QUEENSLAND fruit fly outbreaks have the potential to disrupt domestic and export fruit sales, the Victorian Agriculture Minister warned today.

Minister for Agriculture and Food Security Peter Walsh said the state was facing one of its worst Queensland fruit fly outbreaks.

The outbreak has been detected in Sunraysia, the Goulburn Valley and North East Victoria and parts of East Gippsland.

"There are now almost 60 outbreaks either declared or being declared across the state, many of which are in Victoria’s premium fruit-growing regions," Mr Walsh said.

"The widespread warm, humid conditions across Victoria in recent weeks have been ideal for fruit fly activity and make it one of the worst seasons for outbreak in more than 60 years.

"Queensland fruit fly has the ability to disrupt some domestic and international markets and impose significant additional treatment costs on fruit producers." 

He said the government was working with industry groups but co-operation from all Victorians was crucial.

"Local communities have a key role to play in minimising the impact of the pest by vigilantly monitoring their backyard fruit trees and notifying the Department of Primary Industries immediately if they find any signs of fruit fly."

He also warned travellers that carrying infected fruit into fruit producing areas attracted significant fines.
