Ractopamine is a drug that is used as a feed additive to promote leanness in pigs raised for their meat. The feed additive Paylean, produced by the U.S. company Elanco Animal Health, owned previously by Eli Lilly and Company, contains ractopamine hydrochloride. Paylean was approved by the United States Food and Drug Administration on December 22, 1999, and has also been approved in more than 20 countries, including Australia, Brazil, Canada, Mexico, and Thailand. However it is banned in 150 other countries, including the European Union, China, and Malaysia, which prohibited its use in 2002.
