An assessment in Addis Ababa, Ethiopia, analyzed 210 lettuce and 90 irrigation water samples for faecal coliform and helminth eggs. Faecal coliform levels ranged from 4.29-5.61 log10 MPN 100 ml−1 in water and 3.46-5.03 log10 MPN 100 g−1 on lettuce, exceeding WHO recommendations. Helminth eggs were detected in 80% of water and 61% of lettuce samples, also exceeding standards. While washing methods reduced contamination, levels remained in a potential risk range.
