Study Links Slush Ice Drinks to Hospitalizations Among Young Children

LONDON, U.K. — A recent study reveals that at least 21 children were hospitalized in the U.K. and Ireland after consuming slush ice drinks containing glycerol. The findings, released on March 12, 2025, highlight potential risks associated with this popular treat.
The study indicates that children aged 2 to 6 became ‘acutely unwell’ shortly after consuming slushies over a 15-year period, from 2009 to 2024. Of the 21 hospitalized, 93% showed symptoms within 60 minutes of ingestion.
Symptoms varied from decreased consciousness to low blood sugar and potassium levels, with glycerol detected in all their urine samples. Notably, none had previous medical conditions that could have contributed to their illnesses. The research concludes that 95% of affected children did not experience recurring issues after ceasing slushie consumption.
In light of these results, the Advisory Committee on Safety (ADC) has issued strong recommendations for children under age 8, advising them to avoid slush drinks containing glycerol. ‘Consumption of slush ice drinks containing glycerol may cause a clinical syndrome of glycerol intoxication in young children,’ they stated. ‘This mimics inherited disorders of gluconeogenesis and glycerol metabolism.’
Moreover, the ADC cautions that children aged 4 and under should avoid these drinks entirely due to potential side effects, such as headaches and nausea, particularly with excessive consumption.
“While glycerol is generally considered safe for human consumption and is an authorized additive in the EU, there remains concern about the lack of transparency regarding glycerol concentrations in these products,” the ADC noted.
Rebecca Sudworth, director of policy at the Food Standards Agency (FSA), emphasized the need for parental awareness regarding the risks of slush drinks. ‘We continue to strongly encourage parents to follow our guidance, stating that slushie drinks should not be given to children under four years old,’ she stated. Sudworth also urged retailers to ensure parents are informed of these guidelines.
While symptoms of glycerol intoxication are typically mild, Sudworth reiterated the importance of vigilance, particularly with higher consumption. PEOPLE has reached out to the FSA for further comments but received no immediate response.
