There were a number of mass animal deaths to start the year 2011.  Red Winged Black Birds were falling from the sky, fish were washing up on riverbanks, and 200 cows were found dead on a farm in Wisconsin.  But now, investigators from the University of Wisconsin may have come up with the culprit that killed the cows.

If you're saying, "Wait...so it's NOT the end of the world?"  Then you can rest easy.  At least for now, there may be a different reason for 200 cows to have mysteriously died on a farm in Stockton, Wisconsin.

It is likely that a mycotoxin from moldy sweet potato was a major factor in the disease and deaths of these steers," said Peter Vanderloo, associate director of the Wisconsin Veterinary Diagnostic Laboratory.

Sweet potatoes.  The cows died from eating sweet potatoes.  But kids, you won't get away with telling your parents that you can't eat yours because  the toxic sweet potatoes were not in the human food supply chain, so there was no threat to people.  You're perfectly safe to go on eating your vegetables.  Sorry...

But what about the fish and the birds?  Check out this article from AOL News for theories on why they may have died.

So again....it's NOT the end of the world?
