The final regulation will allow for the safe trade of bovines and bovine products, while still protecting the United States from the introduction of BSE.

China and South Africa have halted imports of beef from Brazil following a case of atypical BSE that was confirmed last week.

After it was revealed that a Brazilian cow that died in 2010 contained the proteins linked to BSE, Brazil is working to convince importers that its beef is free of mad cow disease.

The Brazilian government notified the World Animal Health Organization (OIE) of the discovery of the protein believed to cause bovine spongiform encephalopathy (BSE) in a cow that died in 2010.

Despite the discovery of a BSE-infected cow in California, major importers increased their purchases of U.S. beef in the last week.
