The tomatoes, recalled for potential salmonella contamination, were shipped to Georgia, North Carolina and South Carolina.

A tomato recall due to risk of salmonella contamination has been elevated by the U.S. Food and Drug Administration to its highest warning level. 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 Food and Drug Administration recalled deadly tomatoes in three Southern states early last month. However, the agency has now classified the alert as Class I, the highest level of contamination. The FDA announced the first of two tomato recalls on May 2 for potential salmonella contamination.
