The best prophylaxis is to avoid the consumption of raw, smoked, or pickled fish. Second Intermediate Host Second intermediate hosts include freshwater, anadromous, or marine fish. Identification of Diphyllobothrium plerocercoids in marine fish is more problematic 5,and molecular-based diagnostics will be necessary to confirm previous records, including those of D.

The importance of reliable identification of human-infecting species with molecular tools sequences of mitochondrial genes as well as the necessity of epidemiological studies aimed at determining the sources of infections are pointed out.
