On 'Law & Order: SVU' (Wed., 10PM ET on NBC), the team goes undercover to solve a murder that took place in a slaughterhouse. But things start to go badly almost right away. First of all, the slaughterhouse is disgusting -- filled with cockroaches and rat droppings. Still, that isn't the worst part.
