Eight-year-old Shana Richardson died after licking a commonly-sold white powder from her hand.

The ant killer she had used on insects near her home in St Leonards contained a chemical called lindane.

A pathologist concluded the small amount of this substance she ingested was linked to her death.

This tragedy adds force to a national campaign to ban the use of lindane, which has also been linked to birth defects and breast cancer.

Under a EU regulation, it will be withdrawn from sale in shops from June this year.

But anyone who has stocks of this potentially-deadly chemical should dispose of them well before then.
