First case of Trichinella spiralis infection in beavers (Castor fiber) in Poland and Europe.

Abstract

Background

This is the first report of the finding of Trichinella spiralis in beaver meat (Castor fiber) 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 Trichinella in beavers.

Methods

In total, 69 beavers were examined for the presence of Trichinella 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.

Results

One of the 69 examined beavers was infected. Only one Trichinella larva was detected by the digestion method. The result of PCR confirms the presence of T. spiralis in beaver meat.

Conclusions

This case further confirms the ability of these typical herbivores to be infected with Trichinella spp. This is the second confirmed case of Trichinella spp. infection in beavers in Europe and the first of T. spiralis.
