Broccoli florets sold in Walmart stores across 20 states that were recalled over bacterial contamination fears have been given the U.S. Food and Drug Administration (FDA)'s highest risk level. A single production lot of the washed and ready-to-eat Marketside Broccoli Florets by Braga Fresh were voluntarily recalled after random testing by Texas Health and Human Services in a store identified the presence of the bacteria Listeria monocytogenes.
