Ok, we have a guest coming tomorrow evening who I am told has strong nut allergies, and also is allergic to chickpeas. I have the meal sorted, but I'm concerned about the ambient allergens. I do a great deal of baking with almond flour. Right now said flour is in sealed bags in a cupboard, and I've wiped down and vacuumed the kitchen a few times since the bags have been out or opened. There is also an open bowl of in-shell nuts that's been in the livingroom and one of pistachios on the pantry shelf.
The guest should realistically only be in the hallway, front loo, livingroom, and kitchen while here. I've wiped down all the surfaces with detol wipes, but we have a lot of knick-knacks, jars, books, etc., that can only be dusted. We are using disposable plates and cutlery (were planning to do that anyway as I don't have enough china unpacked and it's an informal gathering). I've already sanitized the cookware, and I'm going to be dusting and vacuuming (with a hepa filter) in all the rooms again later today. I have removed any removable textiles (throws, pillows, etc.) and have vacuumed the upholstered furniture and rugs.
We have warned the guest that there are nut products in the house. For those people who deal with serious allergies, is there ~anything~ else that I can be doing to minimize any possible problems our guest might have? We want them to be able to have a nice time with the group.
