Objectives Unregulated use of pesticides continues in developing countries in the presence of illiteracy and limited safety training and practices. This paper describes training and safety practices when mixing and spraying pesticides, and acetylcholinesterase levels among women farmers in KwaZulu-Natal, South Africa. Methods A cross-sectional study conducted in women working in small-scale agriculture in rural KwaZulu-Natal, South Africa in 2006 assessed pesticide training and safety practices using a questionnaire survey and measured acetylcholinesterase levels in 803 women. Three components of safety behaviour were identified through principle component analysis and described. Results The mean age of participants was 41.8 years (range 18e82 years) with a mean of 6.9 years (range 1e12 years) of education among school attendees. Among the 803 women included, 366 (45.6%) were the primary sprayers on their farm. Only 16.4% of the sprayers had ever attended a pesticide training course and only 18.0% reported ever reading pesticide labels. Of the women using some form of protective equipment, 56.7% and 54.9% reported doing so when mixing and spraying pesticides, respectively. The mean acetylcholinesterase level corrected for haemoglobin among study participants was 28.9 U/g Hb (95% CI 28.4 to 29.4). Conclusion Women working in small-scale agriculture in rural KwaZulu-Natal with limited access to pesticide training observe few safety practices when mixing and spraying pesticides.

Pesticide exposures of women in developing countries are aggravated by economic policy changes associated with structural adjustment programs and globalization. Women in these countries, particularly in the agricultural sector, are increasingly exposed. Since they are concentrated in the most marginal positions in the formal and informal workforces, and production is organized in a gender-specific way, opportunities for women to control their exposures are limited. Data from developing countries show that: 1) women's exposures to pesticides are significantly higher than is recognized; 2) poisonings and other pesticide-related injuries are greatly underestimated for women; 3) for a given adverse outcome from exposure, the experience of that outcome is gender-discriminatory; 4) erroneous risk perception increases women's exposures. The hiatus in knowledge of gender-specific exposures and effects is related to gender biases in the nature of epidemiologic inquiry and in the literature, and the gendered nature of health workers' practices and surveillance. Recommendations are made for strong, independent organizations that provide opportunities for women to control their environments, and the factors affecting their health, as well as gender-sensitive research to address the particularities of women's pesticide exposures.

The increasing number and the morbidity and mortality of acute paediatric pesticide exposure and poisoning is of great concern. Furthermore, the magnitude of the problem is masked by inadequate notification with the relevant health authorities.
