Abstract: Objective To establish a cockroach risk assessment system for key industries during large scale events by risk recognition and evaluation methods, and to apply the system for the cockroach risk assessment in key industries during the Seventh National Intercity Games in Nanchang, China. Methods The probabilities of cockroach infestation were qualitatively or quantitatively defined, and the risk indices for infestation in key industries were determined according to AS/NZS4360:2004 risk assessment matrix. Results Ten key industries were evaluated for the risk of cockroach infestation. Three industries had grade A probability of infestation, 7 industries had grade B probability, and 1 industry had grade C probability; restaurants had grade 3 outcome of infestation, farmer’s markets, teahouses, and night clubs had grade 1 outcome, and the other 6 sectors had grade 2 outcome. According to the risk indices in key industries, restaurants had an extremely high-level risk (E) of infestation, hospital, teahouses, and night clubs had a medium-level risk (M), and the other 7 sectors had a high-level risk (H). Conclusion By establishing the cockroach risk assessment system for key industries, the biohazards of cockroaches in key industries can be predicted. Not only can this system play a good role in early warning, but it can also help us take specific prevention and control measures in the industries with different risk levels.

摘要： 目的 应用风险识别与风险评估方法,建立大型活动重点行业蜚蠊风险评估体系,并运用该体系对南昌市第七届城市运动会期间重点行业蜚蠊风险进行评估。方法 采用风险评估指数矩阵法,首先对蜚蠊危害风险发生的可能性进行定性或定量定义,并根据AS/NZS4360:2004矩阵评估指数表中相对应的情况确定重点行业风险事故的风险指数。结果 南昌市10个重点行业,风险发生可能性为A级的有3个行业,B级的有7个行业,C级的有1个行业。风险等级划分餐饮业为3级,农贸市场、茶座和歌舞厅为1级,其他6个行业为2级。重点行业风险事故的风险指数,餐饮业存在极严重风险(E),医院、茶座和歌舞厅存在中等危险度风险(M),其他7个行业存在高危险度风险(H)。结论 建立重点行业蜚蠊风险评估体系,可预测重点行业蜚蠊侵害带来的生物风险,不仅能起到很好的预警预报作用,还可以指导不同风险水平的行业采取有针对性的防控措施。
