200 Dead Cows

It had somehow escaped my notice, but 200 dead cows showed up in a Wisconsin pasture 2 weeks ago. I believe it was aliens. But scientists have their own opinions:

Investigators from the University of Wisconsin have determined that the animals were killed by a poison found in spoiled sweet potatoes that were part of the cattle's feed.

The researcher mentioned a "mycotoxin" from the moldy vegetables.

Do not feed your oxen
deadly mycotoxin!
