The World Anti-Doping Agency is to conduct an audit of the Jamaican Anti-Doping Commission (JADCO), amid claims that the country's top athletes were not tested in the lead-up to the London 2012 Olympic Games.
In August, Renee Anne Shirley, the former executive director of JADCO, claimed there was a near complete breakdown in the organisation's out-of-competition testing between January and July 2012.
While JADCO chairman Herbert Elliott dismissed Shirley’s figures, WADA told AP today there was, as Shirley claimed, "a significant gap of no testing" by JADCO as athletes trained for the Olympics.
David Howman, director general of WADA, said: "There was a period of, and forgive me if I don't have the number of months right, maybe five to six months during the beginning part of 2012 where there was no effective operation. So we were worried about it, obviously."
Howman said it was now a major priority of WADA to focus on the lack of out-of-competition testing carried out by JADCO.
However, Jamaican athletes such as star sprinter Usain Bolt did not go completely untested in the run-up to the games as the IAAF, track and field's international governing body, claims that its own out-of-competition programme was "robust and comprehensive", with tests carried out at training camps.
In addition, all athletes finishing in the top five places at London 2012 were tested by the International Olympic Committee. Jamaican sprinters won eight medals in London, with Bolt striking gold in the 100 metres, 200 metres and the 4x100 metres relay.
Earlier this year, high-profile Jamaican athletes including Asafa Powell, Sherone Simpson and Veronica Campbell-Brown failed drugs tests, and subsequently missed the 2013 IAAF World Championships in Moscow.
