An area quarantined for huanglongbing (HLB), also known as citrus greening disease, in California was recently expanded. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the California Department of Food and Agriculture (CDFA) issued the expansion.
The quarantined area in the Mission Viejo area of Orange County expanded by approximately 85 square miles. The expansion occurred because of citrus greening detections in plant tissue samples collected from residential properties in Los Angeles County. There is less than 1 acre 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 quarantine that CDFA established on Nov. 27, 2024. This action is necessary to prevent the spread of citrus greening disease 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.
APHIS recently announced another expansion of HLB quarantine areas in California’s Orange and Riverside counties by 31 square miles. Additional HLB quarantine expansions in the state went in to effect earlier this year.
More information on HLB quarantines may be obtained from National Policy Manager Abby Stillwell at abby.r.stilwell@usda.gov or 919-323-6296.
