The population of wild animals is increasing, and control strategies based on selective hunting are among the major options adopted. The game meat obtained is therefore available for controlled and certified valuable chains. The understanding of carcass contamination and the factors affecting it is therefore crucial to ensure meat safety and prolonged shelf-life. The carcass hygiene of 64 hunted wild male roe deer ( L.) was evaluated in relation to factors potentially affecting it. Aerobic colony and counts, as well as spp. and detection, were performed. The interaction of the microbial determination with age and weight of the animals, the climate conditions, the shooting procedure, the time between the killing and the evisceration as well as the time of storage of the carcasses in refrigerated conditions before skinning, were evaluated. Neither spp. nor were detected on the carcasses and the average loads detected were 3.39 ± 1.06 UFC/cm and 2.27± 1.11 UFC/cm for the aerobic colony count and count, respectively. The loads detected are similar to those reported by UE legislation for slaughtered species. The time of storage before skinning, the environmental temperature during hunting and the time between shooting and evisceration, associated with animal weight, affect the carcass hygiene and must be taken into careful consideration by hunters as food business operators.
野生动物数量在增加，基于选择性狩猎的控制策略是主要采用的方法之一。因此，猎获的野味可用于受管控且有认证的价值链。所以，了解胴体污染情况及其影响因素对于确保肉类安全和延长保质期至关重要。对64只被猎杀的野生雄性狍（狍属）的胴体卫生状况与可能影响其的因素进行了评估。进行了需氧菌落计数以及肠杆菌科细菌和假单胞菌属的检测。评估了微生物测定结果与动物年龄和体重、气候条件、射击过程、宰杀与开膛之间的时间以及在冷藏条件下剥皮前胴体的储存时间之间的相互作用。在胴体上未检测到假单胞菌属和肠杆菌科细菌，需氧菌落计数和的平均检测负荷分别为3.39±1.06 UFC/cm和2.27±1.11 UFC/cm。检测到的负荷与欧盟法规对屠宰物种所报告的负荷相似。剥皮前的储存时间、狩猎期间的环境温度以及射击与开膛之间的时间，与动物体重相关，会影响胴体卫生，作为食品经营者的猎人必须仔细考虑这些因素。
