Another mystery Baked Bean reaction

[heliotrope]

Hello
Saw a thread a while back about unexplained reactions to baked beans and now we've had one too.
Zach is allergic to milk, egg and white fish.
Fed him Sainsbury baked beans on toast with pure sunflower spread, also mushrooms cooked in olive oil - everthing he is normally fine with - but got the red rash and hives all over chin, neck and around lips.
Checked bean and bread ingredients and there is nothing there to indicate this might happen.
Any ideas, anyone else had this and got to the bottom of what it could be?
Thanks

its quite possible your child is allergic to beans.

beans are related to peanuts, and 5% of peanut allergic people are allergic to beans.

my son was allergic to all beans, but passed a recent baked bean challenge in hospital age 12.
he has out grown chick pea as well.
he is allergic to kidney beans, as well as other foods.

I think this is worth adding to your avoidance foods list.

well we've always been fine with Sainsburys baked beans so I wouldn't worry too much about a new allergy to nuts or lentils. Could there have been skimmed milk powder in the toast as it's in lots of bread? Sounds like contamination of either the beans, the spread or the bread but you're unlikely ever to find out which it was.

ds1 has a mild reaction to some brands of ketchup, ends up with a rash round his lips. Could it be something in the sauce?

Thanks for your thoughts, I hadn't thought about the beans - that is a really good point although he tested clear for peanut and soya so I was hoping to avoid the whole legume thing.
I really hope it was contamination of something and therefore a one off, you're right that I'll never know. I will try him with a different brand of bean to be sure.

Could it be the tomato sauce? CHildren I used to look after would often get a couple of hives after eating beans in tomato sauce/pasta with tomato sauce. Only sometimes though and never severe. If it was itching them then we would give piriton. But usually children never noticed. They do have anaphylactic reactions to other things so were already very limited at what they COULD eat. Seems to have stopped now.

don't try C&B beans then - know a couple of nut allergic people who have reacted to them.
