Shocking : Mercy For Animals Footage Shows Inside One Of Nation's Largest Pork Producers (GRAPHIC) Video

An animal welfare group that has used undercover videos to generate public outrage over the treatment of livestock said it now plans to use secret recordings to pressure large grocery chains to stop buying from farms that use practices it considers abusive.

The effort seemed to be working as several chains viewed the video and then either halted purchases from the targeted Iowa hog farm or expressed concern even before Chicago-based Mercy for Animals formally unveiled the recording at news conferences planned Wednesday in four cities.

Earlier this week, Mercy for Animals met with or sent letters to officials at Costco, Hy-Vee, Kroger and Safeway and provided links to its 2 1/2-minute video, then asked them to stop buying pork from Iowa Select Farms. The group said it secretly recorded its video between April and June at an Iowa Select Farms operation in the small town of Kamrar, about 50 miles north of Des Moines.

Nathan Runkle, Mercy for Animal's executive director, said his group and others have used secretly recorded videos to raise public awareness, but this was among the first major efforts to use such recordings to pressure retailers. The group previously used another video to convince Costco to change its policies dealing with veal obtained from an Ohio producer, he said.

Mountain Lion Declared Gone From East U.S.|Eastern Cougar Extinct

Wednesday declared the eastern cougar to be extinct, confirming a widely held belief among wildlife biologists that native populations of the big cat were wiped out by man a century ago.

After a lengthy review, federal officials concluded there are no breeding populations of cougars – also known as pumas, panthers, mountain lions and catamounts – in the eastern United States. Researchers believe the eastern cougar subspecies has probably been extinct since the 1930s.

Wednesday's declaration paves the way for the eastern cougar to be removed from the endangered species list, where it was placed in 1973. The agency's decision to declare the eastern cougar extinct does not affect the status of the Florida panther, another endangered wildcat.

Ray Sedorchuk, 45, an avid hunter and outdoorsman, said he got an excellent look at a cougar last June in rural Bradford County, in northern Pennsylvania. He was in his truck when a reddish-brown animal with a long tail crossed the road. He said he jammed on the brakes, and the cougar stopped in its tracks.

"I could see the body, the tail and the head, the entire animal, perfectly. It's not a bobcat, it's not a housecat, it's a cougar," he said. "It's a sleek animal. It ran low to the ground and stealth-like. It moved with elegance."

Sedorchuk, a freelance writer who spends copious amounts of time in the woods, said he'd always been skeptical of the eastern cougar's existence, even as two of his friends insisted to him that they had seen them in the wild.
