Up to one in five rental homes in Victoria alone could contain dangerous meth residue, according to explosive claims from an industry expert.

Speaking with the Herald Sun recently, Ryan Matthews, the chief executive of testing company Meth Screen, said the problem was more widespread than most Aussies realised.

He said skyrocketing ice use had led to more and more properties being contaminated by users — and estimated 20 per cent of rental properties and up to 15 per cent of owner-occupied homes in Victoria could contain unsafe levels of residue.

“The testing showed Victoria has the highest levels in the whole country,” Mr Matthews said.
