Dog food manufacturer Bil-Jac Foods is recalling one batch, 256 cases, of 6-pound Adult Select Formula Dog Food from retailers’ stores and warehouses due to a few reports of mold in bags from the batch.

The recall includes a total of 1,024 bags of dry dog food marked with batch number 1792-02 and an expiration date of December 27, 2013. The yet-to-be-determined mold in some of the bags was caused by higher moisture content in the food, according to a statement on the company’s website.

“We’ve only found mold in a few bags; most of the batch was fine,” said Dr. Allen Bingham, a staff veterinarian for Bil-Jac Foods. “An outside laboratory is currently testing the food in the affected bags, and we are trying to make sure we know what’s going on; we’re being overly cautious.”

Consumers with questions about refunds or returns may call +1.800.321.1002 x239, and ask for Shannon, during business hours, Monday to Friday, EDT.
