Between June and September of 2015, an undercover PETA investigation documented how Sweet Stem Farm, a Pennsylvania hog operation, treats its animals. They found “pigs [that] spent almost all their time crammed into crowded sheds on concrete floors,” numerous animals with “grotesque rectal prolapses,” and sick animals left untreated for days on end.

Compared to all the other factory-farm exposés periodically released by animal rights groups, this one was not exceptionally gruesome or violent — Sweet Stem’s abuses seemed almost mundane in comparison.

But this particular investigation didn’t target a big factory farm; it targeted a small operation that touts its “unwavering commitment to the humane treatment of our animals.”
