Have you ever seen people with food allergies eat heartily at a company lunch? Without making their rounds asking, “Was this fried in peanut oil? Did this have contact with peanuts?”
Food is so bound up with work that eating out can be a stressful occasion for those with severe food allergies. For those people, certain foods can cause dangerous anaphylaxis, whose symptoms include difficulty breathing, sudden low blood pressure, hives, swelling, and loss of consciousness. Even trace amounts of an allergen can be dangerous. Peanut dust from a cutting board on which a juicy rib-eye steak was sliced could send someone to the ER.
