Two lots of Pedigree-branded dog food were recalled over the potential presence of metal and plastic.

Mars Petcare US issued the voluntary recall on July 2 for 13.2 oz cans of High Protein Chopped Chicken & Duck Flavor for dogs, according to a company announcement.

The affected products include lot codes 613C3KKCFC and 613C1KKCFC.

The recalled items did not meet Mars and Pedigree safety and quality standards, the company said. As part of the quality control process all Pedigree products go through, these two lots were sent to a third-party vendor for destruction.

But Mars later discovered that the product had been fraudulently diverted and sold into the U.S. marketplace.

“The potential presence of sharp metal and plastic foreign material in the cans could pose a hazard to your dog,” the company announcement reads.

The company warned that health risks to dogs ingesting sharp foreign objects can include choking and lacerations or blockages in the gastrointestinal tract.

Anyone who purchased the affected dog food is instructed not to feed it to their pet and to contact Pedigree for a replacement.

Consumers who are concerned after feeding the recalled product to their dog are urged to contact their veterinarian.

The company said no illnesses or injuries have been reported.

“Mars is working with authorities to determine how these products entered the marketplace. We are committed to protecting pets and helping consumers identify and remove the affected products from use,” the company said.
