China's food safety woes now a global concern

updated 3:40 p.m. ET April 12, 2007

SHANGHAI, China - The list of Chinese food exports rejected at American ports reads like a chef’s nightmare: pesticide-laden pea pods, drug-laced catfish, filthy plums and crawfish contaminated with salmonella.

Yet, it took a much more obscure item, contaminated wheat gluten, to focus U.S. public attention on a very real and frightening fact: China’s chronic food safety woes are now an international concern.

In recent weeks, scores of cats and dogs in America have died of kidney failure blamed on eating pet food containing gluten from China that was tainted with melamine, a chemical used in plastics, fertilizers and flame retardants. While humans aren’t believed at risk, the incident has sharpened concerns over China’s food exports and the limited ability of U.S. inspectors to catch problem shipments.

“This really shows the risks of food purity problems combining with international trade,” said Michiel Keyzer, director of the Center for World Food Studies at Amsterdam’s Vrije Universiteit.

Just as with manufactured goods, exports of meat, produce, and processed foods from China have soared in recent years, prompting outcries from foreign farm sectors that are feeling pinched by low Chinese prices.

Worried about losing access to foreign markets and stung by tainted food products scandals at home, China has in recent years tried to improve inspections, with limited success.

The problems the government faces are legion. Pesticides and chemical fertilizers are used in excess to boost yields while harmful antibiotics are widely administered to control disease in seafood and livestock. Rampant industrial pollution risks introducing heavy metals into the food chain.

Farmers have used cancer-causing industrial dye Sudan Red to boost the value of their eggs and fed an asthma medication to pigs to produce leaner meat. In a case that galvanized the public’s and government’s attention, shoddy infant formula with little or no nutritional value has been blamed for causing severe malnutrition in hundreds of babies and killing at least 12.

China’s Health Ministry reported almost 34,000 food-related illnesses in 2005, with spoiled food accounting for the largest number, followed by poisonous plants or animals and use of agricultural chemicals.

Paying the price
With China increasingly intertwined in global trade, Chinese exporters are paying a price for unsafe practices. Excessive antibiotic or pesticide residues have caused bans in Europe and Japan on Chinese shrimp, honey and other products. Hong Kong blocked imports of turbot last year after inspectors found traces of malachite green, a possibly cancer-causing chemical used to treat fungal infections, in some fish.

One source of the problem is China’s fractured farming sector, comprised of small landholdings which make regulation difficult, experts said.

Small farms ship to market with little documentation. Testing of the safety and purity of farm products such as milk is often haphazard, hampered by fuzzy lines of authority among regulators. Only about 6 percent of agricultural products were considered pollution-free in 2005, while safer, better quality food officially stamped as “green” accounts for just 1 percent of the total, according to figures compiled by the U.S. Department of Agriculture.

For foreign importers, the answer is to know your suppliers and test thoroughly, food industry experts said.

“You just have to hope that your system is strong enough and your producers are careful enough,” said Todd Meyer, China director for the U.S. Grains Council.

Health Ministry officials acknowledge problems, but have described scandals such as the 2004 baby formula deaths as isolated incidents. Neither the ministry nor the State Administration of Quality Supervision, Inspection and Quarantine, responsible for overall food safety standards, responded to questions submitted to them in writing as requested.

Over the past 25 years, Chinese agricultural exports to the U.S. surged nearly 20-fold to $2.26 billion last year, led by poultry products, sausage casings, shellfish, spices and apple juice.

Inspectors from the U.S. Food and Drug Administration are able to inspect only a tiny percentage of the millions of shipments that enter the U.S. each year.
