Are urban tapeworms on the rise?: Scientific American Blog

This story combines two of my interests: parasites and Japan!:

Once the bane of rural Japanese villagers, a paper in the June issue of Emerging Infectious Diseases reports on the spread of the the salmon tapeworm Diphyllobothrium nihonkaiense. The parasite, which can reach lengths of 39 feet (12 meters), has been steadily increasing its global distribution and prevalence – mostly among yuppies with a hankering for sashimi and ceviche.

One hospital in Japan reported 14 cases last year, up from 3 cases in 2000. And starting in 2006, the tapeworm has been popping up for the first time in North America and Europe. Meanwhile, farm-raised salmon from South America have been plagued by a closely related tapeworm that normally infects perch and other freshwater fish.

An easy solution: cook your fish.

Speaking of parasites, my daughter came out of the toilet at McDonalds last week and announced loudly "There was a worm in my poo!" When I expressed doubt, she told me its head was moving and it was really true. She was not particularly bothered by the discovery; she was pretty excited in fact.

I am not sure what to do about this. I think it more likely to be a case of mistaken identity. The most common kid's intestinal worm in Australia is the threadworm, but I believe they are not so obvious, and she has none of the classic signs.

We are awaiting another sighting, this time at home.

Readers will be informed if positive identification is made. (I bet you're glad you read this blog....)
