Video shot in April at the Wyoming Premium Farms facility in Wheatland shows workers kicking living piglets like soccer balls; swinging sick piglets in circles by their hind legs; striking mother pigs with their fists; and repeatedly and forcefully kicking them as they resisted leaving their young.

A Tyson Foods spokesman denies the company buys directly from the farm:

Tyson Foods does not buy any of the hogs raised on this farm for our pork processing plants. … A company that we own has purchased hogs from the farm. We will not purchase from this farm until we’ve had a chance to investigate.
