Adoption of HPAI biosecurity measures：The Chinese broiler industry

摘要

Highly pathogenic avian inlfuenza (HPAI) contaminationvia wild birds and rodents poses a threat to food security and safety. As chicken meat comprises an increasing proportion of diet in China, it is useful to determine whether broiler farmers are adopting wild bird and rodent controls to minimize the risk of HPAI impacts on food supply. Our study surveyed a cross sectional sample of 331 Chinese broiler farmers in six provinces. We ifnd that only 47% of farmers (mainly farmers with large herds) adopted control measures against wild birds and rodents, while 14% adopted no measures. Farm size was the biggest driver of adoption folowed by proportion of farm revenue derived from broiler production. However, southern farmers were at a far greater probability of non-adoption. We suggest that assistance in the form of education/training programs and subsidized traps or baiting controls across smaler producers could help raise of the adoption level toward more effective HPAI control.
