"[The] driver failed to negotiate a curve on the roadway," said Sgt. Mark Ott from the Missouri State Highway Patrol. "He ran off the right side of the roadway and was unable to keep the truck upright. It overturned and went down the short embankment here."
Traffic was kept to one lane for several hours, while several agencies aided in the response.
The truck was carrying hogs, on its way to Triumph Foods in St. Joseph.
"From what I understand these are not Triumph's hogs," Sgt. Ott said. "They were on their way there but until they get there they're not actually theirs. Triumph does have a team here. Whenever there's a wreck here in our area or the Midland Empire they try to come out."
Troopers say crashes are common in this area, because of several S-curves between St. Joseph and Cameron, but not always with livestock involved. Many of the hogs were uninjured, but the response required a team effort. The first priority was making sure traffic could get through and containing the animals.
"Most livestock going to market - they don't like the pavement. Usually if they're in the grass you can corral them in the grass," Sgt Ott said. "These hogs are more than happy to stay in a little huddle. They're not trying to run off; they don't like to get on the pavement."
Some of the animals, injured in the crash, will have to be put down.
The driver of the truck declined medical attention.
The Highway Patrol is still investigating the cause of the crash.
