I used to like Food Festivals and the like before salmonella was confirmed at a food festival in Newcastle earlier this year (see here and here).
I hate to touch things from food festivals now - I'm really cautious about doing it, if so.
Not quite sure what it fits in with in the Business Studies curriculum (GCSE), but we went over it for a week or two in the last academic school year. I didn't come down with anything, but my Business Studies teacher said he did.
