Following the tragic death of Natasha Ednan-Laperouse, the teenager who died after suffering an allergic reaction to a Pret a Manger baguette, the government confirmed in September 2019 that stronger laws would be implemented to protect those with allergies and give them greater confidence in the food they buy.
‘Natasha’s Law’ will come into force in October 2021, with businesses, including schools and colleges, having had a transition period to prepare for the new rules. The Food Standards Agency
will publish information for industry on October 1 to help ensure that businesses of all sizes can prepare and adapt to these changes.
