2 accounts, one from South Australia (protocols need changes) and the other from Tasmania (fruit import ban lifted, below)


Due to summer mango fruit fly incursions

Tougher South Australia import restrictions

South Australia has strengthened its import requirements, following the discovery of fruit fly larvae in four consignments of Queensland mangoes sent to South Australia during the summer harvest. This of course threatened its fruit fly-free status. The reforms include a ban on fruit that has been heat-treated as well as stronger conditions for the use of a fumigation chemical treatment.

One of the infested mango consignments had been subjected to a hot-water treatment and another to methyl-bromide fumigation. Geoff Raven, the manager for plant and food standards at Biosecurity South Australia, said investigations found both treatments had met existing protocols for interstate certification. "They found that the chemical fumigators actually complied with the protocols and with the heat treatment, again there was no non-conformance. So the protocols were followed to the letter, which tells us that there's a problem with the protocols."

According to, the resulting suspension of heat treatments has virtually banned the trade of organic fruit to South Australia. Fruit treated by methyl-bromide must now have a temperature of 16Celsius, up from 12o, during the fumigation process. The higher temperature causes the larvae to become more active, which makes the pest more likely to ingest the chemical and die.

Biosecurity Queensland has revealed the consignment of infested mangoes treated by methyl-bromide had not originally been destined for South Australia, but Victoria.

Tasmania lifts ban on fruit from Melbourne fumigation facility

Tasmania's Biosecurity Department has lifted a ban on fruit and vegetable imports from a Melbourne plant, that was linked to a fruit fly outbreak. The ban on fresh produce imports from the Melbourne fumigation facility -linked to a fruit fly outbreak- was implemented earlier this year. Fruit and vegetables that passed through the plant were pulled from supermarket shelves across Tasmania in February after fly larvae were found in a nectarine.

According to, Biosecurity Tasmania boss Lloyd Klumpp said on Wednesday that the facility had passed an audit and imports into the state could resume.
