The Food and Drug Administration has upgraded its classification of a broccoli recall initially reported in late December, labeling it as “Class I” — the agency’s most serious recall

The FDA made the recall due to a possible bacteria contamination which can cause "serious and sometimes fatal infections."

The FDA has upgraded a recall issued on 12-ounce Marketside Broccoli Florets that were initially sold at select Walmart stores across the United States.

Nine states have been identified as being affected by the chocolate recall, but the products were available online so others could have the products as well. Consumers affected bought products from the retail store located at 5158 Clayton Road, Suisun Valley, CA 94534, and online through calyeefarm.com.

The FDA has updated the December recall of some of Cal Yee Farms' products to the highest risk level classification for three of its chocolate products, warning that exposure or consumption could cause death.

Multiple chocolate-covered products recalled in December due to mislabeled packaging and undeclared substances have been hit with FDA's Class 1 classification.

Cal Yee Farm, a California-based company, announced a recall on a variety of products, including dark chocolate walnuts, apricots and yogurt-coated almonds, after the FDA discovered that they weren’t labeled properly.

The FDA defines a Class 1 recall as “a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death." The affected products that fall into this new classification include Cal Yee Farms dark chocolate almonds,

Echoing a move it made regarding potato chips, the Food and Drug Administration recently raised the alert level for a chocolate recall to the highest risk level due to the possibility of undeclared allergens.
