Sometimes foods have to be withdrawn or recalled if there is a risk to consumers. This could be because the allergy labelling is missing or incorrect or if there is any other food allergy risk, such as cross contamination. Allergy UK are informed by the Food Standards Agency and provide a free alert service where they alert the public via their website, social media and by sending allergy alert emails to those who have requested them. Patients can sign up to receive alerts for particular allergens.
