Cross-Contamination Guide for Coeliacs

Even gluten-free ingredients can become unsafe through shared equipment, fryers, and kitchen practices.

At home

• Dedicated toaster, butter dish, and chopping boards.
• Store GF flours separately — flour dust aerosolises easily.
• Clean colanders and utensils used for wheat pasta.

Restaurants

• Shared fryers — chips may be contaminated by battered foods.
• Pizza ovens, sandwich presses, and grill surfaces.
• Ask about soy sauce, flour thickeners, and dedicated prep areas.

Supermarkets

• Bulk bins and bakery display cases.
• "May contain wheat" on otherwise safe-looking products.
