A tomato recall due to risk of salmonella contamination has been designated as Class I, the U.S. Food and Drug Administration's highest warning level, the agency said. The FDA marked the tomato recall affecting three states as Class I, meaning there is a risk of "serious adverse health consequences or death," on May 28.

Williams Farms Repack issued a recall for the tomatoes, the FDA announced last month. It's now labeled deadly.

What was once a cautioned recall due to the possible presence of Salmonella in tomatoes sold in three states is now labeled as "deadly."
