South Korea has said it will likely soon permit some level of the animal feed additive zilpaterol in beef, easing its zero-tolerance policy.
After two shipments of beef contain a trace of zilpaterol was found, South Korea suspended some U.S. beef imports.
A director in South Korea's food ministry, Son Seong-wan, told Reuters, South Korea will allow 1 part per billion (ppb) of zilpaterol in beef muscle and 5 ppb in beef liver.
Currently, the country is completing a 60 days hearing process on the policy change. The change is anticipated to go in effect in June.
Zilpaterol is a beta agonist sold under the trade name of Zilmax.
