The Food Standards Agency (FSA) has issued a clear warning to parents: children under the age of seven should not consume slush ice drinks, especially during the current heatwave. The agency highlights that these drinks contain glycerol (E422), a sugar substitute used to create the slush effect, which can cause adverse reactions in young children.
Health Risks for Young Children
According to the FSA, glycerol in slush drinks can lead to headaches, nausea, hypoglycemia (low blood sugar), shock, and even loss of consciousness in children under seven. The agency's guidance states that children aged seven to ten should have no more than one 350ml slush drink per day—equivalent to a standard can of fizzy drink.
The warning comes as the UK experiences record-breaking temperatures, with the North East reaching nearly 30°C in the past week. The FSA shared its advice on social media: "It's hot. If you're planning on cooling down with a slush drink, there are a few things parents should know."
Glycerol Content and Labeling
Glycerol is added to slush drinks to maintain their icy texture, but young children are more sensitive to its effects. The FSA advises parents to check labels or ask sellers whether a slush drink contains glycerol. If unsure, they recommend choosing an alternative drink.
The agency has also issued guidelines for manufacturers, urging them to use the minimum amount of glycerol necessary. Retailers are advised to display a visible warning at the point of sale: "Product contains glycerol. Should not be consumed by children under seven years of age and children under 10 should have a maximum of one 350ml drink per day."
Emergency Advice for Parents
If a child becomes unwell after consuming a slush drink—with symptoms such as headaches, nausea, or vomiting—the FSA advises giving them sugary food or drink immediately and calling 111 for medical advice. If the child becomes drowsy or confused, parents should call 999 for urgent medical attention. The agency also urges parents to contact their local authority if a child is medically diagnosed with glycerol intoxication from a slush drink, so an investigation can be carried out.
This guidance applies to all slush ice drinks, including ready-to-drink pouches and home kits containing glycerol in concentrates. The FSA emphasizes that the presence of glycerol should be clearly indicated on the label, and consumers should contact the manufacturer for further information if needed.
