Alberto Contador Has Done Something Lance Armstrong Never Did

He has tested positive for a banned substance during the Tour de France (see here). The substance is clenbuterol, an asthma medication that is also a strong stimulant. It is banned in the United States, but used widely in Europe. It remains to be seen whether Contador will be stripped of his title, as Floyd Landis was a few years ago.So far, his defense is food contamination, which is a plausible excuse. Clenbuterol has been known to get into the food supply through livestock. In 2006, more than 300 people in China were sickened by pork contaminated with clenbuterol.  At the very least, however, Contador will have to explain just what it was he ate in the day or two before testing positive that might have been contaminated, which no other tested rider ate.

UPDATE: Cyclingnews is reporting (here) that levels of clenbuterol levels found in Contador's blood were extremely low, which might support his defense.
"The concentration found by the laboratory was estimated at 50 picograms (or 0,000 000 000 05 grams per ml) which is 400 time less than what the antidoping laboratories accredited by WADA must be able to detect,” said the UCI release.

The Cologne, Germany, laboratory that tested Contador’s July 21 sample is known for being one of the worlds’ most advanced for clenbuterol detection. Had Contador’s sample been tested anywhere else the traces are so minute that the substance would likely have been undetected.

    See comment about autologous blood doping. Makes much more sense to me....
