Food and Water Safety

Framework for Conducting a Risk Analysis for Peri-Urban Wastewater Use

The objective of this research is to understand the dynamic relationship between wastewater used for irrigation and food safety in terms of a) production and processing of food with wastewater; b) inputs to food production such as fertilizers and pesticides, and soil; and c) consumption of food produced using wastewater for irrigation, which will have adverse effect on health and nutrition.

The specific objectives are:

  • to understand the demand for safe food in urban and peri-urban areas where wastewater is used uncontrollably for irrigating agricultural crops;
  • to estimate the consumers’ willingness to pay a price premium for ensuring good quality and safe food and water;
  • to use a risk assessment to demonstrate the base line risk associated with using wastewater for food production;
  • to identify cost-effective control measures for reducing risks associated with use of wastewater for irrigation; and
  • to communicate these findings to consumers and decision makers
