DES MOINES, Iowa (AP) — Animal scientist Temple Grandin has criticized legislation that restricts or bans underground videos in feedlots and confinements. The Des Moines Register reports the animal rights authority told the Iowa Farm Bureau Wednesday that laws with such rules are “the dumbest thing.”

The newspaper reports that Gradin also praised beef trimmings, or so-called “pink slime” as a good product. She says its production should never have been suspended. The product is the subject of a lawsuit by Beef Products Incorporated in South Dakota against ABC News. Grandin also spoke against sow gestation crates, a method of enclosure used in pig farming. It’s a controversial issue between hog producers and animal rights activists.
