LONDON (AP) — British restaurant chain Pret a Manger says a second customer has died after eating a sandwich containing an allergen that was not noted on the label. 
 
 The coffee-and-sandwich business has promised to improve its labeling following criticism at an inquest into the death of 15-year-old Natasha Ednan-Laperouse, who died in 2016 after eating a Pret baguette that contained traces of sesame. 
 
 The company said an investigation was underway into a second case, in which a customer died in December after eating a supposedly dairy-free product that contained dairy protein. Pret a Manger blamed a supplier of its dairy-free yoghurt. 
 
 The parents of Ednan-Laperouse, who are campaigning for stronger allergen warnings, said Sunday they were "incredibly saddened to learn of someone else losing their life from allergens in their food." ||||| Pret a Manger has been hit by further controversy over the weekend, as it emerged that a second customer had died after eating one of its sandwiches in 2017. 
 
 The sandwich chain found itself in a escalating row with a former supplier, after it blamed the second death on an ingredient supplied by the vegan brand CoYo, a claim the yoghurt company said was unfounded. 
 
 It emerged on Saturday that a Pret customer had died in 2017 after eating a “super-veg rainbow flatbread” that was supposed to be dairy-free. 
 
 Pret said it had been mis-sold yoghurt that forms one of the ingredients of the flatbread and which was guaranteed dairy-free but was found to contain dairy protein. 
 
 The company agreed to full labelling of ingredients on all its freshly made products last week following the case of 15-year-old Natasha Ednan-Laperouse, who was allergic to sesame and died on a flight after eating one of its baguettes bought at Heathrow airport. 
 
 Following the news of another death, Natasha’s parents, Nadim and Tanya Ednan-Laperouse, said: “We were incredibly saddened to learn of someone else losing their life from allergens in their food. Our hearts go out to the bereaved family.” 
 
 The pair have been campaigning for allergy awareness and a change in food-labelling laws.

 The second customer, who has not been named, collapsed and died on 27 December after buying the sandwich in a shop in Stall Street, Bath. 
 
 Bath’s council alerted Pret to the incident and the chain said it withdrew all affected products. The firm said it had ended its contract with CoYo and was taking legal action. 
 
 “Subsequent testing by Pret and two independent authorities found that the CoYo dairy-free yoghurt contained traces of dairy protein,” a Pret spokesman said. “This is believed to have resulted in the tragic death of a customer from an allergic reaction in December 2017. 
 
 “Our deepest sympathies are with the family and friends of our customer in this terrible case and we will seek to assist them in any way we can.” 
 
 CoYo, a coconut milk brand that the TV cook Nigella Lawson has endorsed, said on Sunday that Pret’s claims that it was to blame were unfounded. It accused the sandwich chain of hampering its own investigation into the death by failing to provide vital information. 
 
 “Pret’s inability to provide us with a batch code, despite several requests, has severely limited our ability to investigate this further,” it said 
 
 CoYo recalled its yoghurts in February 2018 after dairy traces were found. The Food Standards Agency investigated together with Bexley council in London, where CoYo is based, before it issued an allergy alert. 
 
 CoYo denied on Sunday that the product recall was related to the death. “The dairy-free product we provided to Pret in December 2017, at the time of this tragedy, is not linked to the product we recalled in February 2018,” a spokeswoman said. 
 
 The company would continue to help to find the true cause of the death, she said. “We urge all parties to work together, and not to speculate on the cause of this tragic death which is unknown as far as we are aware and is still being investigated by the coroner’s court.” 
 
 Following the February recall, Coyo said it had been devastated to discover dairy in its yoghurts, “especially as being dairy-free sits at the heart of everything we do”. 
 
 It said it had carried out a “thorough review” of its ingredients and identified that the contaminated material was provided by an external third-party supplier, whose relationship had now been terminated. ||||| Video report by ITV News Correspondent Emma Murphy 
 
 Food labelling laws were "playing Russian Roulette" with the life of a teenager who died after eating a Pret a Manger sandwich, her father says. Natasha Ednan-Laperouse, who had a severe sesame allergy, died after eating an artichoke, olive and tapenade baguette that did not label all the ingredients. The coroner called Pret a Manger's allergy labelling "inadequate" on the final day of the inquest into the death of the 15 year old who fell ill on a BA flight from London to Nice. He found the teenager was "reassured" by the lack of specific allergen information on the packaging of the sandwich, and said he would be writing a report to the government on his concerns about allergen labelling. 
 
 Our beloved daughter died in a tragedy that should never have happened. If Pret a Manger was following the law, then the law was playing Russian Roulette with our daughter's life. It's clear that the food labelling laws as they stand today are not fit for purpose and it's now time to change the law. Natasha's inquest should serve as a water shed moment to make meaningful change and to save lives. – Natasha's father Nadim Ednan-Laperouse MBE

 Saying the company is "deeply sorry" for Natasha's death, the CEO of Pret a Manger Clive Schlee told reporters: "We want meaningful change to come from this tragedy. We will ensure that it does." The teenager, from Fulham, was travelling with her father and her best friend for a holiday in July last year, when she went into anaphylaxis. A video released by her family shows her smiling at the camera on the plane prior to takeoff, shortly before she became ill. 
 
 The coroner Dr Sean Cummings detailed how Ms Ednan-Laperouse began to suffer an allergic reaction on the flight. She said to her father, “Daddy please help me I can’t breathe,” and he injected her twice in the same leg with her EpiPen. The court was told the second may not have been effective as it was administered to the same leg. “Mr Laperouse I cannot imagine how that experience was on that plane,” Dr Cummings said to Natasha's father Nadim Ednan-Laperouse MBE. “Terrible,” he replied.

 Despite the injections being administerd, the 15-year-old was pronounced dead hours later at a hospital in Nice. The coroner added he will be writing to Pret about collecting information on allergic reactions.

 Dr Cummings said: "Natasha Ednan-Laperouse died of anaphylaxis in Nice on July 17 2016 after eating a baguette, purchased from Pret A Manger at London Heathrow's Terminal 5. "The baguette was manufactured to Pret specifications and contained sesame to which she was allergic. "There was no specific allergen information on the baguette packaging or on the (food display cabinet) and Natasha was reassured by that." Earlier in the five-day hearing the inquest was told the packaging failed to mention that sesame seeds were "hidden" in the dough. It also emerged that a "specific warning" about the dangers of not signposting the allergen had been given to the food chain the previous year. The court heard how the chain had made use of reduced allergen labelling requirements for shop-made food - which is intended to benefit smaller, independent stores.

 Dr Cummings said on Wednesday: "It seems a little strange a local sandwich shop could benefit from that regulation but an organisation that sells 218 million items (a year) should also benefit from that regulation.” The coroner continued: "A cynic might think it was almost a device to get around regulations relating to identifying food allergens." Under EU regulations, food companies are required to warn customers about allergy risks either on signs and packaging or orally, usually meaning they are told to inquire themselves. Pret chose to deliver allergy information orally and was supposed to have stickers within fridges telling customers to ask staff members for details, the inquest heard. British Airways cabin crew were also questioned over their response after the inquest heard that the on-board defibrillator was not used in-flight.
