In the UK, food businesses must tell you if they use any of the 14 key allergens as ingredients in the food and drink they provide.
Food businesses include restaurants, cafés and takeaways, and businesses that produce, manufacture or pre-pack food.
The 14 allergens that they need to declare are:
- cereals containing gluten – including wheat, rye, barley and oats
- crustaceans – such as prawns, crabs and lobsters
- molluscs – such as mussels and oysters
- tree nuts – including almonds, hazelnuts, walnuts, brazil nuts, cashews, pecans, pistachios and macadamia nuts
- sesame seeds
- sulphur dioxide and sulphites (if they are at a concentration of more than ten parts per million)
