Abstract

This study investigates the microbiological conditions of large game animal carcasses following evisceration. Carcasses of animals (N=291) hunted in the Upper Susa Valley (Italian Alps) were analysed for pH, Aerobic Viable Count (AVC), Enterobacteriaceae, Yersinia spp., Listeria monocytogenes and Salmonella spp. After shooting, evisceration occurred within 60 min in 90.7% of animals and sampling within 90 min in 88.3% of animals. Mean pH values (5.97: ruminants; 5.77: wild boar) were similar to those of regularly slaughtered domestic species. AVC values were highest in animals shot in the abdomen. Within species, AVC and Enterobacteriaceae values did not differ across different shooting-evisceration/sampling times. However, these counts exceeded 5 and 2.5 log, respectively, in 18% of wild boar and 39% of ruminants; the highest values were detected in wild boar. No pathogens were detected in any species. These results reveal inadequate hygiene in game meat handling/harvesting, implicating the need for improved practices.

摘要

本研究调查了大型猎物动物屠宰后的微生物状况。对在意大利上萨伏依谷（意大利阿尔卑斯山）狩猎的 291 只动物的尸体进行了 pH 值、需氧活菌计数（AVC）、肠杆菌科、耶尔森氏菌属、李斯特菌单核细胞增生症和沙门氏菌属的分析。在 90.7%的动物中，在射击后 60 分钟内进行了屠宰，在 88.3%的动物中在 90 分钟内进行了采样。平均 pH 值（反刍动物为 5.97；野猪为 5.77）与常规屠宰的家养动物相似。在腹部中弹的动物中，AVC 值最高。在同一物种中，不同的射击-屠宰/采样时间之间的 AVC 和肠杆菌科值没有差异。然而，在 18%的野猪和 39%的反刍动物中，这些计数分别超过 5 和 2.5 个对数，最高值出现在野猪中。在任何物种中均未检测到病原体。这些结果表明在野味肉的处理/收获过程中卫生条件不达标，需要改进相关措施。
