Mia St Hilaire Allergy Inquest Shines Light on Food Safety Gaps
Mia Shay St Hilaire, a 12-year-old girl from Sydenham, died in August 2023 after drinking a milkshake contaminated with hazelnut residue at the Pop Inn Cafe in Bermondsey, south-east London. Assistant coroner Briony Ballard examined the evidence at the London Inner South Coroner’s Court, concluding that an unwashed blender caused the rapid anaphylaxis that took the young girl’s life. In the wake of the tragedy, her parents, Adrian St Hilaire and Chanel Spence, alongside prominent safety advocates, are calling for a dedicated, clearly displayed allergy rating system across the food service industry to protect vulnerable consumers.
Café Operator Fined £18,000 for Allergen Failures
Southwark Council’s food and safety team led an investigation revealing that the milkshake prepared for Mia contained both hazelnuts and almonds. CCTV footage presented during legal proceedings showed the café operator, Baris Yucel, failing to clean the blender properly before making the drink. Following these events, Yucel admitted guilt to half a dozen food safety violations, which involved omitting visible allergen guidance for patrons, failing to properly control cross-contamination of allergens, and providing a dish containing an allergen that ought not to have been present. For these offenses, Yucel was fined £18,000 and given a 100-hour community order.
Coroner Rules Prior Care Failings Did Not Cause Death
The examination into Mia’s death highlighted shortcomings and missed chances in her prior allergy treatment, such as the lapse in specialized ongoing supervision and the dispensing of an EpiPen with a lower dosage than appropriate for her weight. However, coroner Briony Ballard determined those failings did not cause or contribute to Mia’s death. Expert evidence established that neither a timely dose of adrenaline nor a higher-strength injector would have altered the fatal outcome. Ballard announced she will issue a Prevention of Future Deaths report to the Food Standards Agency, Southwark Council, and the cafe, raising concerns about allergy responsibilities being divided between food hygiene and food standards inspections.

Parents Campaign for a Dedicated Allergy Rating System
Reflecting on the tragedy, Mia’s parents argued that existing food hygiene ratings fail to communicate how businesses manage allergens. Adrian St Hilaire and Chanel Spence stated that consumers rely on hygiene scores without knowing anything about the way a food business runs allergy management systems. They urged regulators to establish a separate, clearly displayed rating dedicated specifically to allergy management, similar to standard hygiene scores, so that families can make informed dining choices. Michelle Victor, a Leigh Day partner representing the family, noted that the case exposed weaknesses across the broader food service industry regarding allergen enforcement.
Foundation Advocates Urge Urgent Regulatory Reform
Tanya Ednan-Laperouse, founder of Natasha’s Foundation—named after her own 15-year-old daughter who died from a sesame allergy in a Pret A Manger baguette—emphasized that food allergies represent a serious, unpredictable medical condition that can prove fatal. Ednan-Laperouse stated that the inquest into Mia’s death illustrates how far society must go to improve awareness, understanding, and regulation. Natasha’s Foundation continues working with businesses, schools, communities, and the government to ensure allergen controls receive importance comparable to food hygiene.
