Comparative intradermal tuberculine test in dairy cattle in the north of Ecuador and risk factors associated with bovine tuberculosis

The rising demand for milk and dairy products in Ecuador increases the risk of tubercular infection not only in the population, but also in cattle, given the development of more intensive production systems in order to meet the increasing demand. To guarantee food safety, therefore, dairy cattle should be made tuberculosis-free. To this end the infected cattle and farms must be identified, likewise the risk factors for the transmission of the disease, so that the necessary policy decisions can be developed. The study presented here meets this objective, because a scientifically-based methodology has been developed and validated.
Twenty dairy farms with a total of 2,022 cattle were sampled for carrying out the tuberculine test. The prevalence of tuberculosis could thus be linked to what were identified in the study as risk factors. These are lactation stage, herd size, animal purchase, contact with other species, and the respective interaction factors. Over the two years studied the prevalence averaged 7.3%, varying from 0.42% in small farms to 8.53% in large ones. In addition to herd size, age and contact with other species were found to be the leading risk factors, with interactions from the districts in which the farms were located.
By using this approach the prevalence of tuberculosis in other parts of Ecuador can be further studied in order to make policy decisions for the maximization of food safety as regards milk production.
