Wow! My son is allergic to baked beans and this is the first time I've heard of someone with this allergy!! The strange thing is I found a photo of him recently at probably age 18 months tucking into a plate of beans on toast
Shortly after that he became allergic, he vomits and comes up in hives, his eyes swell too. Its not nice
He's almost 11 now and still allergic, he cant eat food that has been touched by baked beans or even the sauce they come in. For a while I thought it was the sauce but I rang Heinz as he eats their spaghetti hoops without a problem and they told me the recipe for the sauce for the hoops and the baked beans is exactly the same. We have also tried him with red kidney beans and his reaction was the same.
