Over 300 people in Shanghai were hospitalized complaining of dizziness, fatigue, tachycardia, and muscle spasms after consuming pork from pigs fed Clenbuterol.
Although banned by Chinese officials in the 1990s, the practice of feeding pigs the steroid, known locally as "lean meat powder", to produce leaner pork is reportedly widespread. Farmers stop feeding the drug several weeks before slaughter.
Most of the people affected were treated and released although about a dozen were hospitalized for further observation. The drug, prescribed to treat respiratory diseases such as asthma, is often abused by athletes or as a weight-loss supplement and can cause damage to the human nervous and cardiovascular systems.
