The Centers for Disease Control and Prevention is investigating a salmonella outbreak that has touched 19 states so far, including Georgia, Channel 2 Action News reported.

More than 90 people, including four in Georgia, have gotten sick, and 10 people have been hospitalized. Of the four local cases, three are in Fulton County and one in Cobb, Channel 2 said.

The Food and Drug Administration is working with the CDC to find the source of the problem.

According to an FDA memo distributed Tuesday, the salmonella may be linked to sushi, specifically "highly suspect" spicy tuna rolls, the Associated Press reported.

"It is too early to speculate on the cause of the outbreak," FDA spokesman Curtis Allen told the AP.

Symptoms of salmonella illness include vomiting, diarrhea, abdominal pain and fever.
