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.

Riverside has conducted an extensive investigation where the recalled products were manufactured, and has identified the source of the issue in the manufacturing process. The company has remediated the issue and tested the new processes to ensure that any future risk is fully mitigated.
