Public health was once synonymous with environmental health. However, as living conditions improved the two fields diverged. Environmental factors are again re-emerging as hazards human health. Increasing global reliance on agricultural and veterinary chemicals (AgVets) over recent decades has is now a serious public health concern. Evidence of their toxicity has prompted international efforts to minimize, monitor and manage exposure risks. Direct involvement of the primary health care workforce is seen as critical to this process, yet little data exists on the health burden on Australian rural communities imposed by these chemicals.
The study presented here attempts to explore the impact of these chemicals on two rural communities in Victoria, and ascertain the how the existing primary heath care system responds to AgVet exposure issues. Health determinants are complex, and inter-related, and the client �provider interface is not an entity acting in isolation from other frameworks. The provider-client service relationship has evolved against a background of legislation and provider training. Many external factors also impinge, such as the structure and focus of the health sector, and Australia�s systematic approach to environmental and chemical management. Examination of this underlying infrastructure in Australia provided the background against which the issue of exposure to agricultural and veterinary chemicals was explored. A brief summary of international developments in this area served to provide insight as to what interventions may be introduced to address the issue of chemical exposure.
A CATI (Computer Assisted Telephone Interview) survey of 1050 households sought the perspectives from two Victorian agricultural communities to gather self-reported AgVet exposure patterns and health data, and whether respondents perceived their health problems were linked to exposure. Respondents were also asked to comment on the primary health care service experiences from local providers, and which services they preferred to seek for health advice. Perspectives were then sought from all primary health care providers servicing these communities. Information was sought on their level of expertise in diagnosing, and managing exposure related illness, via face-to-face interviews, focus groups and paper surveys.
The study revealed rural communities have a long history of hazardous exposure to toxic AgVets. Awareness of toxicity risks is growing, yet further scope exists to improve safe handling of chemicals. High levels of illnesses known be associated with AgVet exposure exist among rural populations. Many believe their own ill-health is linked to exposure, and express strong dissatisfaction with the apparent lack of environmental health expertise especially among their GPs. Health providers demonstrated limited understanding of the health impacts of AgVet exposure.
The lack of environmental health expertise among the existing primary health care workforce means that health conditions associated with exposure to AgVets are not being identified, and the absence of health intelligence hampers health planning. In Australia, the health, environment and primary industries sectors function in effect, as distinct silos, with little cross-fertilisation. The United States has combined its agricultural chemical legislative authority to develop a focus on human health, establish direct links, and biomonitoring programs to protect human heath. The U.S. has also developed environmental health expertise at the primary health care level to address community needs as they arise. Strategies are required in Australia to connect the environment, chemical management and health portfolios, with respect to the emerging environmental issues of chemical exposure. There is a need also in Australia to inject environmental health capacity into the primary health care practice.
