Mia Shay St. Hilaire, a 12-year-old girl with a severe nut allergy, died in London after drinking a milkshake contaminated with hazelnuts at Pop Inn cafe. The cafe owner, Baris Yucel, used the same blender without cleaning it after making another drink containing hazelnuts. Mia developed anaphylaxis and was hospitalized but later passed away despite emergency treatment. Yucel was fined £18,000 and ordered to serve 100 hours of community service for failing to manage food allergens properly.

Story summary
In August 2023, 12-year-old Mia St Hilaire died after drinking a Twix milkshake at the Pop Inn Cafe in Bermondsey, south-east London. The coroner found that the drink was contaminated with hazelnut residue from a previous Kinder Bueno milkshake prepared in an unwashed blender by cafe operator Baris Yucel. Mia, who had a tree nut allergy, developed anaphylaxis and died despite emergency medical treatment at the Evelina London Children’s Hospital. In January 2025, Yucel was fined £18,000 and given 100 hours of community service for admitting six criminal charges under the Food Safety Act, including not managing allergen contamination properly. Mia's parents called for better regulation to protect people with food allergies after her inquest concluded on Thursday.
