    1. Human Pathogens in Plant Rhizosphere, Phyllosphere, and Vascular Tissues

    2. Bugs in vegetables Greens, sprouts, vegetables, fruits, nuts were linked to Salmonella and E. coli O157:H7 outbreaks In 1990-2003, 28,315 cases of gastroenteritis were from produce (the second most common vehicle of foodborne illnesses) Early outbreaks were suspected to have resulted from cross-contamination with meats by consumers. Likely not the case Since 1995, 19 E.coli O157:H7 outbreaks from spinach or lettuce, 9 linked to Salinas valley Easy removal from the surface, not from the inner parts Where are the bugs coming from? field/pre-harvest immediately post-harvest warm tomatoes constrict in cool water, suck up bugs thru the stem scar CDC: wash picked vegetables in warm chlorinated water (~200 ppm) dicing + pooling = problem shipment storage (flies, fruit flies transfer bacteria) gamma irradiation

    3. Bugs in vegetables E.coli and Salmonella can persist in manure for weeks-years Bugs from manure colonize veg. surface and persist for up to 2 mo
