Stevens Point–According to the Wisconsin Veterinary Diagnostic Laboratory in Madison, the death of approximately 200 steers in the town of Stockton was not a sign of the apocalypse, rather the result of moldy potatoes ingested by the herd.
A report written by Terry Devitt at the University of Wisconsin-Madison says the cows were poisoned by a toxin found in moldy sweet potatoes, which “apparently were mixed in with potato waste fed to the animals. Tests on feed samples revealed the presence of ipomeanol, a mycotoxin found in moldy sweet potatoes, says Peter Vanderloo, associate director of the lab.”
The report goes on to say sweet potato waste was a major component of the animals’ diet at the time of the Jan. 14 incident, he notes. It is a common practice in agriculture to feed animals food that cannot be used for human consumption. In this case, the potatoes were never in the human food supply chain, Vanderloo explains, and there is no risk to human heath.
Officials had originally suspected that the steers might have died from a virus or, more recently, pneumonia.
