Fruit & Vegetable Quarantine in Santa Clara County

The Oriental Fruit Fly (OFF) has been detected in Santa Clara County. OFF is a threat to both home and commercial growers. Homeowners are asked not to move fruits and vegetables from their property. (Map of quarantine area) The infestations are likely the result of contraband fruit or vegetables brought into California by travelers. Be responsible and don't smuggle fruit or vegetable into the state.
