Encourages the department of agriculture, the department of health, and the department of labor and industries to begin an investigation of suspected human exposure to pesticide on the same day the department learns of the suspected human exposure and requires the investigation to begin no later than forty-eight hours after the department learns of the suspected human exposure.

Requires the department of agriculture, the department of health, and the department of labor and industries to agree to and designate one of the three agencies as the lead agency for each investigation of an alleged human exposure to pesticide so that people affected by the exposure or an investigation know which agency to contact.
