"SACRAMENTO, Calif. -- An undercover video that showed California cows struggling to stand as they were prodded to slaughter by forklifts led to the largest meat recall in U.S. history. In Vermont, a video of veal calves skinned alive and tossed like sacks of potatoes ended with the plant's closure and criminal convictions."

"Now in a pushback led by the meat and poultry industries, state legislators across the country are introducing laws making it harder for animal welfare advocates to investigate cruelty and food safety cases.

Some bills make it illegal to take photographs at a farming operation. Others make it a crime for someone such as an animal welfare advocate to lie on an application to get a job at a plant."
