Parasites - Zoonotic Parasites & Food Safety

Many parasites of fish may also infect humans and therefore represent a significant health risk, particularly where the consumption of raw or lightly processed / pickled fish is common. The parasitology research group has investigated a number of potential human pathogens including the tapeworm Diphyllobothrium spp., and a wide range of digenean parasites, particularly from Vietnam and Korea, including Clonorchis, Opisthorchis and Heterophyes. Anisakid nematode worms, which can pose a risk to human health are a common parasite of many commercially exploited marine food-fish including cod, haddock, herring, mackerel and many others. Work in the Parasitology Research Group, in collaboration with the Food Standards Agency Scotland, has examined, the occurrence of these worms in monkfish, cod, herring and mackerel captured in Scottish waters, as well as investigating optimal techniques for their detection.
