Investigation of Thermophilic Campylobacter Prevalence in Organic Turkey Farms in Germany
The demand for organic food of animal origin has increased considerahly in recent years.The widespread assumption that the free-range environment contaminates extensively reared turkeys has not heen rigorously tested.The aim of this study is to provide current information about the prevalence of thermophilic Campylobacter in five organic meat producing turkey farms in different regions in Germany as well as on genotypes and possihle sources of contamination.The clinical and environmental samples were identified as Campylobacter by conventional and molecular methods.The isolates were differentiated and typed by flaA-RFLP analysis.Campylobacter spp.were detectecl in caecal swabs in all 5 turkey farms with prevalence (90% to 100%).Both C.jejuni and C.coli were detected with prevalence ranged from (14% to 67% )and (33% to 86% ),respectively.Campylobacter was detected in drinkers and in dark beetles.No Campylobacter was isolated from main water tanks.flaA-RFLP assay showed that turkey farms can harbour more than one genotype.In a single turkey two different types could be detected.Observations of this study revealed that organic turkey flocks are often contaminated already at an early age with Campylobacter,drinking water and also dark beetle can play a role in the entry of Campylobacter into turkey flocks,a high degree of similarity between C.jejuni genotypes from both farm sites,higher genetic differentiation between Campylobacter populations from turkeys.A more thorough understanding of the transmission pathways is necessary in order to fight the spread of Campylobacter in organic turkey flocks by biosecurity control measures.
