[BDSP. Notice produite par INIST-CNRS A3I74R0x. Diffusion soumise à autorisation]. A screening-level quantitative microbial risk assessment (QMRA) was undertaken for a urine separating sewerage system. Exposures evaluated included the handling of stored and unstored urine as well as consumption of crops fertilised with urine. Faecal cross-contamination was the source of risk and Campylobacter jejuni, Cryptosporidium parvum and rotavirus were the organisms chosen to represent different groups of enteric pathogens. Accidental ingestion of unstored urine implied a high risk (Pinf=0.56) for infection from rotavirus whereas the risks for infection from bacteria and protozoa were approximately 1 : 10 000. After six months storage at 20°C the risk for viral infections by accidental ingestion of 1 ml of urine was
