Where to Start with Pesticide Incidents

En español

Each state has their own pesticide regulatory agency that regulates most pesticide-related matters. They have the main responsibility to investigate pesticide incidents and may look into potential misuse, drift, and off-target impacts.

In many cases, it's beneficial to start by contacting your state pesticide regulatory agency.

  1. If you need medical attention right now, call the Poison Control Center at 800-222-1222.
    • If you are outside the U.S. and its territories, contact your country's poison center using the World Health Organization Poison Centre's Directory.
  2. If the situation involves an exposure at work, misapplication, or drift, call your state pesticide regulatory agency to report the occupational exposure.
  3. Consider reporting the incident to the product manufacturer. Manufacturers are required by law to submit reports of adverse effects to the Environmental Protection Agency (EPA).

ATTENTION: Physicians and Health Care Providers

By law, pesticide-related illness is a reportable condition in several states. If you are a health care provider treating a pesticide related incident, consider reading our Medical Case Profile on pesticide incident reporting. Call us at 800-858-7378 for assistance.
