All these products have a “USE BY/SELL BY DATE” of June 14, 2013. The products were produced on May 25, 2013, and shipped to various institutions and retail establishments. FSIS and the establishment are concerned that some product may be frozen and in shoppers’ freezers.

The problem was discovered through routine FSIS monitoring which confirmed a positive result for E.coli O157:H7. An investigation determined the firm was the sole supplier of the source materials used to produce the positive product. FSIS and the company have received no reports of illnesses associated with consumption of these products.
