PHILADELPHIA (CBS) – The Procter & Gamble Company has retrieved a single production lot of their Iams ProActive Health Smart Puppy dry dog food due to aflatoxin levels that were detected above the acceptable limit. This product has already been retrieved from store shelves. But if you have purchased it prior to last week, Iams urges consumers to check the code numbers and discontinue use immediately and discard it.

This particular puppy food may contain excess amounts of aflatoxin, which is a naturally occurring by-product from the growth of Aspergillus flavus. It can be harmful to pets if consumed in significant quantities. If ingested, your pet may exhibit symptoms of illness including sluggishness or lethargy combined with a reluctance to eat, vomiting, diarrhea, and a yellowish tint to the eyes or gums. If this occurs, your puppy should be seen by your veterinarian.

The affected puppy foods have the expiration dates of February 5 or February 6, 2013. The version, code dates, and UPC Codes are as follows:
