Live-chicken wholesalers and retailers yesterday won an extra 24 hours to sell off their stock as no new suspected cases of bird flu had been reported. Hong Kong Live Poultry Wholesalers' Association president Tsui Ming-tuen said yesterday government vets had reported no dead chickens or abnormalities among the flock at the Cheung Sha Wan Temporary Wholesale Poultry Market. Mr Tsui said there were 22,000 chickens left unsold in the Cheung Sha Wan market, adding that the authorities had agreed to defer the cleaning days by 24 hours to allow all the stock to be sold. Originally, operations at the market were to be suspended from 9am yesterday until tomorrow. He said the retail sector also had its rest day deferred by 24 hours. Hong Kong, Kowloon and New Territories Poultry Wholesalers and Retailers Association president Wong Wai-chuen said many retailers complained about the imposition of the extra cleaning day, just a week after the compulsory monthly cleaning day, as only a few birds on some small farms had been hit by the virus. 'Given that there are 100,000 to 200,000 chickens at the retail outlets which have to be slaughtered as well, I feel it is both unfair and unjust,' said Mr Wong, who estimated the losses for the retailers to be more than $1 million. At Kowloon City Market, one trader said he only managed to sell three chickens yesterday morning, compared to about 20 normally. Meanwhile, Agriculture, Fisheries and Conservation Department staff have checked farms in the Ta Kwu Ling area and found no irregularities. About 16,000 chickens at one of the farms were culled on Saturday after more than 1,000 of them died mysteriously and initial tests revealed 12 of the birds had the H5 virus. Kwok Ming-cheung, a Kam Tin poultry farmer, said although the operators had adopted a series of preventive measures, their fears had not been allayed. Mr Kwok, who is also spokesman for the New Territories Chicken Breeders, urged the government to vaccinate all 150 chicken farms in Hong Kong. Only chickens in half of them, mainly in Lau Fau Shan and Yuen Long, had been vaccinated, Mr Kwok said. 'The germs are floating around in the air all the time and it is impossible to avoid infection completely. Hence, vaccination will be an effective preventive measure,' he said.
