As producer of one third of the world's vegetable exports, China
was expected to vastly expand its markets once it entered the World Trade
Organization
in December 2001. However, the exceedingly high levels of pesticide
residues in Chinese food products may pose significant problems for
international sales, especially in Europe, Japan and the U.S.,
where food safety standards are more stringent and more strictly enforced.
For example, in
2001, new European Union (EU) regulations reduced pesticide
tolerances for tea by 100 times, effectively excluding half of China's
tea exports to the
EU. This rejection caused more than $125 million in losses to
farmers in Zhejiang Province.
Several reports in the past year illustrate the magnitude of pesticide residues in vegetables grown in China:
**Experts in Yunnan province found that residues of two highly
toxic pesticides--banned by the government for use in vegetable production--were
present in 34% to 100% of vegetable samples taken in Kunming
and Baoshan prefectures from 1994 to 200l.
**In 2001, the Chinese government found 47% of domestically produced vegetables had pesticide residues in excess of government standards.
**The Japanese Ministry of Health found pesticide residues in
some vegetables imported from China that were four times higher than the
agreed-upon
limits.
Pesticide production in China is also on the rise. In 2001, production
rose by 9% to 696,400 tons, more than three times the 1995 total. This
growth
occurred in spite of the government's plans to cut pesticide
production by 2005. Product quality control and distribution are also problematic.
As much
as 40% of pesticides on the market in China are sold under false
brand names, and in Yunnan province, a 2002 study for the Global Greengrants
Fund
revealed that at least half of pesticide distributors are not
legally registered or licensed.
Figures of pesticide poisonings in China are disturbingly high
and are probably underestimated. The Chinese government estimates that
each year
53,300 to 123,000 people are made ill from pesticides, and 300
to 500 farmers die from pesticide exposure. Localized studies have shown
much higher
poisoning rates. More than 20% of farming households reported
some pesticide poisoning in their homes in a 2001 survey of two small agricultural
communities in rural Sichuan conducted by PANNA and the Kunming
Center for Community Development. Medical studies of rice farmers in
Zhejiang found pesticide poisoning in the liver (22%), in the
kidneys (23%), and nerves (6%) of farmers, and also found a relationship
between degree
of liver function abnormality and amount of pesticide used.
Other experts report that more than 100 farmers die of pesticide poisoning
each year in
Yunnan Province alone.
Consumers who may eat contaminated fruits and vegetables are
also at risk for pesticide poisoning, and this type of poisoning may also
be fatal.
Xinping County Hospital in Yunnan province reported 53 such
deaths in the year 2000. Direct consumption of pesticides is still a common
method of
deliberate poisoning and suicide in China, as in the case reported
in 2002, of a snack shop owner who admitted to poisoning his competitor's
customers by putting rat poison in their breakfasts.
