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
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.”

Hospital Maastricht, the Netherlands and former director of WADA anti-doping

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

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.
