Hundreds of piglets ran free on an Ohio highway on Monday, June 8, after a semi truck accident let the animals escape.

The truck, which contained 2,200 piglets, was en route from South Carolina to Indiana, where the pigs were headed to a feeder farm to be raised and eventually slaughtered. But the truck overturned on U.S. Route 35 near Xenia Township, OH, spilling over and causing hundreds of pigs to run into the nearby woods.

Volunteers and emergency personnel worked to wrangle the pigs in the aftermath of the accident, which occurred around 7:30 p.m. that night.

Xenia Township Fire Chief Dean Fox explained that so many of the pigs had run into the woods that it would be difficult for workers to catch them all. “We’ll try as hard as we can to retrieve all of them, but we probably won’t retrieve them all,” he told local reporters.

Unfortunately, not all of the pigs were so lucky as those who got to roam free for a little bit.

Around 300 to 400 of the piglets were thought to have died in the accident; many were so badly injured that they would have to be euthanized, according to rescue workers. In the U.S. alone, trucking accidents take around 4,000 human lives each year.

The highway remained closed into the evening as workers cleaned up the accident. The driver of the truck, who was from South Carolina, had gone too fast around a curve and hit a guardrail, which caused the semi truck to roll over.

The driver was unharmed, but a passenger with him was taken to a local hospital to have injuries treated. The driver was also cited for failure to control a motor vehicle.

As for the pigs that made it out alive, those that were caught were taken to the Greene County Fairgrounds, where they were given water and a space to calm down. Officials wanted to collect as many of them as possible, so they wouldn’t become prey for coyotes in the area.
