Subject: RE: Duty, and Breaking Eggs

In answer to an earlier question, allergic reaction to eggs only rarely

results in anaphylaxis.


Here's another question. I'm allergic to tree nuts - if I eat them I get

an anaphylactic reaction. Consequently, I *always* take my adrenaline

auto-injector wherever I go. This is regardless of whether someone has

assured me that there's no nuts in food, because as this case shows, it's

always possible for mistakes to occur.


If this poor man knew he suffered an anaphylactic reaction to eggs, should

he have carried an adrenaline auto-injector with him, even if he thought

that there would not be eggs in the food? In that case, is there an issue

of contributory negligence? It would depend, I suppose, whether the

reasonable person who suffers from anaphylaxis is like me and takes her

adrenaline with her everywhere she goes.


Another question: how effective is the frequent disclaimer on food "may

contain traces of nuts"? I have never come across a more irritating

disclaimer. I'm allergic to tree nuts but not peanuts. I've talked with

other people who are allergic to nuts, and we've agreed that we generally

"risk it" when a product says "may contain traces of nuts" otherwise our

diet would become very limited indeed - just about everything has the

disclaimer, and it seems to mean "it's not our fault if, on a

million-to-one-chance, a peanut accidentally falls in the vanilla

ice-cream mix and gives you an allergic reaction". I've never had a

problem yet...although as I say, I carry my injector with me all the

time...
