That video of pigs being fed plastic it is in a facility in North Carolina, USA, run by Smithfield Foods, a Chinese-owned entity, the largest pork producer in the United States.

I have searched for to know what happened with that facility, but the only article that I've been able to find, and that it is showed as first result in the search engine, is from fayobserver[1], labeled as USA Today Network, saying a "do not worry".

Legal or not, it's an outrage. Did the FDA allowed this in the end?

From their web[2] << Headquartered in Smithfield, Virginia, Smithfield Foods is an American food company dedicated to producing Good food. Responsibly.® >>
