3 Introduction Objective: Control/eradication of bovine tuberculosis 2010: Reinforcement of control measures Critical points identified: - extensive production systems with large herds (central and southern regions) - increased number of game deers and wild boars (last years) - frequent contacts with wildlife - epidemiological investigation - training

28 Measures implemented in 2011 Reinforcing the involvement and compromise of hunters and of their associations Reinforcement of surveillance regarding tuberculosis in deers and wild boars Reduction of deers and wild boars population (overpopulation), in order to achieve the biological balance of population More involvement of the farmers in the eradication Reinforcement of biosecurity measures on the herds (example: artificial barriers to prevent wildlife movements) Persisting with practical training tuberculin skin test application Maintain official controls in the field Maintain level of motivation and keeping farmers well informed
