Researchers identify Japanese tapeworm parasite in Alaskan-caught salmon

In 2012, a Japanese man with a fondness for chilled salmon came down with what physicians described as a “watery” bout of gastrointestinal distress. This was uncomfortable enough, but his illness took a turn for the shocking. The 40-year-old discovered that a meter-long “tape-shaped object” had “emerged from his anus,” according to a 2012 article in BMJ Case Reports. At that point the man decided to check himself into a hospital.
