At about midday my mind drifts from the numerous emails and office politics and starts to consider my lunch options. Do I fancy a hot meal, a quick sandwich, healthy salad or maybe something a little more exotic? Sushi perhaps? Well not after speaking to Eileen Harris who works on parasitic worms! She’s doing a Nature Live event on the 31st August and I just met her to find out more about what her work involves. It’s fascinating, but you do need a strong, and preferably empty, stomach.
Parasitic worms live in everything from the largest whale to the smallest insects. Eileen will be bringing out a whole host (no pun intended!) of parasites to the event including her personal favourite, Eric; the 7m long tapeworm…definitely not one to be missed!
Back to sushi and let me introduce you to Anisakis simplex. This marine roundworm can be found in fish, eel and octopus and when you eat raw, unprepared seafood you could be also be swallowing live larval forms of this parasite. Needless to say once inside your system you’re going to know about it but the good news is that they usually die after a few weeks.
If, like myself, you’re a big sushi fan then rest assured that high-street sushi is safe as chefs are trained to identify these little parasites but they’re definitely something to look out for if you’re making it at home. Luckily Anisakis simplex is visible to the naked eye so happy hunting!
