Once you have been diagnosed with a shellfish allergy, you will need to avoid the types of shellfish you’re allergic to and foods that contain them.
Read the ingredient lists on food packets carefully every time you shop. Shellfish are included in the list of top 14 major food allergens in the UK. This means they must be highlighted on ingredients labels, in bold for example.
Read the ingredient list every time you buy a product as manufacturers change their recipes often.
When eating out
Restaurants, cafes, hotels, takeaways and other catering businesses are required by law to provide information on major allergens, including shellfish. Ask staff directly if the food you’d like to buy contains shellfish and let them know that even small quantities can cause a reaction. Don’t be afraid to ask staff to check with the chef.
Check if there is any risk of cross-contamination. For example, fried food such as chips could be cooked in oil which has been used to fry scampi, and stir fries can contain traces of prawns.
