Aimed at health care providers, but open to the general public, this course presents the current scientific evidence regarding health risks for children exposed to organophosphate pesticides (OPs). This information is needed to understand potential risks to pediatric patients and inform clinical problem solving regarding pesticide exposure.

The course takes ~ 1.5 hours to complete.


The goals of this educational activity are to:

  • Increase the knowledge of health care providers, especially pediatricians, about the special susceptibilities of children to pesticides, particularly organophosphate pesticides
  • Increase competency to recognize and respond to childhood pesticide-related illness.


After completing this educational activity, the reader should be able to:

  • Identify the routes and patterns of exposure that place children at risk for higher dose exposure to pesticides.
  • Discern the importance of taking an environmental exposure history for timely diagnosis of childhood illness due to pesticides.
  • Recognize the signs and symptoms of acute organophosphate poisoning in children, with attention to how presentation may differ from that seen in adults.
  • Describe the public health importance of sentinel event reporting of pesticide-related illnesses, and know how to report such events.
  • Understand the current evidence for long-term sequelae of acute and chronic organophosphate exposures during childhood.
  • Provide anticipatory guidance that enables patients to limit childhood pesticide exposures.


Feel free to test yourself! Test results will be used to evaluate the effectiveness of this course & improve future online training efforts.
