In 2015, two players from the Collingwood Football Club in Australia were delisted from the club and accepted two-year bans from all sport in Australia after testing positive to the substance, which they believe may have been in a contaminated illicit drug they consumed. In 2016, Australian heavyweight boxing champion Lucas Browne tested positive for clenbuterol. In 2016, Raul A. Mondesi tested positive for clenbuterol and was suspended 50 games from the Northwest Arkansas Naturals. MLB and the MLBPA agreed to reduce the suspension from 80 games to 50 games after Mondesi claimed it was found in cold medicine. In 2016, the California State Athletic Commission decided to issue Francisco Vargas a temporary boxing license on a probationary basis after he tested positive for clenbuterol. In 2018, British Olympic sprinter Nigel Levine was provisionally suspended for failing a drug test. In March 2018, champion boxer Canelo Alvarez tested positive for clenbuterol on two consecutive urine tests in February 2018. This violation led to the cancellation of a heavily anticipated rematch between Alvarez and Gennady Golovkin, which was to be held on May 5, 2018. Food contamination Clenbuterol is occasionally referred to as "bute" and this risks confusion with phenylbutazone, also called "bute". Phenylbutazone, which is a drug also used with horses, was tested for in the 2013 European meat adulteration scandal. Intended to result in leaner meat with a higher muscle-to-fat ratio, the use of clenbuterol has been banned in meat since 1991 in the US and since 1996 in the European Union. The drug is banned due to health concerns about symptoms noted in consumers. These include increased heart rate, muscular tremors, headaches, nausea, fever, and chills. In several cases in Europe, these adverse symptoms have been temporary. Clenbuterol is a growth-promoting drug in the β agonist class of compounds. It is not licensed for use in China, the United States, or the EU for food-producing animals, but some countries have approved it for animals not used for food, and a few countries have approved it for therapeutic uses in food-producing animals. Not just athletes are affected by contamination. In Portugal, 50 people were reported as affected by clenbuterol in liver and pork between 1998 and 2002, while in 1990, veal liver was suspected of causing clenbuterol poisoning in 22 people in France and 135 people in Spain. In September 2006, some 330 people in Shanghai suffered from food
