This is the first report of the finding of in beaver meat () in Poland and Europe. In Poland, the beaver is a strictly protected animal species, except the few regions where high population density leads to economic losses. In these areas, the reduction culling of the animals was introduced. This uncommon hunting game animal is consumed and treated as a delicacy by hunters. However, currently, there is a lack of knowledge on possible risk factors for humans associated with the consumption of beaver meat. This paper presents the result of the study on the occurrence of nematodes of the genus in beavers.
In total, 69 beavers were examined for the presence of spp. The 50g samples were taken from each animal and digested separately, according to a procedure based on the EU reference method. The larva DNA was examined by PCR and sequencing.
One of the 69 examined beavers was infected. Only one larva was detected by the digestion method. The result of PCR confirms the presence of in beaver meat.
This case further confirms the ability of these typical herbivores to be infected with spp. This is the second confirmed case of spp. infection in beavers in Europe and the first of .
这是在波兰及欧洲首次在河狸肉中发现（某种线虫）的报告。在波兰，河狸是严格受保护的动物物种，但在少数因种群密度过高导致经济损失的地区除外。在这些地区，实施了对河狸的减量捕杀。这种不常见的狩猎用野生动物被猎人食用并视为美味佳肴。然而，目前对于人类食用河狸肉可能存在的风险因素缺乏了解。本文展示了关于河狸体内 属线虫出现情况的研究结果。
总共检查了69只河狸是否存在 属线虫。从每只动物身上采集50克样本，并根据基于欧盟参考方法的程序分别进行消化处理。通过聚合酶链反应（PCR）和测序检测幼虫DNA。
69只接受检查的河狸中有一只被感染。通过消化方法仅检测到一条 幼虫。PCR结果证实河狸肉中存在 属线虫。
该案例进一步证实了这些典型食草动物感染 属线虫的可能性。这是欧洲第二例河狸感染 属线虫的确诊病例，也是首例（具体线虫种类）感染病例。
