We now know what killed 200 steers in Portage County earlier this month.
According to the Wisconsin Veterinary Diagnostic Laboratory, the animals were poisoned by a toxin found in moldy sweet potatoes.
The potatoes were then mixed with feed and fed to the steers.
During an interview with the University of Wisconsin in Madison, Peter Vanderloo, associate director from lab said the potatoes were never in the human food supply chain and there is no risk to human heath.
