A voluntary recall was issued for hundreds of thousands of cases of bags of shredded cheese sold at major retailers in October, according to the Food and Drug Administration.

More than 250,000 cases of cheese were recalled by the Great Lakes Cheese Co. in a voluntary recall to retailers on Oct. 3, an FDA report said. The report's classification date is marked Dec. 1 and described the recall as "ongoing."

A list of of brands named in the report include popular store-owned brands from Target, Aldi, Walmart, and H-E-B grocery stores such as Good & Gather, Happy Farms, Hill Country and Great Value.

It said that the cause for the recall was "potential metal fragments from supplier raw material."

This was labeled a Class II recall, which the FDA defines as having the potential to "cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote."

More than 30 states are affected by the recall including Alabama, California, Florida, Kansas, Minnesota, New York, New Mexico, and Wisconsin. Puerto Rico was also listed among places where the cheese may have been distributed.

The FDA report states that Great Lakes Cheese Co. did not issue a press release about the recall. Great Lakes Cheese Co. did not immediately respond to a request for comment from NBC News on Wednesday.
