The relative success of some of California’s public health programs, such as WIC and Emergency Medi-Cal, among undocumented women farm laborers is supported in the present report by the remarkably similar prevalence of medical visits in this group as compared with documented women workers. This finding suggests that effective public health programs could be developed to reach male farm laborers, a group that has been largely ignored to date. Such a program could serve all workers, irrespective of immigration status.
