" are the totals since FSIS began its testing program to detect E. coli O157:H7 in raw ground beef components in 2007 and non-O157 STECs in 2012. This is the number of samples through the sample analysis completion date.
