Current Insect and Disease Quarantines in Santa Clara County
Please note: The oriental fruit fly quarantine overrides the guidelines below if you're in the OFF quarantine zone. (For ACP section)
Quarantine on fruits and vegetables
Oriental fruit flies are a little larger than house flies. They damage fruit and vegetables by laying eggs inside them which hatch into maggots. They pose a huge threat to California's fruit industry. The insects often get into California when fruits and vegetables are illegally brought back from elsewhere in the world.
If you suspect you have found an oriental fruit fly or maggot in your fruit or vegetables, call the California Department of Food and Agriculture (CDFA) Pest Hotline: 1-800-491-1899. How to identify an oriental fruit fly
The quarantine will lifted if the eradication program is successful.
What the oriental fruit fly quarantine means
To prevent the spread of oriental fruit flies via infested homegrown fruits and vegetables, residents are urged not to move any fruits or vegetables that are botanically fruits from their property. Examples of vegetables that are fruits are tomatoes, peppers, cucumbers, and any type of melon.
Fruits and vegetables may be consumed or processed (i.e. juiced, frozen, cooked, dehydrated, ground in the garbage disposal, or composted) at the property of origin. If they are not consumed or processed, dispose of them by double-bagging and sealing them in plastic bags, then placing in the garbage bin for collection. Do not place them in green waste since that could transport eggs or larvae to a new area. Processed material may be shared off the property, including outside the quarantine zone.
Fruits and vegetables can be consumed on site at the garden or may be taken home for personal consumption. They may NOT be given away or sold to neighbors, friends, relatives, or customers unless processed (i.e. juiced, frozen, or cooked).
