Back in December of 2003, the first case of mad cow was reported at a Mabton dairy farm, and what followed took until 2011 before US exports of beef fully recovered. Health officials in California say this animal was never a threat to the nations food supply, but the USDA is tracing the life of the cow. First world wide reaction came from two South Korean retailers who have temporarily suspended sales of US beef. Over all, South Korea imports about 107,000 tons of meat a year, while Japan the 3rd largest consumer of US beef says their import policy is unchanged.Other countries have a wait and see attitude, as USDA continues to investigate.
