Medfly Quarantine In Portion Of Alameda County
SACRAMENTO, September 6, 2024 — A portion of Alameda County has been placed under quarantine for the Mediterranean Fruit Fly (Medfly) following the detection of one wild mated female in Fremont. The USDA, the Alameda County Agricultural Commissioner, and CDFA are working collaboratively on this project.
CDFA has successfully eradicated each and every detected Medfly infestation in California history, dating back more than 40 years.
The quarantine area in Alameda County measures approximately 71 square miles, bordered on the north by CA-84; on the south by the boundary between Alameda-Santa Clara counties; on the west by the Don Edwards San Francisco Bay National Wildlife Refuge; and on the east by Calaveras Creek.
