A pool of disinfectant has collected at the gate to the Guangzhou Kwangfeng Industrial Company where vehicles are hosed down before being allowed to enter. Those entering on foot pass along a 20-metre corridor covered by gunny sacks soaked in disinfectant that leads to the staff living quarters. Further away, an iron gate closes off an inner compound where chickens are raised. Only staff are allowed to enter this inner sanctum and only after they have showered, washed their hair and changed their clothes and shoes. 'Our workers and technical experts go in twice a day and each time they have to go through the disinfection process,' said a management spokesman. 'The rest of us are confined to this living area and we are allowed to leave the farm only once a month.' The farm supplies 1.5 million live chickens and several hundred thousand frozen birds to Hong Kong each year. Employees are quarantined in its living quarters for two days each time they leave the farm before they can re-enter the chicken area. Despite the quarantine measures, the farm's deputy manager, Zeng Xianjun, is worried about bird flu. 'Vaccines are not enough. We have to make sure that conditions are clean. 'We are worried because there will be no market for our chickens. Even though we have a lot of experience, we are still worried about diseases.' Mr Zeng was breaking quarantine rules by giving an interview to reporters who had let themselves into the staff quarters and refused to leave. Other managers at the company said the provincial quarantine department had barred them from talking to reporters at the farm without its approval. But for all its concern, the bureau has not yet sent anyone to the farm to inspect conditions since the outbreak in neighbouring areas.
