The U.S. Food and Drug Administration says more than 3,500 bags of dog treats have been recalled over metal contamination concerns.

Richmond, Virginia-based TDBBS is recalling 3,551 bags of its Green Tripe dog treats distributed to stores nationwide and sold online in February and May, the FDA announced Friday.

The recall affects two brands sold by the company, Barkworthies and Best Bully.

No injuries or illnesses have been reported, according to the FDA.

USA TODAY reached out to TDBBS and did not receive an immediate response Monday.

What to do if you have the recalled treats

Pet owners who have bought the treats are advised to immediately throw them away. Consumers interested in a return can contact the company directly.

Those who may have already fed the contaminated treats to their pets are advised to look for signs of illness or unusual behavior. If a pet shows these signs, contact a veterinarian immediately.

The recall announcement said that the company is working with distributors and retailers to ensure that the treats are taken off of store shelves.
