The Mayor of the Indigo Shire, Bernard Gaffney, has asked the council to begin discussions with North East Water about adding fluoride to water supplies across the shire.

Councillor Gaffney brought the notice of motion before the council at its meeting last night.

He said Chiltern, Barnawartha, Kiewa and Tangambalanga already received fluoride in their water supply but Beechworth, Yackandandah, Rutherglen and Wahgunyah did not.

Cr Gaffney wants to start a conversation with North East Water to change that.

He said research showed fluoride had strong benefits in preventing tooth decay and that there was not enough evidence to suggest it was harmful to human health.

Cr Gaffney conceded fluoridation was an emotive issue and that wide community consultation would need to take place before any decision was made.
