In my view the blood transfusion explanation is clearly the most plausible. His whole team would have tested positive if the contaminated meat explanation was correct. Contador's team would not have been able to detect Clenbuterol at that level so they inadvertently created a marker for the blood transfusion to be detected.
A cheating blood transfuser gets busted. Hooray! I just wish they could catch the rest of them. Such a shame that there is such an effective way of cheating that is still largely undetectable (unless the testers get lucky with a trace marker)
