Poultry litter is a good source of nutrients and organic matter for growing crops (Marsh et al., 2009). Poultry Manure is made up of faecal droppings, wood shaving (bedding), waste feed and high load of microbes (2 - 4). It is commonly used by vegetable farmers as organic fertilizer (1 - 3). Vegetable contamination by pathogenic microbes is of great health importance in leafy vegetables, especially those consumed raw, as farmers often broadcast their poultry manure over already established crops (2, 3). Human exposure to poultry dust has been associated with various infectious, allergic, respiratory and immunologic diseases (4).
