Federal agriculture officials on Nov. 25 announced the expansions of the areas quarantined for sweet orange scab (SOS) and huanglongbing (HLB) diseases in California. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the California Department of Food and Agriculture (CDFA) enacted the expansions.
SOS
The SOS quarantined area has been expanded by 5 square miles in the Tustin area of Orange County. An SOS detection in a plant tissue sample collected from a residential property in Orange County triggered the expansion, but it does not impact commercial citrus.

APHIS is applying safeguarding measures pertaining to the interstate movement of regulated articles from the quarantined areas in California. This measure parallels the intrastate quarantine that CDFA established on Nov. 14. This action is necessary to prevent the spread of SOS to non-infested areas of the United States.

HLB
The HLB quarantine in the Capistrano Beach area of Orange County has been expanded by 29 square miles and the Murrieta area of Riverside County by 129 square miles. These measures parallel the intrastate quarantines that CDFA established on Oct. 22. APHIS is taking this action because of HLB detections in plant tissue samples collected from residential properties in Orange and Riverside counties.
