In a chapter he wrote about the "intellectual and emotional world of the cockroach", entomologist Howard Ensign Evans included the story of a rather unusual dinner experience of his1.
I once had a cockroach served to me in an order of beefsteak and onions in Texas. (I believe it was an American roach, but accurate identification of fried specimens is difficult.) I was ravenously hungry after a day in the desert, so I cleaned my plate except for the cockroach, which I spread out neatly in the center of the empty plate, arranging his antennae and legs as best I could. The expression on the waiter's face when he picked up my plate was ample compensation for the health risk I took. Cockroaches are basically clean animals, but they do track about a good deal of human filth; domestic roaches have in fact been found to carry bacteria responsible for a variety of intestinal disorders, as well as polio virus and even hookworm. I survived my Texas meal well, although my sorting out of fried onions from fried roach parts was sometimes arbitrary.
As much as I like insects, I don't think I could eat a meal containing a cockroach. But I suppose I wouldn’t mind a snail crawling on my salad. Do we tend to be less prejudiced against what we are more familiar with?
