There seems to be a big thing now with TV advertising promoting the fact that some manufacturers are labelling their products, always junk foods though, as "peanut free". Peanuts are not the only food allergen in the world, though to see the marketing you'd think it was.

I realise that peanut free foods are useful, but there are loads of them about anyway, like fruit, vegetables etc. And making sugary snacks peanut free for school lunch bags is not only a perceived "safety" issue. It's also a gimmick.
