"The integrity of our testing programme has been proved and, therefore, this is just something we are going to strengthen. 

"Work is being done to get outside assistance to see not just how we can not just strengthen the work of JADCO but raise the bar in terms of their professional activities and efficiency.

"All of this is being done."

Fennell claimed it was wrong that doubts were being cast over Bolt and other top Jamaican sprinters, who finished third overall in the medals at this year's International Association of Athletics Federations (IAAF) World Championships in Moscow with six gold medals. 

"All our top international stars are continuously being tested because they are in the registered testing pool of the international federation," he said.

"The IAAF have confirmed that they athletes have been tested regularly and continuously."

There had been new doubt cast over Jamaica's anti-programme earlier this week when Dr Paul Wright, JADCO's senior doping control officer, had told the BBC in an interview that the doping problems the country is currently experiencing could be just the "tip of the iceberg".

It followed comments made earlier this year to American magaizine Sports Illustrated by JADCO's former executive director Renee Anne Shirley that the agency conducted just one out-of-competition test in the six months leading up to London 2012.

Jamaica's Sports Minister Natalie Neita-Headley defended her country's anti-doping programme but did acknowledge there were some areas they could improve.

"We do have some weaknesses and we will work towards strengthening them and ensuring that where there are gaps we will fill them," she told insidethegames.

But she claimed people were forgetting that Jamaica's Olympic heritage stretched back to London 1948 when they made their debut in the Games and won three medals, including a gold for Arthur Wint in the 400 metres

"We have a long and illustrious history of success in sport," Neita-Headley

"It's not an overnight thing.

"There is no-one who is familiar with athletics who can say that Jamaica has only come onto the world [stage] in recent times.

"Those who understand the process would know we have an institutionalised system in Jamaica that allows us to continue to produce good athletes who are keen on not cheating."

Neita-Headley claimed that a spate of recent high-profile positive drug cases, including former world 100m record holder Asafa Powell, were as the result of "accidental" doping.

"I believe we have had some unfortunate incidents with supplements," she said.

"We have a duty of education that will need to be ramped up in the near future."
