The State Health Department is trying to head off a Salmonella outbreak after dozens of people in southern Marion and northern Johnson counties have reported cases in recent days.

The State Health Department says it normally sees a few cases a year. “But we are seeing quite a dramatic increase,” Lynae Granzow with the department told WISH-TV.

Granzow is leading a formal investigation, “We are looking at many different sources in the Greenwood area.” Granzow won’t speculate on a specific source but says there are many possibilities. In the past, everything from ice cream to iguanas have been blamed for outbreaks.
