A tragic incident in the London neighbourhood of Bermondsey has brought attention to food safety protocols, particularly concerning allergens. Twelve-year-old Mia Shay St Hilaire lost her life after consuming a milkshake at Pop Inn Cafe that had been contaminated with hazelnut residue, leading to a severe allergic reaction. The event occurred in August 2023 but garnered renewed interest following an investigation and subsequent court proceedings.

Mia was enjoying a day out with her aunt and sister when she ordered the milkshake. According to reports from the BBC, The Independent, and other media outlets, CCTV footage confirmed that the cafe’s operator, Baris Yucel, prepared the drink using a blender that had not been washed after its previous use. Tragically, this oversight proved fatal for Mia, who was rushed to the Evelina London Children’s Hospital but succumbed to her condition despite life-saving measures.
The Inner South London Coroner’s Court during the investigation found that the drink Mia consumed was cross-contaminated with hazelnut residue from a milkshake prepared earlier in the same uncleaned appliance. Assistant coroner Briony Ballard noted that Mia developed rapidly progressing anaphylaxis, collapsing at her aunt’s home shortly after her drink.
In January 2025, Yucel pleaded guilty to multiple food safety violations brought against him by Southwark Council. These offences included failing to provide visible allergen information to customers, not effectively managing allergen contamination during food preparation, and serving food that contained an allergenic ingredient that should not have been present. As a result, Yucel has been fined £18,000 and sentenced to a 100-hour community service order.
Council member Natasha Ennin expressed condolences on behalf of the local government and emphasised that Mia’s tragic death could have been prevented if basic safety protocols had been adhered to. She assured that the council would continue to engage with local food outlets to reinforce compliance with food safety regulations.
Although Yucel no longer operates the cafe, which now boasts a five-star food hygiene rating, Mia’s parents, Adrian St Hilaire and Chanel Spence, have called for significant reforms in the way food allergies are managed across the hospitality sector. They, alongside their legal representative Michelle Victor, urged the UK’s Food Standards Agency (FSA) to implement a system that clearly marks allergy management ratings at restaurants and cafes, much like the existing food hygiene ratings.
The St Hilaire family expressed their belief that the current system fails to adequately protect individuals with food allergies, stating that consumers often rely on food hygiene ratings to choose safe dining options. “There should be a separate, clearly displayed rating dedicated to allergy management,” said the family. They firmly believe that with proper regulatory changes, future tragedies can be averted.
Since Mia’s passing, her family has been vocal about their desire for her legacy to bring about significant changes that could save lives. “No family should ever have to lose a child in these circumstances,” they stated, adding that they hoped lessons learned from Mia’s experience would prevent similar incidents in the future.
In response to the concerns raised by Mia’s family, Rebecca Sudworth, Director of Food Policy at the FSA, extended her condolences and reiterated the importance of businesses taking allergen risks seriously. She stated that it is essential for consumers to have accurate information regarding allergens in their food and drink. The FSA has already begun to introduce new guidance aimed at improving allergy communication within the food service sector and offers free training resources to help businesses better understand their legal obligations.
The investigation into Mia Shay St Hilaire’s death has sparked a broader discussion regarding food safety and allergen management in the UK. As the debate continues, the hope remains that meaningful changes will be made to ensure the safety of all patrons, particularly those with severe food allergies. The St Hilaire family’s commitment to honouring Mia’s memory reflects a desire to prevent further tragedies and create a safer dining environment for everyone.
