Bison E. coli Lawsuit Filed Against Rocky Mountain Natural Meats

GOLDEN, Colo. - A woman from Lakewood, Colo., who was hospitalized for an infection of E. coli O157:H7 after eating bison meat has filed a lawsuit against Rocky Mountain Natural Meats Inc. of Henderson, Colo., the processor of the meat.

The woman is represented by Pritzker Olsen law firm in the lawsuit filed by local counsel on July 8, 2010, in Jefferson County District Court. According to the complaint, the woman purchased the bison product at a King Soopers grocery store in Lakewood.

Health officials used pulsed-field gel electrophoresis (PFGE) to confirm that the strain of E. coli that infected the woman was genetically indistinguishable from a strain isolated from other people in Colorado. According to the complaint, health officials then concluded that the woman was part of an E. coli O157:H7 outbreak linked to Rocky Mountain Natural Meats bison meat that now has six confirmed cases, five in Colorado and one in New York.

In response to the outbreak investigation, Rocky Mountain Meats recalled 66,000 pounds of ground buffalo and bison steaks on July 2 that it said may be contaminated with E. coli O157:H7, a potentially deadly bacterium that is banned in ground beef. The recalled meat was sold under the following brands: Great Range, Nature's Rancher, The Buffalo Guys and Rocky Mountain Natural Meats.
