It is based on an interdisciplinary proposal which, ultimately, aims to subsidize sustainability-seeking production systems. The study area was Rural Settlement I in Sumare, Sao Paulo, Brazil, composed of 26 farming families, which basically produce vegetables, chiefly tomato crops. The model was applied in four consecutive phases: (i) the diagnosis of the health situation of the inhabitants of the area; (ii) their methods of handling agrochemicals and the most commonly used active ingredients; (iii) evaluation of clinical parameters as bioindicators; and (iv) group discussion with the farmers and members of their families about the development actions in the study area. The model adopted seems to be promising for early health evaluation of the family segment of the agricultural population, not implying excessive costs, and resulted in a significant change in the collective awareness of the community. 收起
