I think we should all be questioning the mental sanity of anyone who thinks moving poison away from food, especially poison that may legitimately be mistaken for food, is in any way a bad thing.
Did you read that story on the news about supermarkets having been told to remove daffodils bulbs away from vegetables so customers don't get confused with normal onions that you can eat because daffodils bulbs are toxic and make you vomit if eaten? Well it happened to me ! I accidentally ate some daffodil bulbs. When I got home I was taken seriously ill and was rushed to hospital! But don't worry everyone, the doctor said I should be out by the spring.
Must admit, initial reaction is 'elf and safety gone mad' - it would be difficult to imagine any European mistaking daffodils for spring onions- but having said that- people from another culture may well make the mistake, especially as they are now sold in bunches with very tight buds- which will only open up when you get them home, and after a few days.
But surely, the smell when you cut them up would soon tell anyone something is not quite right- daffodil stems have no smell at all, whereas spring onions are pretty pungent. Still- better be safe than sorry perhaps.
People have been poisoned in the past mistaking leaves of lilly of the valley for wild garlic- but again, smell would be pretty indicative.
Reminds me of a British family on camping holidy in France. They send the eldest boy off to the supermarket to do some shopping, telling him "mind the budget, get the cheapest of everything". He knew that wine was vin and noticed the wine called vinaigre was cheaper than the other wines. Nobody noticed until dinner was served.
