Macon County's Public Health Department is investigating 13 confirmed cases of salmonella. Diane Johner told the Decatur WAND that the health department is waiting for lab test results to help pinpoint the potential source.

Hand to mouth contact spreads salmonella bacteria, or through raw, unwashed food.

Washing your hands thoroughly can stop the bacteria's spread.

Symptoms include fever, diarrhea, nausea, and vomiting.
