Tyson Foods is recalling 34,000 pounds of chicken products over fears of salmonella contamination.

The U.S. Department of Agriculture says chicken from Tyson was linked to an outbreak of illness at a Tennessee prison. Seven inmates got sick, two of them were hospitalized.

Tyson says the mechanically separated chicken at the center of the recall was produced on October 11, and sold in 40-pound cases containing four 10-pound chubs. The products were not available for retail sale to restaurants or consumers, and were shipped for institutional use only, nationwide.

Consumers with questions about the recall should contact Tyson Foods' consumer relations department at 866-886-8456. More information is available on Tyson's website.

About 48 million people contract some form of food poisoning each year, according to the CDC, and salmonella is the leading cause of foodborne illness. Salmonella causes an estimated 1.3 million illnesses each year in the United States. In December, the FSIS announced that it hopes to tackle that toll with the help of a new "Salmonella Action Plan."
