The objectives of the research project are to:  (1) intervene to reduce children’s exposure to pesticides, including the development of a culturally appropriate intervention to break the take-home pathway; and (2) foster partnerships between academic researchers and the community in which information requested by the community and basic research deficiencies/gaps are translated into studies that address the health needs of both.
As a result of receipt of donor funds, we were able to increase the scope of work for this research project to include collection of additional biological specimens that will enhance the project further.  The additional tasks include:  (1) comparing the levels of organophosphorus pesticide (OP) parent compounds in the blood of adult farmworkers and non-farmworkers, adjusting for the multiple pathways; (2) compare levels of pesticide residues in saliva to those in urine and blood to determine reliability and validity of data and to assess more accurately the presence of OPs; (3) conduct blood analysis through finger sticks to ascertain cholinesterase levels; and (4) conduct analysis of buccal cell samples in adults and children of farmworkers and nonfarmworkers to gain a better understanding of the mechanisms of toxicity of OPs.

Progress Summary:

Data collection among farmworkers and non-farmworkers is complete. Local interviewers were hired and trained in study procedures. Study participants were recruited and data collection during the thinning, harvest, and non-spray seasons has been completed. During the thinning and non-spray seasons, data collection included an initial and follow-up survey, as well as collecting urine, venous blood, finger stick blood, buccal cells, saliva, and house and vehicle dust samples from farmworker and non-farmworker families as outlined in the study protocol.  During the harvest season, data collection included an initial and follow-up survey, as well as collecting urine and house and vehicle dust samples from farmworker and non-farmworker families as outlined in the study protocol.  The collected specimen samples were shipped to CDC and the University of Washington for analyses.  Analyses are currently under way.
All surveys have been data entered and a dataset for analyses is currently being compiled.
In the fall of 2006, we completed data collection among 50 warehouse worker adults/children.  Two local interviewers were trained to conduct an initial and follow-up survey among adults who worked in apple or pear packing plants.  Interviewers also collected urine samples from the adult and child and dust from the home and vehicle.  The collected specimen samples were shipped to the CDC and the University of Washington for analyses.  Data analyses are currently under way.
SIGNIFICANCE: Perhaps the most significant achievements are two: first, we provided empirical support for the take-home pathway of pesticides to the children of farmworkers; second, we demonstrated that the urinary metabolites of pesticides among children were directly associated with urinary metabolites of the farmworker in the household.
Once the data for this study are analyzed, we will be able to identify the parent compound of OP pesticides in blood.  We also will be able to examine cholinesterase levels in farmworkers (as opposed to pesticide handlers) and in their children.
Another innovative achievement is the ability and practice of providing accurate scientific data to farmworkers and growers in the Valley.  This led to numerous opportunities to address media throughout the state and country.
This study is one of the largest studies done with farmworkers and pesticide exposure that provides data from biomarkers as well as survey information.

Future Activities:

For the next funding period, we are working with the Centers for Disease Control and the University of Washington to analyze the biological samples.  Following data analyses, we plan to disseminate urinary metabolite results to adult and child farmworkers and non-farmworkers during a one-time house visit.  In addition to learning about their metabolite levels, participants will receive a handbook prepared by the Environmental Protection Agency, titled, “Protegiendo Nuestro Futuro” that provides information about the symptoms related to pesticide exposure, how to protect oneself from exposure in the workplace, what to do if exposed, and strategies to reduce pesticide exposure in the home.
We will work with the local Spanish-speaking radio station to disseminate messages on pesticide safety and protection.
