BJ’s Wholesale Club, Inc. is recalling its 25-count packages of "Berkley & Jensen" Full-Cut Pig Ears dog treats with no lot number and only the expiration advisory "BEST IF USED BY 2009" (without referencing a specific month) because they have the potential to be contaminated with Salmonella, an organism which can cause serious infections in dogs, and, if there is cross contamination, young children, frail or elderly people, and others with weakened immune systems.
