Fuyu Li - Response to Positive Test
Food Contamination of Clenbuterol may have sidelined the popular Chinese Champion - Expert backs claim of innocence...

Fuyu Li claims innocence, expert says contamination likely
Fuyu Li, the Chinese rider of team RadioShack, who was tested positive at Dwars door Vlaanderen (23rd of March), claims he did not knowingly take any banned substance. Li was tested positive for Clenbuterol.

The value that was found in Li’s sample, is extremely low. Ten to twenty times lower then a WADA/UCI laboratory must be able to detect, according to anti-doping expert Douwe de Boer:

“Laboratories must be able to find 1.00 ng/mL, while a normal threshold value is considered to be 2.00 ng/mL. The value of 0.05-0.10 ng/mL that was found in Fuyu Li’s body points clearly in the direction of a contamination. On top of that, such a low dose would not help his performance in any way.”

“I have no idea how the Clenbuterol came into my body. All I know is that I have never taken doping in my entire career”, said Fuyu Li. “My role at team RadioShack was one of a humble helper, nothing more. I am 31 years old and I know I could not move up to a leading role in the team, I was just extremely honored to be selected for this team and tried to do my job right.

I have won the China Games (the main national sports event in China) a couple of times, which makes me a famous sportsman in China. I have a lot to loose in China and nothing to prove anymore, in my country. There was no incentive for me to do something crazy like taking doping and I did not do that. Not now, not at any other moment in my career.”

Douwe de Boer stated, “The extremely low value points in the direction of a contamination. Clenbuterol contaminations exist in food supplements and in meat. Clenbuterol is often used to improve the visible quality of meat. There have been several scandals in China, with Clenbuterol poisoning of people by eating heavily contaminated meat. My best guess would be that something like this caused Fuyu Li’s positive. I hope he will be treated fairly in his process in China.

Doping rules are saying that a rider himself is held responsible for irregularities in his body. It will be hard if not impossible to really prove how he did get the Clenbuterol in his urine, though. Again, the poor food safety in China would be my best educated guess.”

Douwe de Boer is a Senior Investigator and Biochemist at the University Hospital Maastricht, the Netherlands and former director of WADA anti-doping laboratory Lisbon, Portugal.

Clenbuterol Poisoning
Over 330 Shanghai residents have been poisoned by pork tainted with a weight-loss steroid popular among bodybuilders. As a result, a total of 336 people have been poisoned in Shanghai since September 13, in the city's largest Clenbuterol poisoning case, the paper said.

The chemical can reportedly cause damage to the human nervous and cardiovascular system. However, all those affected in Shanghai have been released from hospital, the paper said.

Most of the pigs have been traced to neighboring Zhejiang where rearing pigs on clenbuterol, known locally as "lean meat powder", is widespread, the paper said.

At least 70 people in one Chinese province have suffered food poisoning in recent days after eating pig organs contaminated by a banned food additive, state-run media reported Monday.

Three people were detained for suspected involvement in raising and selling contaminated pigs, authorities said.

Clenbuterol can prevent pigs from accumulating fat but is harmful to humans and can be fatal. One of the largest food poisoning cases involving clenbuterol happened in Shanghai in September 2006, when 336 people were hospitalized after eating pig meat or organs contaminated with the additive, China Daily said.
