PARIS - Australian rider Michael Rogers has blamed a positive test for the banned substance clenbuterol on food contamination, saying on Friday he never intentionally ingested the banned anabolic agent. “I would like to make it very clear, in the strongest terms possible that I have never knowingly or deliberately ingested clenbuterol,” the Saxo-Tinkoff rider, who failed the test at the Japan Cup on Oct 20, said in a statement. “I can advise that during the period 8th-17th of October, before arriving in Japan, I was present in China for the World Tour race, Tour of Beijing. “I understand that it has been acknowledged by the World Anti-Doping Agency (WADA) as well as other anti-doping bodies, that food contaminated with clenbuterol is a serious problem in China.”–Reuters
