Coffee grown at Waialua Estate Coffee Farms and roasted at the Old Waialua Sugar Mill were placed under quarantine on Tuesday due to a coffee berry borer infestation.

The quarantine expands existing interisland restrictions to the Oahu locations effective immediately. Both sites are owned by Dole Foods.

The state said it had surveyed other small coffee farms in Waimanalo, Mauna­wili, Poamoho, Kunia and Tantalus, and found no infestations.

Under the quarantine, a permit is required to transport unroasted coffee beans, coffee plants and plant parts, used coffee bags and coffee harvesting equipment from infested islands to other non-infested areas or islands. Treatments and inspection by the state prior to shipping are also required.
