Huanglongbing Detection in Riverside County
Expands Quarantine in Portions of
Riverside, Orange and San Bernardino Counties 

SACRAMENTO, December 20, 2019 - A quarantine has been declared following the detection of the citrus disease Huanglongbing (HLB), or citrus greening, in multiple residential citrus trees within the City of Corona, Riverside County.  The United States Department of Agriculture (USDA), the Riverside County, Orange County, and San Bernardino County agricultural commissioners, and the California Department of Food and Agriculture (CDFA) are working collaboratively on this project.
     The 107-square mile quarantine area will link up with the east side of the existing quarantine in Los Angeles, Riverside, Orange, and San Bernardino counties, creating a contiguous 1,127-square-mile area. The new portion is bordered on the north by Chino Airport, on the south by Black Star Canyon, and on the east by Interstate 15.  HLB quarantine maps are available online at:  Please check this link for future quarantine expansions in these counties, should they occur.  Quarantines are already in place for HLB in portions of Los Angeles, Orange, Riverside, and San Bernardino counties. 
     The quarantine prohibits the movement of all citrus nursery stock or plant parts out of the quarantine area.  Provisions exist to allow the movement of commercially cleaned and packed citrus fruit.  Fruit that is not commercially cleaned and packed, including residential citrus, such as oranges, lemons, grapefruits, and kumquats, must not be moved from the property on which it is grown, although it may be processed and/or consumed on the premises.
