The Children's Organic Diet Study

Project Summary: 

The Children's Organic Diet study evaluates the contribution of pesticides on food to children’s overall pesticide exposure, and to determine whether this differs between urban and agricultural regions.
The study investigates:

  • Whether children who eat only organic food have lower organophosphate (OP) pesticide metabolite levels in their urine.
    Whether children living in Oakland, CA, (an urban community) have lower pesticide levels compared to children living in Salinas, CA (an agricultural community)
  • Whether the proportion of exposure that comes from diet is different in each community

How do we measure pesticide exposure? We measured the levels of breakdown products (also called “metabolites”) of organophosphate (OP) pesticides in children’s urine.
Exposure Studied:

  • Organophosphate (OP) and other pesticides
Main Findings: 

Findings from these and other exposure studies can be found on the CERCH Findings page:

Policy, Practice or Research Impacts: 

The importance of this study is that it will help clarify the primary route or routes of pesticide exposures to US children. This knowledge is critical if we are to reduce families' exposures to pesticides.
