Hospitals in the United Kingdom have documented several children with severe burns after playing with popular squishy toys.
Some of the toys exploded when people put them in a microwave device, causing burns and subjecting children to unidentified substances.
Physicians report the injuries stem from poisonous compounds in the pliable foam available on the internet.
Trading Standards officers in Gloucestershire have seized almost 2,000 the toys as part of a UK‑wide enforcement drive.
The seizure follows calls from councils and consumer groups to halt sales.
Authorities urge parents to throw away any squishy toy that has been heated or shows signs of chemical leakage.
