Important Safety Information You Must Know
Cross Contact in the Kitchen
McDonald's prepares food in kitchens where all 14 major allergens are present. Even if you remove an ingredient from your order, the restaurant cannot guarantee your meal will be completely allergen free.
Shared Equipment Risks
Toasters: All buns, rolls, and tortilla wraps go through the same toaster as sesame topped buns. If you have a sesame allergy, traces may be present even on plain buns.
Cheese Handling: Due to how cheese is stored and handled, milk traces can appear in items even when you request no cheese.
Frying Oil: Fries, Hash Browns, and Veggie Dippers all cook in the same oil. This shared cooking method means cross contact between items is possible.
Delivery Orders
When ordering through delivery services, your McDonald's meal may travel alongside other orders containing different allergens. The courier might carry multiple McDonald's orders or meals from other restaurants, increasing the chance of cross contact during transport.
Always Check Packaging
Ingredient lists and allergen warnings appear on all packaging. Even if you've ordered the same item before, recipes can change, so checking each time protects you best.
How to Stay Safe When Ordering
Read the Latest Information: McDonald's updates their allergen guide regularly. Always check www.mcdonalds.co.uk/nutrition before ordering to see the most current ingredient lists.
Ask Questions: If you're unsure about anything, speak with the restaurant staff or contact McDonald's Customer Services before placing your order.
Know Your Limits: If you have severe allergies, understand that cross contact cannot be eliminated in a shared kitchen environment. Make your choice based on your personal risk tolerance.
Keep Emergency Medication: Always carry your prescribed allergy medication when eating out, regardless of how careful you are with menu selection.
