EMPORIA, Kan. (AP) -- Federal agriculture officials say Tyson Fresh Meats Inc. is recalling about 131,300 pounds of ground beef that might be contaminated with E. coli.

The U.S. Department of Agriculture announced Wednesday that the department became aware of the problem when health officials notified the agency Monday about E. coli illnesses in Butler County, Ohio. Ground beef collected from the patients' homes tested positive for the bacteria.

The products being recalled include Kroger-brand ground beef; Butcher's Brand beef and generic label beef. All the beef was produced Aug. 23. The Kroger beef has a product code of D-0211 QW; the Butcher's Brand code is D-0211 LWIF and generic label's product code is D-0211 LWI.

A request for comment from a Tyson Foods spokesman was not immediately answered.
