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.

The FDA announced the initial recall on Dec. 31, 2024, for Braga Fresh's washed and ready-to-eat 12-ounce bags of Marketside Broccoli Florets.

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.
