“…By force of Notice No. 1/2011, Idanha-a-Nova county is included in the "Portuguese Epidemiologic Risk Areas for Bovine Tuberculosis in Large Game", due to the high TB prevalence in wild boars and red deer, as already reported in previous research [7,8,15].…”

Since April 2011, Portugal has implemented specific national legislation (Notice N.º1/2011), defining “Epidemiologic Risk Areas for Bovine Tuberculosis in Large Game” and mitigation measures in these areas, including Idanha-a-Nova county. A GIS project was created to record information that would allow us to analyse the spatial–temporal distribution, both for hunting bags and tuberculosis occurrence, in hunted wild boar and red deer in Idanha-a-Nova. Hunting bag and tuberculosis-like lesion data were recorded during post-mortem inspection across 11 hunting seasons, totalling 9844 animals. The difference in tuberculosis occurrence for these species was statistically significant in nearly all 11 seasons, with wild boars presenting approximately twice the occurrence of red deer. No significant difference was noted before and after the Notice N.º1/2011 implementation. These results, following GIS-based spatial analysis, enable us to state that both large game species displayed an irregular tuberculosis pattern for the 2006–2016 period, and we identified some specific areas of high risk for both species. Southern areas of the county may be considered the priority for intervention. This research demonstrates the potential of GIS tools to evaluate, in the field, the results and efficacy of legislation such as Notice N.º1/2011, and to ensure the correct implementation of cost-effective mitigation strategies for tuberculosis in large game species.
