This depends on location and is one of the reason a lot of food-grade crops prohibit the application of Municipal sludge. For example, if you are in an area where soil is inherently high in Cadmium (eg. Kildare, Meath), applying sludge can increase the cadmium content of the end product (grain, tubers) to levels beyond the maximum limit set by the European Food Standards Authority. Mind blowing stuff realyAny concerns re heavy metals etc in sludge.
