Tapeworm from Asian waters found in Southcentral Alaska salmon

Scientists have found evidence that a parasite from Asian salmon has been spreading to North American fish, according to a newly released study on samples taken from Southcentral Alaska. The study,(click here) appearing in February’s issue of the journal Emerging Infectious Diseases published by the U.S. Centers for Disease Control and Prevention, reports on the discovery in Alaska salmon of Japanese broad tapeworm. Its authors say the results could mean Japanese broad tapeworms infecting humans have been mistaken for fish tapeworm, a species known by the CDC to affect North American fish. Scientists have found Japanese broad tapeworm, which was first identified in 1986 and can affect humans who consume infected fish raw, in chum, masu, pink and sockeye salmon from Japan and eastern Russia. About 2,000 cases of humans infected by the tapeworm have been reported primarily in northeast Asia, although the study’s authors say infections are likely under-reported. Read the story here 11:24
