New Zealand's campylobacteriosis epidemic reached a new peak in May 2006 with the annualised national notification rate exceeding 400 per 100,000 for the first time, the highest national rate reported in the literature. The epidemic is estimated to cause at least 1 fatality a year, >800 hospitalisations, and >100,000 cases in the community, and cost the New Zealand economy 75 million dollars per annum. There is overwhelming epidemiological and laboratory evidence that fresh chicken is the dominant source of human infection. The seriousness of this epidemic justifies rapid, decisive action to reduce human exposure to this pathogen. There is good international evidence to support removal of fresh chicken from the food supply, with its reintroduction only when it can be shown to pose a very low risk to human health. Because freezing can substantially reduce Campylobacter levels, frozen chicken could be substituted to allow continued consumption of this popular food. Efforts to reduce Campylobacter colonisation of poultry flocks and contamination during chicken processing and distribution, along with continued consumer education, are important, but do not appear sufficient to control this epidemic in the short to medium term.
2006年5月,新西兰弯曲杆菌病疫情达到新高峰,全国年化通报率首次超过每10万人400例,是文献报道中的最高全国发病率。据估计,该疫情每年至少导致1人死亡、800多人住院以及社区中超过10万例病例,给新西兰经济每年造成7500万美元损失。有压倒性的流行病学和实验室证据表明,新鲜鸡肉是人类感染的主要来源。此次疫情的严重性表明需要迅速采取果断行动,减少人类接触这种病原体。有充分的国际证据支持从食品供应中去除新鲜鸡肉,只有在证明其对人类健康风险极低时才重新引入。由于冷冻可大幅降低弯曲杆菌水平,可用冷冻鸡肉替代,以便人们继续食用这种受欢迎的食品。减少家禽群中弯曲杆菌定植以及鸡肉加工和分销过程中的污染,同时持续开展消费者教育,这些努力很重要,但在短期至中期内似乎不足以控制疫情。
