Oct. 27, 2014 -- More than 31,000 pounds of frozen chicken products have been recalled by a Pennsylvania company because of concerns about contamination with staph bacteria.

According to the U.S. Department of Agriculture (USDA), the contamination was discovered during a sampling program conducted by the Colorado Department of Agriculture. The company, Murry's Inc., is based in Lebanon, PA.

Staphylococcus aureus bacteria can cause food-borne illness and staph infections, the USDA said in a news release. Symptoms of food poisoning include nausea, vomiting, stomach cramps and diarrhea, and they usually develop within a few hours of when the contaminated food has been consumed.

The recalled products include Bell & Evans gluten-free chicken breast nuggets (12 ounces) and Bell & Evans gluten-free chicken breast (10.5 ounces), according to the USDA. All products have Aug. 9, 2015 expiration dates.

During a phone interview Sunday on "PBS NewsHour Weekend," Murry's Inc. Chief Executive Officer Ira Mendelson said no other company products were affected by the reported contamination.

"Even having knowledge of one box being contaminated, we felt a voluntary recall would be necessary," Mendelson said during the interview. No cases of food poisoning have been reported since the recall was issued on Saturday, according to Mendelson and the USDA.
