What the food allergens are
Find out what food businesses are responsible for, how to tell if they’re allergy aware and what to do if someone has an allergic reaction.
Allergens and food businesses
It's the responsibility of all food businesses to provide accurate allergen information if anyone asks for it.
It is very important to be allergy aware as allergic reactions can sometimes be life threatening.
The 14 allergens recognised in law are:
- cereals containing gluten, like wheat, rye, barley, oats, spelt, kamut and their hybridised strains
- peanuts, also called groundnuts
- nuts, like almonds, hazelnuts, walnuts, Brazil nuts, cashews, pecans, pistachios, macadamias and Queensland nuts
- crustaceans, includes crabs, lobsters, shrimps and prawns
- molluscs, includes mussels, cockles, oysters, scallops, squid and octopus
- sesame seeds
- milk and milk products, including lactose
- soy beans
- sulphur dioxide and sulphites at levels above 10mg per kg or 10mg per litre expressed as SO2
The Food Information Regulations 2014 require a food business to provide information to customers about the allergen content of all its food.
It is a criminal offence not to provide this information.

What to do if someone has an allergic reaction
If you or someone you’re with feels ill or has a reaction to a meal, make sure you seek medical help immediately.

If you have a food allergy, when you eat food from restaurants, cafes, takeaways or buy food from places that make it themselves, always announce your allergies or intolerances before ordering. This is so that the business can tell you what is safe for you to order.
Be aware that even wrapped food does not always have allergen labelling. This is because the current law allows people to give verbal allergen information in some situations.
How to tell if a food business is allergy aware
It's good practice for a food business to display an allergen poster advising you to ask about allergens in food. They may also display allergen details on their menus.
If you feel that a business is not very helpful in supplying allergen information, report it to Citizens Advice Consumer helpline or phone 03454 040 506.
