ABSTRACT
The working and living environments of farmworkers put them and their families at risk for pesticide exposure and, consequently, immediate and long-term health effects. In this study, visual materials for a pesticide toxicology safety and health curriculum were constructed by engaging farmworkers in various stages of symbol development. Twenty-seven farmworkers in two states participated in this descriptive case study through focused small group discussions and interviews. Our findings support the importance of vivid and realistic symbols, the effectiveness of a traffic-light symbol in communicating technical information to farmworkers, and the need to engage low-literacy end-users in the production of educational materials. This work informs the development of curricula for other vulnerable populations pertaining to a variety of health-related topics, as well as discussions surrounding regulatory proposals to revise the United States Worker Protection Standard.
