USA Flag Xanthomonas spp. (Citrus Canker):  APHIS Adds Portions of Brazoria, Fort Bend, and Harris Counties in Texas to the Domestic Quarantine Area
Date posted: 09/23/2019
Contact: Angela McMellen-Brannigan, Citrus Health Response Program National Policy Manager, at 301-851-2314.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the area quarantined for citrus canker in Texas to include portions of Brazoria and Harris Counties in and near Pearland and additional portions of Fort Bend and Harris Counties in and near Richmond to prevent the spread of the disease. 

On May 18, 2018, APHIS confirmed the positive identification of citrus canker in a residential citrus tree in Pearland, Texas following a homeowner report. The Texas Department of Agriculture (TDA) completed a delimiting survey around the location and found 22 additional citrus trees positive for citrus canker. APHIS confirmed citrus canker in additional trees around the existing Richmond Citrus Canker Quarantine area during routine surveys. TDA established an intrastate quarantine area for citrus canker that parallels the federal citrus canker regulatory requirements as specified in 7 Code of Federal Regulations (CFR) §301.75.

Under the citrus canker quarantine regulations, the interstate movement of citrus plants and plant parts, other than commercially packed and disinfected citrus fruit, remains prohibited. Citrus nursery stock that is moved in accordance with regulations as noted in 7 CFR 301.75-6 may move from areas quarantined for citrus canker.

Under IPPC Standards, species of Xanthomonas that cause citrus canker are considered to be pests that are present, only in some areas in Florida, Louisiana, and Texas and subject to official control in the United States.
