Leading restaurant and coffee shop chains are giving out incorrect allergy advice, BBC Watchdog Live has found.
Posing as customers with food allergies, journalists secretly filmed staff at Frankie & Benny’s, Pizza Hut, Nandos, Pizza Express, Starbucks and Costa.
The journalists asked staff whether dishes contained any of the 14 major allergens.
Five out of the 30 outlets visited gave the reporters incorrect information.
The unclear and incorrect advice could have caused anyone with a genuine allergy to have a potentially life-threatening reaction.
