Sommaire de l'article

"Nearly 60% of the sewage sludge in France is recycled in agriculture. Sludge serves as a fertilizer but contains micropollutants. This could modify the consumer's perceived safety concerning the vegetables grown with sludge. In the same way as nutritional value, safety is an attribute of food. Food safety is a public good and in this respect has no explicit price. A consumer is willing to pay for it if he perceives a risk to his health. The purpose of this study is to give a value to food safety relative to the practice of sewage sludge disposal on agricultural soils. Experimental economics is a support to elicit the willingness to pay for safety. Risks linked to one heavy metal (cadmium) have been chosen; they are supposed to be very low and difficult to assess because of the uncertainties involved in the food chain process."
