Background: The huge disaster like as the Great East Japan Earthquake destroyed essential utilities and a lot of people were forced to live in shelters after evacuation. They have to stay at the temporary shelters for a while and have to take ration foods for regugees until they leave there. However, the refugees with food allergy cannot eat rations because no allergen-free foods are supplied. According to the reports, the caregivers of children with food allergies were confronted with difficulties to get allergen-free foods during the evacuation life after the Great East Japan Earthquake and about 5% food allergic children developed the allergic symptoms by the accidental ingestions of foods including the allergens. The ration foods without the allergens were developed after the Great East Japan Earthquake in 2011; however, they are insufficient to cope with the entire food allergens.
