Mia Shay St Hilaire’s parents are demanding allergy management ratings for restaurants after a London cafe’s unwashed blender killed their 12-year-old daughter.
Adrian St Hilaire and Chanel Spence spoke out after an inquest at Inner South London Coroner’s Court concluded Thursday, Oct. 8, that their daughter died from cross-contamination at the Pop Inn Cafe in Bermondsey. Mia, who had a hazelnut allergy, collapsed at her aunt’s home last August after drinking a milkshake made in a blender still carrying nut residue from a previous order.

Assistant coroner Briony Ballard determined the drink “had been cross-contaminated with hazelnut residue” from prior use. Mia developed “rapidly progressing anaphylaxis” despite life-saving efforts and died at Evelina London Children’s Hospital.
CCTV footage showed cafe operator Baris Yucel, 47, preparing the milkshake without washing the blender first. Southwark Council prosecuted him for six offenses including failing to display allergen advice, mismanaging contamination risks, and serving food containing an undeclared allergen.
Yucel pleaded guilty in January 2025. District Judge Dean fined him £18,000 ($24,000) and imposed a 100-hour community order, noting his previous good character and 22 years without incidents in the food business. Yucel’s lawyer told the Southwark News the judge accepted he had shown “genuine remorse.” Yucel no longer owns or operates the cafe, which retains a five-star food hygiene rating.
Mia’s parents issued a blistering statement about regulatory failure. “If the local authority had ensured that the cafe’s allergy management responsibilities had been properly understood, and put into practice, we believe Mia would still be alive today,” they said.
Their lawyer, Michelle Victor, joined the call for systemic change. “Consumers rely on food hygiene ratings when deciding where it is safe to eat, but they do not tell us anything about the way a food business runs allergy management systems,” she said alongside the family.

Southwark Council cabinet member Natasha Ennin addressed the case publicly. “What happened to Mia-Shay is a tragedy and my heart goes out to her family and the people who loved her,” she said.
The Food Standards Agency is now under pressure to reform its rating system. Rebecca Sudworth, the FSA’s Director of Food Policy, said in a statement: “Food businesses must take allergen risks seriously, every time.” She noted the agency has issued new guidance on cross-contact risks and offers free allergy training to businesses.
The current UK food hygiene rating scheme scores cleanliness and safety procedures but carries no specific marker for how establishments handle allergens—a gap Mia’s family wants closed.
Mia had visited the Pop Inn Cafe with her aunt and sister in August 2023, a routine outing that turned fatal because of a single unwashed appliance. The inquest’s conclusion has amplified longstanding concerns from allergy advocates that existing regulations leave diners vulnerable despite high-profile deaths.
