Eradicated: Oriental fruit fly quarantine lifted in Contra Costa, but ag officials urge vigilance

The California Department of Food and Agriculture has declared an end to an Oriental fruit fly quarantine in Contra Costa County following the eradication of the invasive pest.

Thursday’s declaration comes nearly 10 months after state officials first detected populations of the Oriental fruit fly in the area and established a quarantine encompassing parts of the cities of Brentwood and Oakley and parts of Antioch, Bethel Island and Discovery Bay.
