Candidatus Liberibacter asiaticus (Citrus Greening) - Quarantined Area Expanded in Louisiana

Country: United States

Title: Candidatus Liberibacter asiaticus (Citrus Greening) - Quarantined Area Expanded in Louisiana

Angela McMellen Brannigan, Citrus Health Response Program National Coordinator, at 301-851-2314.


Effectively immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the Louisiana Department of Agriculture and Forestry (LDAF) and the Louisiana citrus industry, is expanding the area quarantined for citrus greening (or huanglongbing) to include all of Jefferson Parish. APHIS is taking this action because of the positive detection of citrus greening in plant tissue samples collected from a residential property in Metairie, Jefferson Parish, Louisiana.

APHIS is applying safeguarding measures on the interstate movement of regulated articles from the regulated areas in Jefferson Parish. These measures parallel the intrastate quarantine that the LDAF initiated on March 3. This action is necessary to prevent the spread of citrus greening to non-infested areas of the United States.

The specific changes to the regulated areas in Louisiana can be found at:

APHIS will publish a notice of this change in the Federal Register.

Under IPPC Standards, 'Candidatus Liberibacter asiaticus' is considered to be a pest that is present, only in some areas, and subject to official control to limit its spread in the United States.
