General Mills is voluntarily recalling Gold Medal flour, Wondra flour, and Signature Kitchens flour (sold in Safeway, Albertsons, Jewel, Shaws, Vons, United, Randalls, and Acme) due to possible E. coli O121 contamination.
Sate and federal authorities have been researching 38 occurences of illnesses across 20 states related to a specific type of E. coli (E. coli O121), between December 21, 2015 and May 3, 2016. While attempting to track the cause of the illness, CDC found that approximately half of the individuals reported making something homemade with flour at some point prior to becoming ill. Some reported using a General Mills brand of flour (source).
To date, there have been four confirmed cases in Michigan. Due to the long shelf life of flour, this outbreak could continue for an extended period of time. We urge you to take a look at the products in your cupboard and check UPCs and Better if Used By Dates. Information can be found here: General Mills Flour.
