| Abstract | Components of municipal solid waste (MSW) entering landfills may contain a variety of pathogenic bacteria, viruses, and parasites. Pathogens of concern usually originate from humans or animals who are infected and they can occur on the skin, saliva, urine, and feces. The major concern is with enteric pathogens because of their potential for long-term survival in the environment. Enteric pathogens are transmitted by the fecal-oral route and may be transmitted by either contact with fecally contaminated material or ingestion of contaminated food or water. Enteric pathogens may be present in food wastes, disposable diapers, pet wastes, sewage sludge, and septic tank wastes. Information on the actual concentrations and fate of pathogens in MSW is limited. Most of the research on this topic was conducted in the 1970s in an attempt to determine the potential for groundwater contamination by enteric viruses. Unfortunately, many new groups of pathogens have been discovered which may exhibit greater survival in the environment or potentially could grow in MSW. Although, overall, the risk from pathogens in solid waste appears to be minimal if it is properly handled and disposed, pathogens always should be reevaluated as new information becomes available. Table 1 summarizes the major human enteric pathogens of concern, including protozoa, bacteria, and viruses. In this chapter, information on the sources and concentration of these enteric pathogens is provided, as well as their fate and survival in landfills, landfill leachate, and compost.
