LOL Womble!
I think that the violent-sick reaction to food poisoning is enough to make most people think twice about certain foodstuffs.
-Prawn mayonnaise sandwiches do that for me.
-But if I am the one to prepare the prawns then I'm happy. Similarly with mussels. Eating raw oysters is a bit like playing Russian roulette. They are massively over-rated too.
I will also go out of my way to avoid eating in a Macdonalds or a Little Chef.
But foods that frighten me? Sorry, I just don't get the concept. It's like a child asking me what's my favourite number or favourite colour. I see numbers and colours. I wouldn't choose a yellow car, but then again I'd be suspicious of a blue daffodil.
