Update: Public Release of Pesticide Incident Data

In July 2023, the EPA posted 10 years (2013-2022) of pesticide incident (see glossary) data on its website. This was done to increase transparency and provide a better understanding of pesticide exposures, including exposures to vulnerable populations.
 

  • The published datasets allow users to access raw data on pesticide incidents such as the incident date, the reason for the report (e.g., adverse effect, product defect), and the severity of the incident. It may also include information on the location of the incident, the pesticide product, and a description of the incident. However, the EPA has not verified the raw data for accuracy or completeness.
  • The EPA received information on pesticide incidents from pesticide manufacturers, state regulators for pesticide enforcement, individual emails, the National Pesticide Information Center, and American Association of Poison Control Centers.
  • Prior to this, the EPA only provided incident information to the public when responding to requests under the Freedom of Information Act or as an incident summary during the pesticide re-registration process. The EPA will now update the data monthly going forward.
  • Below is a summary of reported pesticide incidents from Maryland (2013-2022).
