Background and Aim: Due to the particularities of the first steps of the game food chain, large game species are shot, bled, and handled in collection points (spot of evisceration and initial examination in the field). These steps of the game meat chain affect the microbiological quality of this type of meat, thus posing a risk to consumers. This study aimed to characterize the collection points in terms of central hygiene and biosecurity procedures/requirements. Materials and Methods: One survey with 16 questions was applied in 95 hunting areas throughout Portugal. It was a convenience sample obtained by direct visualization on-spot procedures. Four categories were characterized in the survey: Initial examination (performance assiduity and type of operator performing it), hygiene requirements on-spot (floor, ceiling, water, and electricity), biosecurity procedures such on initial examination (use of personal protective equipment as gloves, glasses, mask, and specific clothes), and by-products disposal (destination and packaging of by-products). Results: Sixty percentage (n = 57) eviscerated the carcasses and performed the initial examination on-spot. Moreover, most of the time (n = 71), the initial examination was carried out by veterinarians. However, the category that showed the best results was those related to the biosecurity procedures on initial examination, mainly with the use of the individual protective material (e.g., regular use of disposal clothes and specific clothes). Concerning the questions about the disposal of by-products, 66 game managers say that this was done correctly (69%), being the majority destination of the inspected carcasses was the burial (64%; n = 47). Conclusion: This survey demonstrates an immediate need in all this problematic of the standardization of hygiene and biosecurity requirements of the collection points, which requires uniform application of rules. There is a lot of resistance and limitations to the inclusion of these requirements in collection points, due to lack of structural and financial conditions. However, training all those involved in the hunting area (hunters, game managers, authorities, etc.) creating rules that promote hunting food security and setting limits on the microbiological criteria of game meat are hot points to consider in the future. Keywords: food safety, good practices, public health.

Knowing the specific characteristics and animal tuberculosis risk factors present and applying good practices are crucial points in combating tuberculosis (TB) in a Mediterranean multi-species scenario. The objective of this work is to statistically analyze the association between the existence of TB in areas with a marked game–livestock interface, with various complementary factors found in 30 extensive farms in southern Portugal, such as the number of animals of each large game species present in the territory and the frequency of their sightings. Collecting this information, an inferential statistical analysis was conducted to obtain information on the association type between TB occurrence in the farms and the presence of highlighted factors. The main statistical results show an association between the presence of large game species and TB occurrence in the analyzed areas. Thus, in a multi-species scenario, large game species are a crucial component in TB maintenance, namely when stricter contact occurs. This could be one of the reasons why TB continues to circulate and why the eradication process is so difficult; the risk of zoonotic transmission is evident. It is crucial to apply biosecurity tools to improve the alignment and structure of natural resource management strategies.
