	abstract = {The goal of this study was to determine effects of temperature and soil type on survival of Ascaris ova in two biosolid-amended, desert soils. Results of this study suggest that a waiting period of 120 days at average soil temperatures of 25�C or 90 days at 37�C after land application of biosolids on fields to which lettuce is planted would result in annual risks of less than 1:10,000 for Ascaris from consumption of lettuce with an ova concentration of 4 ova g dry solids.},
