Mars Petcare US is voluntarily recalling a limited range of three varieties of Pedigree weight management canned dog food products due to a potential choking risk.

The affected product may contain small pieces of blue plastic, which entered the food during the production process. The company says that the source of the plastic has been identified and the issue resolved.

Mars is encouraging consumers who purchased the affected product to discard the food or return it to the retailer for a full refund or exchange. While a small number of consumers have reported finding the plastic pieces, Mars says it has not received any reports of injury or illness associated with the affected product.

Affected product was distributed to retail customers throughout the United States. Mars Petcare US is working with all of our distributors and retail customers to ensure that the recalled products are no longer sold and are removed from inventory.

Each recalled product will have a lot code printed on the end of the can that begins with 209, 210, 211 or 212 and a "best before" date that falls between 2/24/2014 and 3/23/2014.
