 Food allergens are a problem all over the world and allergens exist in every country but I guess the priority or the main allergens are concerned are not always the same in every country. And so in some countries milk, eggs, wheat might be the high priority ones but if you then go to other countries. For instance around Switzerland, Germany, celery is a specific problem. So the European Union mandates celery to be a listed allergen which in the rest of the world is not a problem of concerns. So often you'll find various regions of the world have other allergens on their lists that do not cause a problem in the rest of the world. We identified lupin as an allergen of regional concern and it tends to be a problem in the countries that grow and eat lupins. So Eastern Europe and Australia strangely enough. Prawn is a very common allergy within Western countries but if you go to Southeast Asia they do have a prawn allergy but it appears to have a completely different basis and isn't apparently as severe. It's to do with exposure and it's the protein in the allergen that some people for one reason or other become sensitized to. As I say in some countries exposure might lead to an allergy. In other countries people can consume the same food quite safely and that has I think has a lot to do with where you live. So the climate, the conditions, the environment you live in, the temperature could be whatever else is in the environment, what are the things you might be exposed to and things like cross contact allergy is interesting. It's something we have to live with and it's always going to be with us. I think it's a case of being ahead of the game and on top of it managing.
