In China, several central government departments are involved in quality control, including the Ministry of Agriculture (MOA), responsible for agricultural products, the Ministry of Health, responsible for hygiene, the State Administration for Industry and Commerce (SAIC), which monitors food products in circulation, and the AQSIQ, which oversees the production, processing and export of food, and the SFDA, which is responsible for comprehensive supervision, coordination and food safety crisis management.

The five departments play their roles respectively in the food export process. For example, when a food safety assessment is demanded, the Ministry of Health will organize a team of experts. When it is a problem in the circulation chain, it's the job of the SAIC, and if it's a production and processing problem, the AQSIQ will recall the food and carry out punishments on the manufacturers. The Ministry of Agriculture takes action when the problem is traced back to the planting and cultivation process.

Despite all these efforts in legislation and supervision, it's been a headache for the AQSIQ to see the number of complaints over exported food quality that have come across their desks.

Li Changjiang, head of the AQSIQ, said officials were focusing on stricter market access requirements for companies, conducting random checks and beefing up product testing.

Li said that according to China's Law on Import and Export Commodity Inspection, export commodities subject to compulsory inspection must be inspected by the commodity inspection authorities or inspection organizations. For those not in the list for compulsory inspection, the AQSIQ will conduct random checks and the manufacturers should entrust related inspection organizations with the inspection to ensure their products meet the requirements of importers.

Individual enterprises' failures in this respect have led to the recent quality problems of some of China's exports, said Li.

Yet he stressed that China was not the only one with similar problem, citing comments by World Health Organization Director-General Margaret Chan this week that the agency receives about 200 reports of food safety problems every month from its 193 member states.

Lin of the AQSIQ defended the quality of China's exports, saying that recent problems, including the scare over pet food exported to North America, are only exceptions, often involving unlicensed or illegal companies.

"Investigations have shown these are only individual cases," Lin said at the same press conference. "We have taken tough measures against unlicensed companies which have been the source of such problems."

"No one in the world can ensure zero risk, and similarly, no food is 100 percent qualified," said Li Yuanping. "Problems with a few companies should not be taken to mean that the system as a whole is riddled with holes."

He said such misconceptions have seriously harmed the reputation of Chinese products, are a huge impediment to Chinese exports, and have caused great losses.

Furthermore, in another bid to weed out illegal export companies, the food safety watchdog has published a blacklist of companies that have breached safety rules and regulations on its website and has stripped them of their export rights.

So far, more than 99 percent of Chinese food exports to the United States, in the past three years, have met quality standards. This is about the same, or even higher, than the equivalent figure of U.S. food exports to China, according to Li.
