OEHHA publishes the Guidelines for Physicians - a booklet that describes the state program of ChE monitoring for agricultural pesticide mixers/loaders/applicators who regularly handle toxicity Category I and II OP or CB pesticides. Physicians who are medical supervisors are required to possess a copy of these Guidelines and be familiar with its content.

You can download the PDF version of the full Guidelines for Physicians or a one-page summary of the Guidelines.

To obtain a printed version, contact OEHHA at or (510) 622-3170.

OEHHA is currently updating the online Medical Supervision training class and revising the Guidelines for Physicians, and the one-page summary of the Guidelines to reflect changes to Section 105206 of the Health and Safety Code that were recently enacted by the California legislature.
