The Humane Society says an upcoming Chicago Bull Run needs a license from the U.S. Department of Agriculture, but organizers say otherwise.

The event involves bulls chasing thrill seekers around a fenced track.

The Humane Society contends that organizers do not have a USDA license that ensures the safety of both animals and the public.

John Goodwin is The Humane Society’s Director of Animal Cruelty Policy.

”Why would we put animals in harm’s way when we have more entertainment options available to us today than in any point in human history?” Goodwin said.

Rob Dickens is the co-founder and chief operating officer of The Great Bull Run.

”What happens with this company is that they supply bulls to rodeos,” Dickens said. “They transport bulls all over the U.S. for this purpose and so it’s that country that requires all those licenses by transporting these animals.”

Goodwin says that a lack of license prevents the USDA from inspecting the event.

The Humane Society has called for the USDA to investigate bull runs around the country.
