Assessment of occupational hazards facing waste pickers to support a proper closure of a large open dump

Waste pickers are workers exposed to several occupational risks. This cross-sectional study investigated hazards associated with occupational accidents among waste pickers in the largest open dumpsite in Latin America before its closure. A survey was conducted with 999 waste pickers, collecting data on accidents and work characteristics. Among those interviewed, 686 (68.7%) of waste pickers reported having suffered accidents at work. Of these, 68.7% of them were related to exposure to sharp objects, and 62.5% were unable to work due to the accident. Work shift and work environment were significantly associated with accidents (p < 0.001). It indicates that workplace hazards are stronger predictors of accidents than personal characteristics. This article demonstrates the necessity for integrated and multi-sectoral strategies and surveillance systems that monitor environmental, animal and human health indicators aligned with the One Health approach in municipal solid waste management. This epidemiological study provides data to support dump closure in similar contexts, especially in countries in the Global South.
