The new law comes after teenager Natasha Ednan-Laperouse suffered a fatal reaction to a sandwich in 2016.
Pret allergy death
Steve Harris spoke to Stuart from Poole for reaction to the news that new legislation will require a full list of ingredients to be put on pre-packaged food. Natasha's Law hopes to prevent people suffering avoidable allergic reactions. Stuart suffered a near fatal incident - when given a drink with lemon grass in it without labeling and 'died for a few seconds' when he was a teenager.
The parents of a girl who died after eating a Pret sandwich have welcomed new proposals to list ingredients.
The Food Standards Agency has decided to recommend changes in the labelling of ready to eat food, to highlight the dangers of allergens.
At the moment food prepared on the same site as it is sold, doesn't have to have warning labels about allergens, because it is assumed anyone who needs to know will ask the staff who made it about the food's ingredients.
The flaw in that system was exposed by the death of 15 year old Natasha Ednan-Laperouse who collapsed after eating a baquette from Pret a Manger which contained sesame seeds, to which she was allergic.
Pret a Manger has already started rolling out full labelling on all its products in its stores.
