Rural farming communities in the Western Cape province of South Africa are a vulnerable community who experience a diversity of hazardous exposures. One particular phenomenon that captures this conundrum is that of Foetal Alcohol Syndrome (FAS). FAS has been reported in 5 to 10% of school-going children in the province, which are rates that are the highest in the world, much higher than even so-called high-risk populations in North America. The direct antecedent of FAS, alcohol consumption in pregnancy, is itself a product of multiple behavioural, social and historical factors related to alcohol consumption by workers in agriculture in the region. However, consumption of alcohol during pregnancy may not be sufficient to explain these tremendously high rates, since the alcohol consumption of Western Cape mothers with FAS children is not as high as in other high-risk populations. There may thus be other factors common in this population which contribute individually, or synergistically, to increased risk of intra-uterine damage. Candidate exposures include pesticides, smoking and toxic contaminants within cheap wine drunk in the Western Cape, and genetic and nutritional deficits may also interact in the genesis of a public health calamity of this scale. Understanding the aetiology of the FAS epidemic in its fullest dimensions in the Western Cape, using the full range of exposure science characterization, is critical to successful interventions to reduce the burden of disease due to FAS in the region, particularly given that community-based interventions and upstream public health policies are likely to be the mainstay of FAS prevention.
