Statement on the use of untreated manure containing raw sewage. Opinion of the Panel on Biological Hazards of the Norwegian Scientific Committee for Food Safety

Abstract

The Norwegian department of agriculture decided to re-evaluate the Regulation No. 951 of 4 July 2003 on fertilizers and soil improvers of organic origin. The Norwegian Food Safety Authority (NFSA) requested VKM for a statement on the use of manure from farms where grey water and human waste (sewage) is disposed of directly to the farm manure cellar. <br> Consideration was given to differences in risk according to the types of domestic wastewater, the species of animal from which the manure derived, the extent and type of sanitary facilities, the crops to which the amended manure is applied, and the effects of storage on infection risk.
