  • APHIS Expands the Citrus Greening (Huanglongbing) Quarantined Area in California

    The Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), is expanding the citrus greening (Huanglongbing; HLB) quarantined area in California. APHIS is adding one square mile to the Santa Paula quarantined area in Ventura County, which impacts 151.7 acres of commercial citrus. APHIS is adding 10 square miles to the quarantined area in Riverside and San Diego Counties, which impacts 121.5 acres of commercial citrus. This measure parallels the intrastate quarantine that CDFA established on July 15, 2026. APHIS is taking this action because plant tissue samples from residential properties tested positive for Candidatus Liberibacter asiaticus, the causal agent of HLB.

    APHIS is applying safeguarding measures outlined in 7 Code of Federal Regulations (CFR) 301.76 through 301.76-11 and associated Federal Orders that govern interstate movement of regulated articles from the quarantined areas. This action helps prevent HLB from spreading to areas that are not currently infested.

    For updated maps and details, visit the APHIS Citrus Greening and Asian Citrus Psyllid webpage. APHIS will also publish a notice of this change in the “Federal Register.”

  • APHIS Expands Sweet Orange Scab Quarantine

    Effective Aug. 19, USDA’s Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), expanded the area quarantined for sweet orange scab (SOS) in the Burbank, Los Angeles and Long Beach areas of Los Angeles County and the Anaheim and Garden Grove areas of Orange County. SOS is a disease caused by the fungus Elsinöe australis. APHIS is expanding the quarantined area by 110 square miles in Los Angeles County and 67 square miles in Orange County. APHIS is taking this action because of SOS detections in plant tissue samples collected from residential properties in Los Angeles and Orange Counties. There are 2.5 acres of commercial citrus impacted by the Anaheim and Garden Grove area expansion

    APHIS is applying safeguarding measures outlined in Federal Order DA-2024-34 pertaining to the interstate movement of regulated articles from the quarantined areas in California. This measure parallels the intrastate quarantine that CDFA established on June 18, 2026. This action is necessary to prevent the spread of SOS to non-infested areas of the United States

    The APHIS Sweet Orange Scab webpage has information on this disease, Federal Orders, APHIS approved packinghouse procedures, and a description of current Federal SOS quarantined areas.

California continues to be a leader in what we grow and how we grow it.”

  • Mexican Fruit Fly Quarantine in Portion of SD County

    A portion of San Diego County has been placed under quarantine for the Mexican fruit fly following the detection of one mated female fly in and around the unincorporated community of Spring Valley. This new quarantine will overlap a portion of the existing La Mesa Mexican Fruit Fly quarantine by 19 square miles. The USDA, the San Diego County Agricultural Commissioner and the CDFA are working collaboratively on this project.

    The new quarantine area in San Diego County measures 76 square miles, bordered on the north by El Cajon; on the south by Proctor Valley; on the west by Lemon Grove; and on the east by McGinty Mountain. A link to the quarantine map may be found here: www.cdfa.ca.gov/plant/mexfly/regulation.html.

    Sterile male Mexican fruit flies will be released in the area as part of the eradication effort. The release rate will be up to approximately 250,000 males per square mile per week in an area up to 50 square miles around the infestation.

    The quarantine will affect growers, wholesalers and retailers of susceptible fruit in the area as well as nurseries that grow and sell Mexican fruit fly host plants. The quarantine will also affect local residents; home gardeners are urged to consume homegrown produce on site and not move it from their property.  These actions protect against the spread of the infestation to nearby regions where it could affect California’s food supply and backyard gardens and landscapes.

    The Mexican fruit fly can lay its eggs in and infest more than 50 types of fruits and vegetables, severely impacting California agricultural exports and backyard gardens alike. For more information on the pest, please see the pest profile at: www.cdfa.ca.gov/plant/go/MexFly. Residents who believe their fruits and vegetables may be infested with fruit fly larvae are encouraged to call the state’s toll-free Pest Hotline at 1-800-491-1899.

    The eradication approach used in the Spring Valley area of San Diego County is the standard program used by CDFA and it is the safest and most effective and efficient response program available.

    While fruit flies and other invasive species that threaten California’s crops and natural environment are sometimes detected in agricultural areas, the vast majority are found in urban and suburban communities. The most common pathway for these invasive species to enter our state is by “hitchhiking” in fruits and vegetables brought back illegally by travelers as they return from infested regions of the world. To help protect California’s agriculture and natural resources, CDFA urges travelers to follow the Don’t Pack a Pest program guidelines (www.dontpackapest.com). — Story Contributed by the California Department of Food and Agriculture
