Many varieties of MadeGood bars are feared to pose a serious health risk, according to the FDA. Worse, some of the products are holiday themed. Few things satisfy a sweet-but-healthy snack craving like a granola bar.

Chicago-based Riverside Natural Foods is voluntarily recalling certain batches of MadeGood granola bars due to potential metal contamination, according to a Dec. 10 recall notice from the U.S. Food and Drug Administration.

A range of granola bars have been pulled from the shelves and shoppers are being warned not to eat them as small pieces of metal may have got into the mix. Brand Organic is recalling various MadeGood Granola Bars because they contain pieces of metal.
