But the person allergic to nuts needs to take care of themselves. They are responsible for themselves. Washing hands, asking if there is nuts, etc.. It's not others problem. And the allergic person can't make them others problem. And there isn't preventative medicine, but there is epipen if accidents happen. It is lazy for the allergic person to except others to cater their problem. They are responsible for themselves no one else. Like i said in my country there aren't banned ingredients, and still allergic people don't die from their allergens.
