TRI-CITIES, Tenn. (WJHL) — Some elementary school students in Sullivan and Washington counties are experiencing illness from an E. Coli infection after taking a field trip to see animals at the Appalachian Fairgrounds last week, the Northeast Regional Health Office reports.

According to a statement from the office’s Regional Medical Officer, Dr. David Kirschke, MD, elementary children in both Washington and Sullivan counties took a field trip on Sept. 26 and 27 to an animal exhibit at the fairgrounds in Gray. The illnesses reportedly occurred following this trip.

Dr. Kirschke said the health departments are working to identify the source of these infections, which includes performing environmental testing at the fairgrounds. He said advice for staying healthy while visiting with animals, especially non-domesticated, can be found on the CDC’s website.
