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 tomatoes were distributed in Georgia in April and are now a Class 1 recall, the FDA's most severe level that warns about possible deaths.
