-UCSUSA Over the last 50 years, the way food animals are raised and fed has changed dramatically—to the detriment of both animals and humans.
FORCING OUR ANIMALS TO CANNIBALIZE THEIR OWN KIND:
The advent of "mad cow" disease (also known as bovine spongiform encephalopathy or BSE) raised international concern about the safety of FEEDING RENDERED CATTLE TO CATTLE. Animals in CAFOs are fed food unnatural to their digestive systems: Same Species Meat, Diseased Animals, and Feathers, Hair, Skin, and Blood
Since the discovery of mad cow disease in the United States, the federal government has taken some action to restrict the parts of cattle that can be fed back to cattle.
However, most animals are still allowed to eat meat from their own species. Pig carcasses can be rendered and fed back to pigs, chicken carcasses can be rendered and fed back to chickens, and turkey carcasses can be rendered and fed back to turkeys. Even cattle can still be fed cow blood and some other cow parts.
Under current law, pigs, chickens, and turkeys that have been fed rendered cattle can be rendered and fed back to cattle—a loophole that may allow mad cow agents to infect healthy cattle.-▶ MAMMARY TUMORS, KIDNEY AND LIVER DAMAGE IN RATS FED GMO CORN IN FIRST EVER LONG-TERM STUDY http://www.scoop.it/t/agriculture-gmos-pesticides/p/2738034736/mammary-tumors-kidney-and-liver-damage-in-rats-fed-gmo-corn-in-first-ever-long-term-study The Ecologist, November 28, 2013 -▶ DEFORMITIES, SICKNESS AND LIVESTOCK DEATHS: THE REAL COST OF GENTICALLY MODIFIED ANIMAL FEED http://www.theecologist.org/News/news_analysis/2176082/deformities_sickness_and_livestock_deaths_the_real_cost_of_gm_animal_feed.html
