This cross-sectional study in Accra, Ghana, assessed faecal exposure among 80 farm workers during dry and wet seasons, analyzing water and soil samples for E. coli. The results showed that while irrigation water was highly contaminated (5.6 Log E. coli/100 ml), exposure to farm soil (2.3 Log E. coli/g) was the key risk pathway due to soil-to-mouth events, with 53% of farmers experiencing such events daily. The estimated norovirus infection risk to farmers was found to be higher than guidelines set by the WHO, indicating that exposure to soil is a critical pathway of pathogen risk in wastewater farmers, exceeding recommended health targets.
