The objective of this meta-analysis was to summarize available information on the prevalence of thermotolerant Campylobacter in different animal food products. A number of multilevel random-effect meta-analysis models were fitted to estimate mean prevalence of thermotolerant Campylobacter and to compare them among animal food products (cattle, pigs, broiler, hen, goat, sheep). The mean prevalence of Campylobacter spp. in animal food products was 29.6% (95% CI 27.6%–31%), and the mean prevalence of C. jejuni and C. coli were 19.3% and 9.7%, respectively. The prevalence of Campylobacter spp. was higher in products whose sources were broiler meat (p-estimate = 47.8%; 95% CI 44.9%–50.6%). C. jejuni was mainly observed in broiler meat where prevalence estimate (p-estimate) was 33.7% (95% CI 30.7%–36.8%). On the other hand, C. coli was observed in broiler meat (p-estimate = 14.1%; 95% CI 12.3%–16.1%) and sheep meat (p-estimate = 11.0%; 95% CI 3.6%–29.1%). The animal food products with the lowest prevalence of Campylobacter spp. were milk and dairy products (p-estimate = 3.5%; 95% CI 1.8%–6.5%), eggs (p-estimate = 4.0%; 95% CI 1.4%–10.7%), sausage (p-estimate = 9.4%; 95% CI 3.3%–24.0%), This meta-analysis concluding that C. jejuni is the most prevalent species worldwide and broiler meat is the main contamination source for human. The prevalence of Campylobacter species has public health importance and national authorities must monitor the situation in each country with the aim to establish the appropriate risk management measures.

这项荟萃分析的目的是总结各种动物食品中耐热弯曲杆菌的流行情况。拟合了许多多级随机效应荟萃分析模型，以估计耐热弯曲杆菌的平均患病率，并在动物食品（牛，猪，肉鸡，母鸡，山羊，绵羊）之间进行比较。弯曲杆菌属的平均患病率。在动物食品中的比例为29.6％（95％CI为27.6％–31％），空肠弯曲杆菌和大肠杆菌的平均患病率分别为19.3％和9.7％。弯曲杆菌属的流行。肉类产品来源较高的产品（p-估计= 47.8％; 95％CI 44.9％–50.6％）。空肠弯曲杆菌主要在肉类中发现，其患病率估计值（p-估计值）为33.7％（95％CI 30.7％–36.8％）。另一方面，肉鸡（p-估计值= 14.1％； 95％CI 12.3％–16.1％）和羊肉（p-估计值= 11.0％； 95％CI 3.6％–29.1％）中观察到大肠杆菌。 。弯曲菌属菌种患病率最低的动物性食品。分别是牛奶和奶制品（p-估计= 3.5％； 95％CI 1.8％–6.5％），鸡蛋（p-估计= 4.0％; 95％CI 1.4％-10.7％），香肠（p-估计= 9.4％ ； 95％CI 3.3％–24.0％），此荟萃分析得出空肠弯曲杆菌是世界上最流行的物种，而肉类是人类的主要污染源。弯曲杆菌属的流行对公共卫生具有重要意义，国家主管部门必须监测每个国家的状况，以制定适当的风险管理措施。
