Despite your best efforts, there is always a possibility that someone with food allergens and intolerance may have an accidental exposure or reaction to your food. In such a case, you should act quickly and calmly. Identify the symptoms and the source of the reaction; common symptoms of food allergy include hives, swelling, itching, wheezing, coughing, vomiting, or fainting; common symptoms of food intolerance include bloating, gas, cramps, nausea, or diarrhea. If the person has severe or life-threatening symptoms like difficulty breathing, low blood pressure, or loss of consciousness, call 911 or seek medical attention immediately. If they have an EpiPen, help them use it as instructed by their doctor. Monitor the person's condition and provide comfort and reassurance until help arrives; do not give them anything to eat or drink unless they have a medical condition that requires it. Do not induce vomiting or give them antihistamines unless advised by a doctor. Afterward, report the incident and document the details; notify your manager or supervisor and fill out an incident report form with the date, time, location, person's name and contact information, food involved, symptoms, treatment and outcome. Keep a copy of the report for your records and follow up with the person later.
