Objective To understand the occurrence and distribution of Campylobacter jejuni in chicken in China, assess its health risk to the Chinese population, and provide recommendations for effective risk control. Methods Data from the National Food Safety Risk Surveillance Network on Campylobacter jejuni between 2007 and 2010 and from published articles were analyzed. Eleven parameters were used based on the whole chicken preparation process and prevalence of Campylobocter jejuni for risk assessment by using the Ross-Sumner Method. Results The detection rates of Campylobacterjejuni in raw chicken were between 0.29% and 2.28% during 2007-2010 in China （more than 20 provinces）. The probability of illness caused by Campylobacter jejuni due to chicken consumption was around six out of one million consumers per day in urban areas and around one out of one million consumers per day in rural areas. Total predicted illnesses per year was about 736 000, accounting for 1.6‰ of the general population in urban areas and about 301 000, accounting for 0.37‰ of the total population in rural areas. The risk rankings of Campylobocterjejuni in chicken were 52 and 49 in urban and rural areas, respectively. Conclusion A high risk score for Campylobacterjejuni in chicken was obtained in China. This result may contribute to development of food safety management strategies. Key efforts should be made to control the risk of Campylobacterjejuni in chicken in China, especially in chick breeding and chicken preparation processes.
