Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the area quarantined for citrus canker in Louisiana.

APHIS established a quarantine on February 10, 2014, following the positive identification of Xanthomonas spp., the bacterial causal agent of citrus canker, from a sweet orange tree located in New Orleans, Louisiana. APHIS further updated this quarantine on June 2, 2016, to add portions of several parishes.

A Federal Order adds the entire parishes of Jefferson, Lafourche, Plaquemines, St. Charles, St. James, and St. John to the citrus canker (Xanthomonas spp.) quarantine in Louisiana. Louisiana has established an intrastate quarantine area for citrus canker that parallels the federal citrus canker regulatory requirements specified in 7 Code of Federal Regulations (CFR) 301.75.

Under the current citrus canker quarantine regulations, the interstate movement of citrus plants and plant parts, other than commercially packed and disinfected citrus fruit, remains prohibited with the following exception: citrus nursery stock that is moved in accordance with regulations contained in 7 CFR 301.76 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 and Louisiana, and subject to official control in the United States.
