hepatitis AHealth officials have linked cases of hepatitis A around the country to a Madison County farm. Fourteen people who work on the farm or were guests there are suspected to have contracted the disease, the Madison County Health Department announced at a news conference today.

Officials would not identify the farm. Hepatitis A has been confirmed in four Madison County residents, while 10 more cases are under investigation in North Carolina, South Carolina, Florida, New Jersey, Washington and Oregon.

The farm hasn’t sold any produce during the past two weeks.

Officials are also investigating the possibility that last month’s case at Trevi Restaurant & Gourmet Market in Asheville is connected to the farm.
