USDA APHIS added portions of Los Angeles, Orange, Riverside and San Bernardino counties to the quarantined areas. With the expansion of the Jurupa Valley and Riverside areas of Riverside and San Bernardino counties in the HLB quarantine area, CDFA merged the HLB quarantine boundaries, creating a single HLB quarantine. That quarantine expands across Los Angeles, Orange, Riverside and San Bernardino counties. In addition, APHIS is establishing a quarantine in a portion of San Diego County. APHIS is taking this action because of HLB detections in plant tissue samples collected from multiple locations during routine surveys in California.
