Since 1 October 2021, new UK legislation has required all food outlets to provide full ingredient lists, with allergenic ingredients emphasised (for example in bold, italics or a different colour), on pre-packed for direct sale (PPDS) food.

Prepared, pre-packed and sold to consumers on the same premises, PPDS can include food that people select for themselves (from a display unit) as well as products sold at mobile or temporary outlets.

The UK Food Information Amendment, also known as Natasha’s Law, was brought about thanks to the actions of a lobbying group led by the parents of Natasha Ednan-Laperouse, a teenager who died after suffering an allergic reaction to an undeclared ingredient (sesame) in a Pret A Manger baguette.

Pret did not label “artisan” baguettes as containing sesame seeds despite six allergic reaction cases in the year before Natasha died, the inquest into her death in 2016 was told.

Mr Ednan-Laperouse said Natasha's Law would be vital in helping to protect the two to three million people in the UK living with food allergies from life-threatening allergic reactions.

The 14 allergenic ingredients covered by the legislation include wheat, eggs, fish, celery, nuts, mustard, milk and lupins.

Food Standards Agency (FSA) chief executive Emily Miles said: "If these changes drive down the number of hospital admissions caused by food allergies, which have seen a threefold increase over the last 20 years, and prevent further tragic deaths such as Natasha's, that can only be a positive thing."

Except where circumstances require immediate action, she went on, local authorities responsible for enforcing the law are being advised to take a proportionate and risk-based approach to breaches of the law.

The FSA is advising that minor errors are dealt with through extra guidance and support with the changes, particularly during the early months.

Products that will now need to be labelled include pre-wrapped sandwiches, fast food that is already in packaging before a customer places their order, and supermarket items such as cheeses and meat from the deli counter that are already wrapped and ready to be served.
