The peanut detectives

Pick up a random product from a supermarket shelf and there is a reasonable chance it will display the warning "May contain nuts".

Some consumer groups say the label is over-used and unnecessary, undermining more valid warnings and designed to cover the backs of the manufacturers.

A serious subject it might be, but do we need the warnings on packs of peanuts (and yes, I have seen them)? That's what natural selection is for, if you're too dumb to know that a pack of peanuts contains peanuts you probably deserve to suffer.
