The Jamaica Anti-Doping Commission (JADCO) has taken responsibility for Jamaica’s 4 X 100 meters world record at the 49th CARIFTA Games not being ratified by track and field’s world governing body World Athletics.

This after the local anti-doping body opted not to test one member of Jamaica’s world record breaking 4 X 100 meters relay team on the day of the record as the athlete was tested the day before after winning her individual event.

Chairman of the JADCO Alexander Williams says in light of the development the local anti doping body would have to bear some of the responsibility for the rejection of the world record.

While admitting that the athlete should have been tested, the Chairman explained what led to the decision not to test the athlete two days in a row.

Meanwhile former doping control officer and Sports Medicine Specialist Dr. Paul Wright has laid the blame squarely at the feet of JADCO.

The quartet of Serena Cole, Tia and Tina Clayton along with Brianna Lyston clocked a blistering 42.58 seconds to erase the previous mark of 42.94 set also by Jamaica in Nairobi, Kenya at last year’s World Junior Championships.

As a result of the rejection by World Athletics the old mark of 42.94 second remains as the official Under 20 women’s 4×100 metres world record.
