Broccoli florets Walmart stores in 20 states have been under a recall since late last year. The FDA now has updated its recall notice for Marketside Broccoli Florets to Class I, meaning the product could be potentially deadly.

More than 5,900 bags of this Marketside Broccoli were sold. The states that are currently impacted by this recall are the following: Alaska, Arkansas, Arizona, California, Colorado, Idaho, Illinois, Indiana, Kentucky, Louisiana, Michigan, Montana, Nevada, Ohio, Oregon, Texas, Utah, Washington and Wyoming.

Last year, California-based grocery producer Braga Fresh voluntarily issued a precautionary recall of 12-ounce washed and ready-to-eat Marketside Broccoli Florets sold at more than 1,000 Walmart stores due to the possibility of Listeria monocytogenes contamination.
