The Monroe County Fair shut down its swine barn Tuesday after concerns about a potential flu outbreak among the animals and some people, reports IndianaPublicMedia.

State Board of Animal Health spokesperson Denise Derrer says it is not just Monroe County that has prompted action at the State Fair.

“We’ve actually been hearing that there are more pigs coming down with illness following fairs and then they get home, they’re coming home sick,“ he says.

State Veterinarian Bret Marsh says all pigs coming onto the state Fairgrounds this year will have their temperature taken to establish a baseline. Any swine with temperatures over 105 degrees will be turned away. And while some people around the state have also shown symptoms of illness, Mr Marsh says it does not appear to be affecting visitors to any fairs.

“Human cases with this particular virus have been in people that have had direct contact with pigs,“ he says. “So it’s exhibitors or families that are exhibiting pigs at the fairs.“

Mr Marsh says pigs will be regularly monitored throughout the State Fair to ensure the health and safety of the animals and their handlers.
