OCALA, Fla. — A bus carrying farmworkers in central Florida overturned on Tuesday, killing eight people and injuring about 40 other passengers, authorities said.

The bus was transporting 53 farmworkers when it collided with a truck in Marion County, north of Orlando, the Florida Highway Patrol said.

Authorities say the bus swerved off a road. It crashed through a fence and ended up on its side in a field. The workers were being transported to Cannon Farms in Dunellon, which has been harvesting watermelons.

“We will be closed today out of respect to the losses and injuries endured early this morning in the accident that took place to the Olvera Trucking Harvesting Corp.,” Cannon Farms announced on its Facebook page. “Please pray with us for the families and the loved ones involved in this tragic accident. We appreciate your understanding at this difficult time.”

Cannon Farms describes itself as a family owned commercial farming operation that has farmed its land for more than 100 years, focusing now on peanuts and watermelons, which it sends to grocery stores across the U.S. and Canada.
