London, England — A tragic incident involving a 12-year-old girl has reignited discussions on food safety and allergen management in the United Kingdom. Mia Shay St Hilaire suffered a fatal allergic reaction after consuming a contaminated milkshake at a south London café, where the blender used for preparation had not been properly cleaned.
The inquest into Mia’s death, conducted at the Inner South London Coroner’s Court, concluded on October 8, 2026. The coroner, Briony Ballard, highlighted significant failures in how the café managed allergen risks, pointing to missed opportunities to safeguard customers like Mia, who had a known hazelnut allergy.
Mia’s family, represented by solicitor Angela Bruno, expressed grave concerns regarding the café’s food safety practices prior to the girl’s passing. They allege previous inspections had overlooked critical safety protocols, including the absence of an allergy matrix, which is essential for managing food allergens. Bruno, alongside Mia’s parents, made a public appeal on a daytime talk show, underscoring that a routine inspection in 2020 failed to identify these issues yet still awarded the café a five-star hygiene rating.
On August 2023, during a visit to the Pop Inn Café on Southwark Park Road, Mia ordered a Twix milkshake, unaware it had been tainted with hazelnut residue from a previously prepared drink. The coroner revealed that Mia quickly succumbed to anaphylactic shock and collapsed later at her aunt’s home. Despite extensive emergency treatment and efforts to stabilize her at Evelina London Children’s Hospital, she tragically passed away.
Video footage from the café confirmed that Baris Yucel, the café’s operator at the time, neglected to clean the blender before preparing Mia’s drink. Following the inquest, Ballard stated that a Prevention of Future Deaths report would be forwarded to the Food Standards Agency, Southwark Council, and the café to address the significant lapses in food safety.
Yucel previously faced criminal charges stemming from six food safety violations related to allergen management. He pleaded guilty in January 2025, acknowledging failures such as not providing visible allergen information to customers and improperly handling allergenic ingredients during food preparation. As a result, he received an £18,000 fine and a community service order but is no longer associated with the café.
Mia’s parents, who reflected on their daughter’s awareness of allergens—claiming she recognized the milkshake’s hazard after just a few sips—are advocating for a more comprehensive system to assess allergen management in food establishments. They desire an additional allergy management rating to be displayed alongside existing hygiene marks to ensure better protections for those with food allergies.
Chanel Spence, Mia’s mother, emphasized the disconnect she felt when learning that allergy management was not included in hygiene ratings, stating that such ratings inaccurately convey a sense of safety. Her husband, Adrian St Hilaire, added that clearer labels could have potentially altered the tragic outcome.
The family praised the thorough investigation into Mia’s death, believing that her voice has been heard. They conveyed a heartfelt message, stating, “Mia was, and is, deeply loved and she will never be forgotten.”
As calls for reform grow, legal experts and advocates urge the Food Standards Agency to reconsider existing guidelines governing allergen safety. Rebecca Sudworth, a representative of the agency, reiterated that businesses are legally obligated to provide accurate allergen information and acknowledged the introduction of revised allergen guidance.
The inquest into Mia’s death has shone a light on the urgent need for enhanced awareness and regulation in the food service industry regarding food allergies. Tanya Ednan-Laperouse, founder of Natasha’s Foundation, underscored that understanding food allergies is critical, as they are a serious medical condition rather than a matter of preference.
