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. The Guangzhou government had decided to suspend live poultry trade in all markets from Jan 16 to 18, Feb 16 to 18 and March 16 to 18 as a preventive measure to curb bird flu virus.An assessment report shows that the three-day trade halt in January helped reduce all types of bird flu virus at these markets by at least 60 percent.continue
