Mars Petcare has issued a voluntary recall for three varieties in its Pedigree brand weight management line of canned dog food due to a potential choking risk.

Cans of the recalled dog food may contain small pieces of blue plastic, which broke off a conveyor belt during the production process. The company says the issue has since been resolved at the manufacturing facility by replacing a conveyor belt with a redesigned tracking mechanism.

Products affected include Pedigree+ Healthy Weight premium ground entree in meaty juices, Pedigree Weight Management Beef & Liver dinner in meaty juices, and Pedigree Weight Management Chicken & Rice dinner in meaty juices. Each affected can has a lot code printed on the end that begins with 209, 210, 211 or 212, and a "Best Before" date between February 24, 2014, and March 23, 2014.

Affected products were distributed to retail customers throughout the United States. No other Pedigree products are affected, including any other variety of wet food, dry dog food, or dog treats. Consumers who purchased the product may contact the company at +1.877.720.3335.
