To fight the spread of mad cow disease, the U.S government is now barring the sale of meat from cows that are too sick to walk or stand. This comes just weeks after Republican congressional leaders rejected a similar ban after it came under pressure from the meat industry. The Food and Drug Administration also announced a bar food manufacturers using the small intestine from cattle in food for humans. A total of 32 countries have been banned the importation of US beef since last week when the government announced the discovering of a cow suffering from mad cow disease.
