Physicians report by phone to the local health officer. Each county has designated a phone number for pesticide illness reporting. See this form for the correct contact number in your area: https://www.cdpr.ca.gov/docs/pur/forms/purforms.htm
For occupational cases, physicians must also send a "Doctor's First Report" to the local health office and the State Department of Industrial Relations.
