The U.S. Animal and Plant Health Inspection Service (APHIS) has established an Oriental fruit fly (Bactrocera dorsalis or OFF) quarantine in the Sacramento area of Sacramento County and Yolo County, California. 

The move comes in response to the confirmation of seven OFF from the Sacramento area by APHIS and the California Department of Food and Agriculture (CDFA) on August 21.

This was after CDFA and APHIS previously confirmed two adults. All OFF were detected in residential areas.

"APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from the area in order to prevent the spread of OFF to non-infested areas of the United States," it said.

"In cooperation with CDFA, APHIS is establishing a new quarantine area, which encompasses approximately 123 square miles of Sacramento County and neighboring Yolo County.

"Only small local host production occurs within the quarantine area and no major host crops are produced in the area. APHIS is working with CDFA and the Sacramento and Yolo County Agriculture Commissioners to respond to this detection following program survey and treatment protocols."
