To the Editor: The digenean trematode Alaria alata is considered an emerging zoonotic parasite in Europe because of increased findings in wild boars during Trichinella inspection. 0000050845 00000 n Recent incidental background findings of Alaria alata mesocercariae in meat of wild boars during official Trichinella inspection initiated a reassessment of the potential human health risk as posed by this parasite. Alaria is a genus of flatworms, or trematodes, in the family Diplostomidae. the genus Alaria but as they differed in a number of ways from the described forms, a new species, Alaria canis has been proposed for them. T. canis was more abundant in foxes while A. alata was more abundant in raccoon dogs. Clinical signs may be seen earlier due to immature stages and fluke migration.
