You need to get educated before you kill your nephew. They have to make sure the bread comes from a place where they don’t make anything with peanuts (cookies, cakes, etc). The ingredients may be peanut free but if the machine was used to make something else before, it could get contaminated. I think it is the same way for gluten-free foods. Peanut allergies are really badUmmmm they buy bread all the time.
Unless you go to the bakery section, odds are you aren’t going to find bread with nuts in it.
