London – Britain is warning athletes coming to the 2012 London Olympics that eating large quantities of liver can raise the risk of testing positive for clenbuterol.
The official advice comes after the World Anti-Doping Agency issued a warning last month about the dangers of athletes eating contaminated meat.
Clenbuterol is on Wada's list of banned substances as an anabolic agent that builds muscle and burns fat, and athletes who test positive can face bans of up to two years.
In advice based on evidence from the Food Standards Agency, U.K. Anti-Doping warns: “Athletes should be wary of consuming large quantities of liver.”
The British risk assessment is based on eating bovine liver, one of the organs where the highest concentration of clenbuterol lingers. – Sapa-AP
