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.

The recalled tomatoes, packaged in trays and boxes, were shipped to Georgia, North Carolina, and South Carolina.

A batch of South Carolina-grown tomatoes from William Farms Repack LLC sold in the state was recalled by the FDA for potential salmonella contamination.
