A risk of rotavirus infection of 10-2 per person per year (pppy) was used as the reference level of acceptable risk. Using the model scenario of involuntary soil ingestion for restricted irrigation, the risk of rotavirus infection is ~10-2 pppy when the wastewater contains \u2264106Escherichia coli per 100\u00a0ml and when local agricultural practices are highly mechanised. For labour-intensive agriculture the risk of rotavirus infection is ~10-2 pppy when the wastewater contains \u2264105E. coli per 100\u00a0ml; however, the wastewater quality should be \u2264104E. coli per 100\u00a0ml when children under 15 are exposed. With the model scenario of lettuce consumption for unrestricted irrigation, the use of wastewaters containing \u2264104E. coli per 100\u00a0ml results in a rotavirus infection risk of ~10-2 pppy; however, again based on epidemiological evidence from Mexico, the current WHO guideline level of \u22641,000 E. coli per 100\u00a0ml should be retained for root crops eaten raw.<\/jats:p>","DOI":"10.2166\/wh.2006.055","type":"journal-article","created":{"date-parts":[[2006,10,11]],"date-time":"2006-10-11T14:40:25Z","timestamp":1160577625000},"page":"39-50","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":147,"title":["Health risks in wastewater irrigation: Comparing estimates from quantitative microbial risk analyses and epidemiological studies"],"prefix":"10.2166","volume":"5","author":[{"given":"D.
