California chicken producer Foster Farms is recalling an unspecified amount of its chicken products because the products may be contaminated with a strain of salmonella Heidelberg, according to a Department of Defense All Food and Drug Activity message sent July 9.

The U.S. Department of Food and Agriculture said Thursday it has found evidence directly linking Foster Farms boneless-skinless chicken breast to a case of Salmonella Heidelberg, an antibiotic-resistant strain of the disease that has sickened more than 500 people in the past 16 months and led to pressure from food safety advocates for federal action against the company.

As a result, Foster Farms issued a recall for 170 different chicken products that came from its Fresno facilities in March.

The Defense Commissary Agency has publicized this recall to all its stores. Whenever a commissary has a recalled or withdrawn product in its inventory, the product is immediately removed from store shelves.

"These products were produced in March," said Richard Stith, lead consumer safety officer for DeCA headquarters at Fort Lee, Va, in a news release. "Our patrons could have this product frozen in their homes. This product should not be consumed."

The Foster Farms recall affects specific chicken products sent to the following commissaries:

Alaska - Eielson Air Force Base

Arizona - Davis-Monthan Air Force Base, Fort Huachuca and Luke Air Force Base
