People have been warned to immediately cease using an imported brand of eyeliners, after tests found the products contained lead.

NSW Health made the discovery after three children from the same family became sick.

NSW Health has warned people to cease using the Hashmi Surmi Special and Hashmi Kohl Aswad eyeliners immediately.

NSW Minister for Better Regulation Matt Kean said doctors found the children had elevated levels of lead in their blood, and reported it to the Public Health Unit.

“An investigation indicated the health concerns were likely to have been caused by one of the Hashmi brand eyeliners," he said.
