More than one million bags of cheese sold at popular stores like Walmart, Target and Aldi have been recalled for possibly containing metal pieces, according to a recently updated Food and Drug Administration (FDA) report.

Ohio-based Great Lakes Cheese Co. initiated the ongoing recall on Oct. 3, stating the affected cheese may be contaminated with metal fragments, which could cause injury if consumed.

The FDA reclassified the recall to a "Class 1" on Dec. 1, according to an enforcement report, meaning the food "may cause temporary or medically reversible adverse health consequences.”

The recalled cheese products were different mixes sold in 31 states under an array of brand names, including store brands such as Good & Gather, Great Value, Publix, Sprouts and Happy Farms.

It is unclear whether any injuries have occurred in relation to the ongoing recall. USA TODAY contacted Great Lakes Cheese Co. on Wednesday, Dec. 3, but has not received a response.

Here's what to know about the recall.
