Interpretive Summary: Outbreaks of foodborne illnesses caused by pathogenic bacteria have typically involved meats and processed foods. Increasingly such problems are being linked to fresh produce. One of the suspected reservoirs for pathogens that contaminate produce in the field are concentrated animal operations generating manure that can carry pathogens. This paper describes our efforts to develop improved detection methods for pathogens, particularly for Mycobacterium avium ssp. paratuberculosis. We also report on our efforts to understand how manure management systems affect the chemical environment on dairies. Our long-term goals are to develop integrated manure management systems that reduce pathogen numbers on dairies, thereby reducing chances for food contamination in the field.
