BAKERSFIELD, Calif. -- Public Health Services announced today that Huntington Meat Packing delivered meat potentially contaminated with E. coli 0157:H7 to Kern County. The investigation is still ongoing to determine which schools, restaurants and food establishments may have received the product. The Kern County Superintendent of Schools and all school districts have been notified and are taking appropriate action.

Huntington Meat Packing, a Southern California meat packing firm, has expanded its recall of ground beef and veal potentially contaminated with E. coli 0157:H7, which includes approximately 4.9 million pounds of products by Huntington Meat Packing under the Huntington, Imperial Meat and El Rancho brands. The original recall, announced Jan. 18, was for 864,000 pounds of meat.

E. coli is a potentially deadly germ that can cause bloody diarrhea, dehydration and, in severe cases, kidney failure. The germ can be killed by cooking fresh and frozen meat products to an internal temperature of 160 degrees.

There have been no reports of illnesses associated with consumption of the products, the food safety agency said.

The original recall was expanded based on evidence collected in an ongoing criminal investigation. Inspectors found the products were prepared in a manner that did not follow rules to prevent food safety hazards, officials said.

The products subject to recall include:

The community is reminded to cook all ground beef and hamburger thoroughly. Because ground beef can turn brown before disease-causing bacteria are killed, use a digital instant-read meat thermometer to ensure thorough cooking. Ground beef should be cooked until a thermometer inserted into several parts of the patty, including the thickest part, reads at least 160 degrees F. Persons who cook ground beef without using a thermometer can decrease their risk of illness by not eating ground beef patties that are still pink in the middle.
