Epidemiological Investigation of Bovine Tuberculosis Infection Dynamics in Turkey

Abstract

A national epidemiological research project was carried out to define the dynamics affecting the epidemiology of bovine tuberculosis (bTB) infection in Turkey and to identify the risk factors. Official veterinarian (OV) and breeder original questionnaires were produced separately as part of this study to collect thorough data regarding the disease from the field. The number of questionnaires that needed to be filled out was decided by 95% confidence interval (CI) and 5% margin of error. The findings of 371 OV and 317 breeder questionnaires completed online across the country were analyzed. In addition, 28 outbreaks determined by random method were visited. To observe regional differences and field conditions, the opinions of OVs who monitored the disease and breeders were compiled. It was observed that the data obtained from both questionnaires was largely compatible. The main factors in the epidemiology of bTB infection were found to be effective fight, development of state policy, providing adequate financing, animal purchase, ear tagging and records, animal traders, animal markets, animal movements, conditional slaughtering, slaughterhouses, postmortem inspection, premise conditions, socio-economic impact, evaluation of raw milk, disease-free premises, compensation payments, and quarantine processes.
