A lamb who won an award at a county fair in Ohio is under scrutiny after veterinarians discovered illicit drugs in its system, a report said.

The grand champion market lamb at a 4-H contest earlier this month in Logan County tested positive for diuretics before it was sent to slaughter, according to Ohio’s WCMH-TV.

“We don’t know how it got in there, and we may never know,” Dr. Tony Forshey, the state veterinarian at the Ohio Department of Agriculture, told the network.

“But it’s the exhibitor’s responsibility to present an animal to the fair for competition that’s free of all of those.”

The drug not only gives the animal an unfair advantage in competitions, but may contaminate its meat as well.

“You don’t want an animal with a ton of drugs in it because it might not be safe to eat and everything,” said one child who entered the competition.

The state requires every market grand champion be drug-tested before they’re sent to slaughter, the network said.

The Department of Agriculture is investigating and the lamb may have to forfeit its award pending the results.
