Ascariasis effects approximately one quarter of the world’s population and is particularly prevalent in developing countries. As improvements in sanitation in most of these countries becomes more widespread, composting of human excreta and sewage sludge has become a popular and cost effective method for the disposal of these products, as well as offering a valuable source of organic fertiliser. If, however, the composting process is not properly controlled there may be a potential risk from pathogen and helminth infection to workers handling the compost and consumers of foodstuffs grown on land treated by the compost. |
