Report:

Effective immediately, the USDA's Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), is expanding the areas quarantined for citrus greening (Huanglongbing; HLB), caused by Candidatus Liberibacter asiaticus, in California. APHIS is expanding the quarantined area in San Diego County by approximately 86 square miles. APHIS is taking this action because of citrus greening detections in plant tissue samples collected from a residential property in San Diego County. There are 830 acres of commercial citrus impacted by this expansion.

APHIS is applying safeguarding measures on the interstate movement of regulated articles from the quarantined areas in California. These measures parallel the intrastate quarantines that CDFA established on September 16, 2024. This action is necessary to prevent the spread of citrus greening to non‑infested areas of the United States.

The specific changes to the quarantined areas in California can be found on the APHIS Citrus Greening website. APHIS will publish a notice of this change in the Federal Register.

Under IPPC Standards, 'Candidatus Liberibacter asiaticus' the agent that causes citrus greening is a pest that is present: not widely distributed and under official control  in the United States.
