Restaurant cross-contact checklist for food allergies
Cross-contact happens when an allergen gets into a dish that doesn't contain it as an ingredient. For guests with severe allergies it matters as much as the recipe. Walk the kitchen with this checklist and write down what you find.

Fryers and oil
List every item that goes into each fryer. Breaded shrimp, battered fish, and fries in the same oil means the fries carry shellfish, fish, wheat, and egg exposure. Note which oil each fryer uses.
Grills, flat-tops, and pans
Butter basted on the flat-top and cheese melted on the grill travel to the next item. Decide whether you can clean a section, use a fresh pan, or cannot avoid shared surfaces during service.
Prep stations, boards, and utensils
Check shared cutting boards, knives, tongs, ladles, and squeeze bottles. Nut and sesame garnishes near the pass are a common source of cross-contact.
Hands and gloves
Washing hands with soap and water removes allergen residue better than hand sanitizer alone. Change gloves before handling an allergy order.
Communication on the line
Flag allergy orders on the ticket, name one person who owns the dish from prep to pass, and have the runner confirm the allergy with the guest at the table.
Tell guests what you cannot avoid
When a shared fryer or station cannot be separated, say so in writing and at the table. A clear no is safer than a hopeful maybe.
Frequently asked questions
What is the difference between cross-contact and cross-contamination?
Cross-contact is the allergy term: an allergen protein gets into a food that does not contain it. Cooking does not remove it. Cross-contamination usually refers to bacteria or other pathogens, which cooking can kill.
Does a shared fryer matter if the oil is hot?
Yes. Frying does not remove allergen proteins, so items fried in shared oil can carry allergens from everything else cooked in it.
