The Food Standards Agency (FSA) has issued an updated warning that children under seven should not consume slush ice drinks containing glycerol, due to the risk of serious health issues including decreased consciousness and low blood sugar. Glycerol, a naturally occurring sugar substitute, prevents the drinks from freezing solid, but can cause glycerol intoxication syndrome in young children.
Symptoms of the syndrome include lactic acidosis and hypokalaemia (low potassium), which can lead to hospitalisation. The FSA revised its previous guidance – which advised against the drinks for children under four and limited consumption for those aged five to ten – ahead of an expected summer sales spike at play areas, leisure centres, and outdoor events.
Over the past three years, nine confirmed cases of glycerol intoxication in young children have led to hospital admissions in the UK. In March, paediatricians recommended that children under eight avoid such drinks after reviewing 21 cases of acute illness following consumption.
Prof Robin May, the FSA’s chief scientific adviser, said: “As we head into the summer holidays, we want parents to be aware of the potential risks… While side-effects are generally mild, they can, especially when consumed in large quantities over a short time, pose serious health risks to young children.” He added that the agency is working with industry to ensure appropriate warnings are in place.
The updated advice also covers ready-to-drink slushies in pouches and home kits containing glycerol concentrates. For children aged seven to ten, the FSA recommends no more than one 350ml serving, and urges extra caution during warmer months when slushie consumption typically rises.
