My DH is allergic to beans (kidney, black, etc). His reaction is anaphalxis (throat, tongue, lips, etc swell). Sometimes he'll have a little contact and he'll feel his throat swelling, but it doesn't progress. Even when he has a larger reaction, he always has time to take benadryl and that resolves the reaction.
Lately he's been noticing himself have small reactions at times when he doesn't think he's eaten anything to which he should be reacting. However, I've been using beans more for meals for the kids and me.
I'm wondering if DH's reactions are a cross-contamination issue?
If I cook beans in a pan, if I just wash it, is it then safe to use for food for DH? Or do I need to take more elaborate precautions? Should I have separate dished for him? If I wash it in the dishwasher on high heat/sanitizer mode would that be better?
I was going to make some waffles that incorporate white beans in the batter. Now I'm wondering if I put them on the waffle-maker if I will contaminate it.
Any thoughts?
