Prepare your business for a fruit fly outbreak

Find out how to prepare and develop a plan so your business is ready for a fruit fly outbreak.

How a fruit fly outbreak can affect your business

A fruit fly outbreak can affect your business by changing the way that restricted fruit and vegetables are managed within a red outbreak area (Corrective Action Zone, or CAZ) and a yellow suspension area (Export Assurance Zone, or EAZ).

Restricted fruit and vegetables need to be treated, certified and transported securely, to make sure fruit fly is not spreading in infected fruit.

Your business will be impacted depending:

  • if you're in a Corrective Action Zone or Export Assurance Zone
  • if it's Mediterranean fruit fly or Queensland fruit fly
  • the timing of the outbreak through the season
  • where you're marketing and selling your fruit and vegetables.

Case studies

Examples of businesses who have planned what they will do if affected by a fruit fly outbreak.

Selling to one market and needing to apply treatments

Joe grows and packs 6ha of nectarines, peaches and apricots and has supplied the one wholesaler in Adelaide for the last 15 years.

If a fruit fly outbreak occurs and Joe’s property falls within a Corrective Action Zone or Export Assurance Zone, he'll need to treat his fruit in one of the approved methods to send to his agent in Adelaide.

Joe understands the requirements of ICA-07 Cold treatment disinfestation and plans to become accredited as soon as possible.

If the outbreak occurs close to harvest, he knows where he can have his fruit fumigated until he can send fruit under the accreditation.

Diversifying markets and reducing need for treatments

Joe’s neighbour, Jack, grows nectarines and peaches and supplies the same wholesaler in Adelaide.

For the last three years, Jack has been sending about 20% of his crop to wholesalers in Melbourne and Sydney. Even though the prices are a little less from time to time, Jack wanted to maintain the relationships with those wholesalers.

In the event of a Queensland fruit fly outbreak, Jack plans to send most of his fruit to Sydney and Melbourne, but still maintain the Adelaide market with a smaller volume of fruit which is fumigated before being shipped to Adelaide.

Jack believes that by sending most of his fruit to Sydney and Melbourne instead of Adelaide, he will avoid some of the costs associated with fumigating fruit being sent to Adelaide.

Located in Riverland Pest Free Area and ready to apply treatments

Cheryl is a table grape grower in the Riverland Pest Free Area, and sells to a local fruit and vegetable store and at weekend markets in Adelaide.

Cheryl maintains ICA-23 accreditation and packs all fruit in sealed cartons. Along with written approval from PIRSA, Cheryl is able to bring unsold and unopened cartons home from Adelaide.

In the event of an outbreak, Cheryl is ready to become accredited with ICA-20 for pre-harvest spray and post-harvest inspection of table grapes. While this will enable Cheryl to take grapes to weekend markets in Adelaide, unsold fruit can no longer be returned to the Riverland PFA. Grapes sold to the local fruit and vegetable store will also need to be fumigated, as the ICA-20 systems approach is not accepted for sales into the Riverland PFA (Fruit Fly Pest Free Area, or FF-PFA).
