Pret A Manger did not label “artisan” baguettes as containing sesame seeds despite six allergic reaction cases in the year before a girl died, an inquest has heard.
Natasha Ednan-Laperouse, 15, reacted to the seeds in the food outlet’s baguette which she bought at Heathrow Airport before flying to France in July 2016.
She collapsed on the flight, suffered a cardiac arrest and died within hours.
A Pret A Manger representative said allergen policy had since been changed.
There were nine cases of sesame-related allergy incidents in the year before Natasha died, including six that involved “artisan baguettes”, according to a complaint log for the company.
In one of these cases a woman nearly died after suffering an anaphylactic reaction from a baguette in October 2015, West London Coroner’s Court heard.
Jeremy Hyam QC said the customer’s family afterwards gave Pret A Manger a “specific warning”, but the chain still failed to label sandwiches with allergy information.
The firm’s head of Risk and Compliance, Jonathan Perkins, said Pret reviewed its warning notices in April 2016.
“When we get it wrong, we like to put it right,” Mr Perkins said.
