WADA Rejects Contador's 'Contaminated Meat' Defense

The World Anti-Doping Agency has reportedly rejected Alberto Contador's claim that contaminated beef resulted in his failed drug test.  Via the Washington Post:

A Spanish newspaper says the World Anti-Doping Agency found no evidence to support Alberto Contador's claim that contaminated meat caused his positive test at the Tour de France.

El Pais says WADA went to the meathouse in Irun, Spain, that provided the meat that Contador contends led to the positive finding for clenbuterol.

The paper says WADA's own tests showed no signs of the banned drug in the meat.

The paper quotes a leaked WADA report as saying Contador's intake of clenbuterol "could not have come from possibly contaminated meat." It also ruled out asthma medication as a cause.
