"The UCI (International Cycling Union) told me of the appearance of the sample on the afternoon of August 24, on the 26th I met the UCI medical team and I explained what had happened. The UCI confirmed that it was a case of contaminated food," he said.

Contador explained how the food in question was some meat that Lopez Cerron, (the director of the cycling Tour of Castilla and Leon) had taken to France.

"He was coming to the Tour and asked if he could bring us something and the team cook, asked him to bring some really good meat. Lopez Cerron bought it in a shop in Spain, although I don't know exactly where, and on the afternoon of July 20 the meat was cooked in the team bus. We ate the meat and on the following day, the rest day, I had a blood test. Then we ate more of the meat and hours later I had a urine test; that is the day they detected the substance," he explained.

Contador also questioned the testing system and added that the minute levels that had been found in his urine were not enough to improve performance, before showing his annoyance at having to explain himself.

"I am sad and disappointed, but I can keep my head high, because you can speak loud and clear when you say the truth. I am not worried that my results will be doubted. I can defend myself pointing to all of the controls I have passed through."

"I am confident the UCI can clearly see what happened, but I would not tolerate a sanction," he said.
