CURRENTLY, DEMAND FOR NATURALLY GROWN FOOD IS INCREASING SIGNIFICANTLY, AND FARMERSARE TRYING TOMEETTHE REQUIREMENTS OF ORGANIC SYSTEM WHICH IS A BIT COMPLEX. COMPLEXITIES OF ORGANIC FARMING, INCLUDING SOIL FERTILITY, SOIL MICROBIAL DIVERSITY, AND USE OF ANIMAL MANURES, ARE REQUIRED TO MANAGE ON PASTURE/ORGANIC FARMS. INTEGRATED CROP-LIVESTOCK FARMS (ICLFS), IN WHICH FARMERS GROW BOTH CROP AND LIVESTOCK, IS A TYPICAL EXAMPLE. MICROBIAL ECOLOGY OF ICLFS IMPACTS THEIR PRODUCT SAFETY THROUGH PATHOGEN TRANSFER BETWEEN ANIMALS AND CROPS. RECENT REPORTS OF PATHOGEN-CONTAMINATED PRODUCTS SOLD IN ON-FARM/FARMERS MARKETS HIGHLIGHT THE NEED FOR ASSESSMENT OF THE ECOLOGICAL PATTERNS OF FOODBORNE PATHOGENS IN ICLFS AND THEIR TRANSFER ROUTES TO CROPS. PATHOGENS ARE COMMONLY TRANSMITTED BETWEEN LIVESTOCK AND CROPS DURING SOIL AMENDMENTS WITH COMPOSTED ANIMAL WASTE, OR BY WORKERS, EQUIPMENT, AND VECTORS. IN THIS STUDY, WE AIM TO ASSESS THE ECOLOGICAL DYNAMICS OF TWO MAJOR BACTERIAL PATHOGENS,LISTERIA MONOCYTOGENES(LM) ANDCAMPYLOBACTER JEJUNI(CJ), PARTICULARLY THEIR SURVIVAL AND SPREADING ABILITY, AND BLOCK THEIR CROSS-CONTAMINATION PATHWAYS BY IMPROVING FARM PRACTICES AND POST-HARVEST PROCESSING
