USDA Says No Mad Cow Threat, Korean Markets Pull U.S. Beef [VIDEO]

The first case of mad cow disease in the U.S. since 2006 has been discovered.  Back in 2003, the first- ever case in the country, caused a $3 billion dollar plunge in export revenue that took until 2011 to fully recover from. This time, officials say there is no cause for alarm.

The first new case of mad cow disease - and the fourth case here ever - has been discovered in the U.S.  The U.S. Government's Chief Veterinary Officer, Dr. John Clifford:

(Dr. Clifford) "Our laboratory confirmed the findings, and also indicated that it was an atypical form which is a rare form of the disease.  It is not likely to be attributable to infected feed."

The USDA is expected to release more details in the coming weeks tracing the history of the cow, where she was born, what she has eaten and what happened to other cows born on the same farm during the same time period.

The effects of the discovery are being felt.  While no governments have banned the import of U.S. beef, two of the top three supermarket chains in South Korea aren't taking a chance, pulling American beef from their shelves.

South Korean owners of Lotte Mart say they pulled the beef not out of any quality concerns, but because consumers were worried.  British-owned Home Plus, also pulling the product from their shelves.

South Korea's Food Ministry says they're studying whether to halt quarantine inspections.  No inspections would mean no imports.

Before a 2003 ban, South Korea was America's #3 beef market in the world.  When President Lee Myung-bak in 2008 reopened the market to boneless beef from cattle younger than 30 months, anti-U.S. beef protests turned violent.
