A year long search for pathogens in sludge products that could be distributed and marketed (D and M) to the general public was completed recently for the U.S. Environmental Protection Agency by the County Sanitation Districts of Los Angeles County. The study analyzed 498 samples of sludge products that were taken serially from 26 locations in 17 states over a period of one year. Each sample was analyzed for over 15 pathogen and indicator microorganism groups. The study found that the sludge products were remarkably free of pathogenic viruses and viable parasitic ova.
