(CBS) Tyson Foods Inc. is recalling about 33,840 pounds of mechanically separated chicken products due to fears it may be contaminated with Salmonella bacteria.

The U.S. Department of Agriculture s Food Safety and Inspection Service (FSIS) and Tyson Foods said that they were voluntarily recalling some 40-pound cases, which contained four 10-pound chubs of Tyson Mechanically Separated Chicken. The products were produced on Oct. 11, 2013.

The chicken was intended for institutional use only across the country, and would not have made its way for consumer purchase in retail stores. This particular product was shipped to centers in California, Florida, Indiana, Kansas, Nevada, New Jersey, Ohio, and Wisconsin.

The products can be identified by the P-13556 establishment number, which is located inside the USDA mark of inspection. The case code is 2843SDL1412 -- 18.

The recall was issued after FSIS became aware of people at a Tennessee correctional facility being infected with a particular strain of the bacteria, Salmonella Heidelberg, on Dec. 12, 2013. Seven people had been sickened by the bacteria between Nov. 29, 2013 to Dec. 5, 2013. Two of them required hospitalization.

After working with the Tennessee Department of Health, it was determined that the patients had consumed the chicken in question. The investigation remains ongoing.

The public can contact Tyson Consumer Relations department at 866-886-8456 with any concerns.
