DAKOTA CITY, Neb. - Authorities are investigating the death of a Sioux City man fatally injured while working at the Tyson Foods plant in Dakota City.

Rodney R. Bridgett, 37, was injured about 11:45 a.m. Wednesday when a piece of equipment he was working on collapsed in the plant on Dakota Avenue, Dakota County Sheriff Chris Kleinberg said in a news release.

He said an ambulance crew took Bridgett to Mercy Medical Center - Sioux City, where he died shortly after 3 a.m. Thursday.

The incident appears to have been an accident, but Kleinberg said deputies will continue to investigate the matter until all medical reports have been completed.

Tyson spokesman Gary Mickelson said Thursday morning the meatpacking company's safety and operations management staff were investigating. They planned to notify officials from the Occupational Safety and Health Administration, he said in a statement.

The company's beef slaughter and processing plant was not in operation when Bridgett was injured, Mickelson said.

Tyson canceled Thursday morning's first-shift operations in the beef carcass production area of the plant as a result of the accident.
