FSIS Directive 10,010.1 states in part:

Products Not Subject To FSIS Sampling

Ground buffalo or bison is also not a raw ground beef product subject to this FSIS verification sampling.

Not testing Buffalo or Bison seems a bit curious given that we have now had at least two recalls in the past three years, and given that Buffalo and Bison are known carriers of E. coli O157:H7.

In July 2007, Custom Pack, Inc., recalled approximately 5,920 pounds of ground beef and buffalo products because they may be contaminated with E. coli O157:H7. Each package bore the establishment number “Est. 5650” inside the USDA mark of inspection. The ground beef products were produced between June 1 and June 13, 2007, and were distributed to restaurants and institutions in Nebraska. The ground buffalo patties were produced on June 7, 2007, and distributed to restaurants and institutions in Colorado.

Now in July 2010, Rocky Mountain Natural Meats is recalling approximately 66,760 pounds of ground and tenderized steak bison products after FSIS became aware of the problem during the course of an on-going investigation into a cluster of E. coli O157:H7 illnesses in Colorado with illness onset dates between June 4, 2010 and June 9, 2010. Working in conjunction with the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration, the Colorado Department of Public Health and Environment and the New York Department of Health, 5 case-patients have been identified in Colorado as well as 1 case-patient in New York with an indistinguishable PFGE pattern. FSIS determined that there is an association between the ground bison products and the cluster of illnesses in the state of Colorado. These products were distributed to retail establishments nationwide and food service distributors in Utah, Arizona, and Nevada and of course Colorado and New York.

The products subject to recall bear the establishment number “EST. 20247” inside the USDA mark of inspection. These products were produced between the dates of May 21, 2010 through May 27, 2010.
