Sewage Sludge in Organic Production

Dear Sanet

The Northeast Organic Farming Association of New Jersey lists sewage sludge
as a prohibited substance.  Are there certifying agencies which permit it? 

I am pointing this out because the previous message "Federal
Sludge-Labelling Bill", mentioned that  " "organic" crops can be grown on
field where  sludge from major cities has been dumped".
