A Pennsylvania-based company has recalled more than 16,000 pounds of ground beef products shipped to Walmart locations nationwide due to concerns the meat may be contaminated with E.coli, the Department of Agriculture's Food Safety and Inspection Service has announced.

The agency said it is concerned that some of the recalled products may be in consumers' refrigerators or freezers.

"Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase," the agency said in its announcement.

The raw ground beef items were produced by Cargill Meat Solutions on April 26 and 27.

The products subject to recall all have the USDA mark of inspection on the front of the product label, and establishment number "EST. 86P" printed on the back of the product label.

These items were shipped to Walmart retail locations nationwide; officials did not specify which stores may have received the products. There have been no illnesses reported as of Thursday morning.

"Anyone concerned about an illness should contact a healthcare provider," the Department of Agriculture's Food Safety and Inspection Service said.

E.coli is a potentially deadly bacterium that can cause dehydration, bloody diarrhea and abdominal cramps two to eight days after exposure the organism. While most people recover within a week, some develop a type of kidney failure called hemolytic uremic syndrome. This condition can occur at any age but is most common in children under 5-years old and older adults.
