Why It Matters
The Coroners Service has completed an investigation into the death of a 12-year-old girl, finding that there was negligence in the preparation of the drink.
In the UK, a milkshake made in an unwashed blender killed a London schoolgirl. The Daily Star writes about this.
In August 2023, 12-year-old Mia Shay St. Hilaire went to the Pop Inn Cafe with her aunt and sister. The girl ordered a Twix milkshake. After a few sips, she had a severe allergic reaction. They could not save the girl. Investigators found traces of hazelnuts in the cocktail, to which Saint-Hilaire was allergic. However, this nut was not included in the cocktail recipe.
The coroners service completed a formal investigation in October. From his results it follows that the hazelnuts got into the girl’s smoothie from a poorly washed blender. CCTV footage showed that cafe employee Baris Yucel did not wash the device before preparing the young British woman’s cocktail. Before that, he prepared a Kinder Bueno cocktail, which contains hazelnuts.
Yucel pleaded guilty back in January 2025 and was sentenced to a large fine and 100 hours of community service. A coroner's investigation has finally determined how hazelnuts got into the St. Hilaire cocktail. The schoolgirl's family thanked the participants in the investigation and called on the authorities to create a special rating of establishments for allergy sufferers, similar to the rating of sanitary conditions.
