Poultry market tests spark flu advisory

Consumers in Guangzhou, Guangdong province, are being urged to avoid contact with live poultry after tests found that more than 30 percent of live poultry markets in the city were contaminated with the H7N9 avian flu virus, according to Guangzhou's disease control authority.

Health experts have called for stricter measures to contain the virus to prevent possible outbreaks.

Zhang Zhoubin, deputy director of the Guangzhou Center for Disease Control and Prevention, said surveillance reports in the past week show that the H7N9 virus exists in about 30 percent of the city's farmers markets that sell live poultry.
