McCain Foods has recalled onion rings because of concerns they may contain glass.

The onion rings were sold in 397 g bags with a lot code beginning with V40728 and a best before date of Oct. 28, 2015.

The onion rings were sold nationwide.

No one has reported becoming sick or injured from eating the onion rings, but the company says anyone who has the product should throw it out or return it to the store where it was purchased.

The company initiated the recall Friday after learning of a potential problem.
