Tour de France winner, Alberto Contador of Astana has tested positive to clenbuterol and has been suspended by the UCI. Contador has announced that this result from a doping control from 21. July can only possibly be the result of food contamination.
The concentration of clebuterol detected in testing by a Cologne laboratory was announced by the UCI as being a very small concentration – 50 picograms, though both in the A and B blood sample. This amount is 400 times less than the limit that accredited World Anti Doping Agency (WADA) Laboratories need to detect.
Contador will give a press conference today.
Alberto Contador is currently signed to Team Astana as won the Tour de France in 2007, 2009 and 2010. In 2011 he will join the Saxobank team of Bjarne Riis.
