China Rejects U.S., Canadian Pork

Growth stimulant ractopamine found in more than 40 tons of pork.

BEIJING — China said it had sent back meat imported from the United States and Canada because it contained traces of a banned drug.

Food safety authorities returned more than 40 tons of pork imported from the two countries after discovering traces of the growth stimulant ractopamine, China's official Xinhua news agency said.

Most countries ban the use of ractopamine in livestock destined for human consumption, but it is permitted in 24 countries including the U.S. and Canada, Xinhua said.

China complained last month of problems with food imports from the U.S. and urged authorities there to act to resolve them.
