premise: US Agriculture Secretary Mike Johanns on Sunday voiced satisfaction after Japan gave the final go-ahead to resume imports of some US beef after a two-year ban.
  "I'm very pleased to announce that the Japanese market is now open to US beef products," Johanns said in a statement. "Resuming beef trade with Japan is great news for American producers and Japanese consumers, as well as an important step toward normalized trade based on scientifically sound, internationally recognized standards."
  Japan barred imports of US beef in December 2003 after cases of mad cow disease, formally known as bovine spongiform encephalopathy (BSE), were discovered in cattle in the country.
  It was a devastating blow to the US farming industry as Japan was the number one overseas market for its beef, buying 1.7 billion dollars worth in 2002. Japan had imposed a similar ban on Canadian beef in May 2003.
  The row with Washington turned bitter in October 2004 when Japan promised to exempt US cows aged 20 months or younger from screening if high-risk parts were removed. Washington interpreted the agreement as a breakthrough but Tokyo said it needed more time to verify how to test the age of the cattle.
   What should happen after japan gave the final go ahead?
