Arizona Tribune - Three swimmers in China doping scandal failed earlier tests: report

The Times said the three athletes -- including two 2021 Olympic gold medallists and a current world record holder -- tested positive for clenbuterol in 2016 and 2017.

Chinese authorities argued the three athletes had ingested the substance inadvertently through contaminated meat, and no disciplinary action was taken.

The World Anti-Doping Agency (WADA), said in a statement released on Friday that the three athletes in question were found to have levels of clenbuterol which were between "six and 50 times lower" than the minimum reporting level currently used by the agency.

Swimming's international governing body was made aware of the cases and did not take action after apparently accepting the explanation, the Times reported.

WADA director general Olivier Niggli said in a statement the case highlighted the problem of clenbuterol contamination in meat.

"The issue of contamination is real and well-known by the anti-doping community," Niggli said.

"Over the years, there have been thousands of confirmed cases of contamination in its various forms, including more than 1,000 for meat contamination in Mexico, China, Guatemala, Colombia, Peru, Ecuador and other countries.

"The athletes in question were three such cases. They were elite level swimmers who were tested on a very frequent basis in a country where meat contamination with clenbuterol is widespread so it is hardly surprising that they could be among the hundreds of athletes who also tested positive for tiny amounts of the substance.

"In each of these cases, the source of the clenbuterol was confirmed to be food contamination."

It was not made immediately clear why the three cases were not made public at the time.

- 'Zero confidence' -

The latest revelations come after the sporting world was rocked by reports in April which revealed that 23 Chinese swimmers had tested positive for a prescription heart drug, trimetazidine (TMZ), ahead of the pandemic-delayed 2021 Tokyo Olympics.

Chinese authorities said the athletes had ingested the substance unwittingly through contaminated food.

The United States Anti-Doping Agency (USADA) said WADA and China's anti-doping body had "swept those positives under the carpet", describing the case as a "potential cover-up."

WADA responded furiously to those accusations, insisting the case had been handled according to existing protocols and denying claims of a cover-up.

Yet the fresh revelations reported by the New York Times brought more barbed criticism of WADA on Friday by USADA and Global Athlete, the body which works on behalf of athletes worldwide.

"Unbelievable does not seem fitting enough for the (New York Times) report from today about WADA once again allowing China to sweep positive tests under the carpet," USADA chief executive Travis Tygart said in a statement emailed to AFP.

"Athletes from around the world were held accountable to the rules in effect at the time but now the world learns that WADA allowed special treatment for a chosen few. How far and wide does this preferential treatment go?

"How many other countries or sports were given favorable treatment by WADA and allowed to circumvent the rules that apply to everyone else?"

Global Athlete chief Rob Koehler said athletes had "zero confidence" in WADA and World Aquatics.

"Athletes are tired of empty statements from WADA that divert from answering hard questions on why all of these cases were not made public," Koehler said.

"Transparency is needed more then ever, without transparency the anti-doping movement will crumble and athletes will never feel they have a level playing field."
