Humans must guard against animal disease risk

　　Peter Ben Embarek, food safety officer at WHO's China office, said the country faces risks connected to the need to produce more meat, eggs and milk to feed its growing population. He said the increased production will ramp² up the risk of people being infected by food-borne diseases because of poor slaughtering⁴ oversight⁵ and the absence of proper surveillance and inspection⁶ systems.

　　About 50 percent of pigs in China are slaughtered⁷ outside of formal facilities without the inspection of veterinarians or food safety officers. He said poorly trained producers have little or no awareness⁸ of food safety or the risk of animal diseases being passed on to humans.

　　Such an environment could lead to the emergence⁹ of a new pandemic of influenza¹⁰.

　　During the past 60 years, 30 percent of the 335 new infectious diseases worldwide were transmitted through food, he said.

　　Yet in many parts of China, public awareness remains¹¹ low about such things.

　　Xu Aixiang, a 35-year-old resident of Rizhao city in Shandong province, prefers to buy live poultry¹² at local markets. Like many of her neighbors, she takes the chickens she buys home to slaughter³ them.

　　"I get fresher chickens that are better quality this way," she said. "When vendors¹³ sell slaughtered chickens, the meat is no longer fresh and may have had water injected into it to make it heavier."

　　But Ben Embarek cautioned that such live-animal markets are high-risk places for the exchange of viruses and diseases between animals and humans.

　　He said simple and cost-effective measures can be taken to improve such markets' hygiene¹⁴ standards, such as the installation of separate areas to keep live poultry away from customers as well as improving air flow and waste management.

　　Several UN agencies, including the WHO and the Food and Agriculture Organization, called on China to adopt an integrated approach to preventing emerging epidemic¹⁵ diseases and maintaining ecosystem¹⁶ integrity at an event themed "One Health" that convened¹⁷ on Wednesday in Beijing.

　　At the gathering¹⁸, representatives from the Ministry¹⁹ of Health, the Ministry of Agriculture and the Chinese Center for Disease Control and Prevention shared experiences from efforts to mitigate²⁰ the H5N1 and H1N1 influenza outbreaks in China and said they were committed to working together in the future.

　　Su Jingliang, an associate professor of preventive veterinary medicine at China Agricultural University, said his lab had detected the outbreak of a new type of flavivirus in ducks that led to a significant fall in egg production at farms in Beijing as well as in Hebei, Jiangxi and Shandong provinces. The pandemic was brought under control in March.

　　No cases of humans contracting the disease have been reported so far but Su said he was concerned about the possibility of farmers becoming infected through close contact and long exposure to sick ducks.

　　He said precautionary measures should be taken in cooperation with the Ministry of Health and other government agencies and checks should be run on people who are at high risk.
