Mia Shay St Hilaire, a 12-year-old girl, died after drinking a milkshake mixed in an unwashed blender at a south London cafe. The inquest into her death wrapped up at Inner South London Coroner’s Court on Thursday, Oct. 8, 2026, where the coroner pointed to failures and missed opportunities in how the child’s allergy had been handled.

Mia lived in Sydenham, southeast London, and had a hazelnut allergy. She was out with her aunt and sister in August 2023 when she ordered a Twix milkshake at the Pop Inn Cafe on Southwark Park Road in Bermondsey.

What the Coroner Found

Assistant coroner Briony Ballard heard the evidence and published a narrative conclusion.

Ballard said Mia drank part of a Twix milkshake that had been “cross-contaminated with hazelnut residue from a Kinder Bueno milkshake previously prepared in the same unwashed blender.”

The coroner found that anaphylaxis came on rapidly and that Mia collapsed at her aunt’s home. She received extensive emergency treatment and then intensive care at the Evelina London Children’s Hospital, where she died.

Closed-circuit television footage showed that Baris Yucel, the Pop Inn Cafe’s food business operator, left the blender dirty when he made Mia’s drink. A Prevention of Future Deaths report would go to the Food Standards Agency, Southwark Council and the cafe, Ballard said.

Inspection Concerns

Angela Bruno, the solicitor for Mia’s family, said concerns about the cafe had been raised before Mia’s death.

Bruno joined Mia’s parents, Chanel Spence and Adrian St Hilaire, on the U.K. talk show “Good Morning Britain,” whose hosts are Susanna Reid and Ed Balls.

Bruno claimed an inspection in 2020 found no allergy matrix at the cafe and that the business received a five-star rating anyway. She said an inspection two years later was “missed.”

Bruno said of the findings after Mia’s death in 2023: “Still no matrix, no allergy signs, other issues are raised with regard to contamination.”

Bruno also alleged that an inspection planned for September 2026 was not carried out. The Food Standards Agency’s website lists the cafe’s most recent five-star hygiene rating as 2024.

Southwark Council is the authority responsible for food safety inspections at the cafe.

Guilty Plea and £18,000 Fine

Long before the inquest opened, the criminal case had already closed. Yucel, then 47, entered a guilty plea to six food safety offenses that Southwark Council had brought against him. Among the charges were not making allergen advice available or visible to customers, not managing allergen contamination during food production, and serving food containing an allergenic ingredient that was not meant to be in it.

Croydon Magistrates’ Court fined him £18,000 and handed him a 100-hour community order on Jan. 24, 2025. Yucel is no longer the owner or operator of the Pop Inn Cafe.

Hazelnuts and almonds were present in the drink, the council said it believed at the time. Southwark councilor Natasha Ennin said in January 2025 that basic food safety rules, had the operator followed them, might have prevented the death, adding that officers would carry on working with local businesses so the rules are followed across the borough. An enforcement officer had visited the cafe several times to check that procedures designed to prevent a similar incident were being maintained, according to the council.

The judge, according to a lawyer for Yucel, described him as a man of previous good character; across 22 years, no previous incidents had been reported against him. The lawyer said Yucel pleaded guilty at the first opportunity, took immediate steps to educate himself in September and October 2023, and thinks of Mia and her family every day.

Mia’s parents said in a statement after the sentencing in January 2025 that food businesses nationwide would, they hoped, read the conviction and fine as a warning of what follows when food safety is not taken seriously.

A Call for Allergy Ratings

Spence said her daughter knew the milkshake contained nuts after just “two sips.” She said Mia had been to the cafe before. “It was a place she had gone a week before,” Spence explained.

Spence said the family was surprised to learn at the hearing that allergy management sits outside the food hygiene rating system. “When you see a five-star rating at a shop, you feel like, you know, you’re safe,” she said.

The parents want a new mark on the cafe window. They argue that hygiene ratings are silent on allergen handling, and they are seeking a separate, clearly displayed allergy management rating alongside the hygiene score so that allergy sufferers can judge where it is safe to eat.

Adrian St Hilaire said of a dedicated allergy rating: “Had that been in place, we’d be looking at a different outcome and a totally different story.”

The parents thanked the coroner and called the investigation careful and thorough. They said they were grateful that their daughter’s voice had been heard, and they believe Mia would still be alive had the local authority made sure the cafe understood and carried out its allergy responsibilities. “Mia was, and is, deeply loved and she will never be forgotten,” they said in a statement.

Michelle Victor, a partner at the law firm Leigh Day who leads the food safety team representing the family, said serious concerns arose from the evidence about the way the food service industry understands, manages and monitors food allergies. The family, she said, wants the Food Standards Agency and other authorities to look again at the framework that governs allergy safety and to weigh substantive reform.

Rebecca Sudworth, the Food Standards Agency’s director of food policy, said, “People have the right to know exactly what is in their food and drink,” adding that “it is a business’s legal duty to provide accurate allergen information.” She said the agency had recently issued new guidance for businesses on allergens, including the risk of cross-contact, and offers free allergy training.

Tanya Ednan-Laperouse, the founder of Natasha’s Foundation, said the inquest laid bare how far awareness, understanding and regulation of food allergies still have to go. She said allergies are not a preference or a choice but a serious and unpredictable medical condition. Her daughter, Natasha, died at 15 after an allergic reaction to sesame in a Pret baguette.
