Not many do -- even those with shellfish allergies. I have an extreme allergy to shellfish. I LOVE sushi. Once pigged out on the stuff and had an anaphylactic reaction. No one could figure out why. Once I got out of the hospital, of course I had to go have more sushi. This time, the chef was very careful to make sure no shellfish touched my food, the knife, the cutting area, etc. Another trip to the hospital. Third time, took one bite of sushi and was rushed to hospital. The ER doc was the one who told me to avoid all horseradishes, especially wasabi. Checked with my allergist, he did some research -- yup, same proteins/histimines. So, it truly can be deadly for those with extreme allergies. Now, I just make sure there's no wasabi anywhere near my sushi and all is good with the world.
