Petfood manufacturer Procter & Gamble is voluntarily recalling select bags of Iams ProActive Health Smart Puppy dry dog food, due to aflatoxin levels detected higher than the accepted limit.

The recall is for 7-, 8-, and 17.5-pound bags of the Iams dog food, marked with expiration dates of February 5, 2013, and February 6, 2013. The affected bags were distributed in the following places in the US: Alabama, Connecticut, Delaware, Florida, Georgia, Louisiana, Maryland, Maine, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Pennsylvania, South Carolina and Virginia.

The company said no illnesses have been reported yet as a result of the contaminated petfood, but the recall is being issued as a precautionary measure. Pets that consume the product and show signs of sluggishness or lethargy, reluctance to eat, vomiting, yellowish tinted eyes or gums, or diarrhea should be taken to a veterinarian, the company says. Consumers who purchased the recalled food should stop using it immediately, throw it out and contact Iams for a replacement voucher.
