The objective of this meta-analysis was to summarize available information on the prevalence ofthermotolerant Campylobacter in different animal food products. A number of multilevel randomeffectmeta-analysis models were fitted to estimate mean prevalence of thermotolerantCampylobacter 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% CI27.6% - 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 (pestimate=47.8%; 95% CI 44.9% - 50.6%). C. jejuni was mainly observed in broiler meat whereprevalence estimate (p-estimate) was 33.7% (95% CI 30.7% - 36.8%). On the other hand, C. coliwas observed in broiler meat (p-estimate= 14.1%; 95% CI 12.3% - 16.1%) and sheep meat (pestimate=11.0%; 95% CI 3.6% - 29.1%). The animal food products with the lowest prevalence ofCampylobacter 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 broilermeat is the main contamination source for human. The prevalence of Campylobacter species haspublic health importance and national authorities must monitor the situation in each country withthe aim to establish the appropriate risk management measures
