Two hogs at the Franklin County Fair tested positive for swine influenza July 19, said David Fleshman, president of the Franklin County Agricultural Society, which organizes the fair.

A 4-H exhibitor noticed a pig "acting differently" and reported the behavior to an on-staff veterinarian, Fleshman said, and it was determined the animal had influenza.

In turn, fair officials called the Ohio Department of Agriculture, and all 50 hogs on exhibit at the fairgrounds were tested, Fleshman said.

Two tested positive, he said.

“Protocol was followed,” he said, and by 10 p.m. July 19 all 50 hogs had been removed and the area quarantined.

The Ohio Department of Agriculture took custody of the two pigs that tested positive but the other 48 proceeded to market in the same manner they normally would have, Fleshman said.

However, the 4-H exhibitors that would have shown hogs during the 4-H Junior Fair livestock auction on July 22, the final day of the fair, will not have animals to exhibit.

Fleshman said buyers still could bid on the pigs, but they won't be on display in the pen.

No other livestock were affected, Fleshman said.
