Description:
The health risks pathogens pose to water and food resources are highly dependent on their fate and transport in agricultural settings. In order to assess these risks, and understanding of the factors that influence pathogen fate in agricultural settings is needed and is critical in developing control/adaptation strategies to minimize pathogen transfer. It is interesting to note that a significant fraction of studies investigating the fate of pathogens in manure report an initial growth phase of the bacterium in question before the start of a decline phase. However, few to no studies have investigated solely the re-growth of these pathogens in these matrices. The photodegradation of dissolved organic matter (DOM) results in the release of a variety of photo-products that stimulate the growth and activity of microorganisms in aquatic environments, thus it is reasonable to hypothesize that cow manure exposure to sunlight can result in the re-growth of pathogens in the environment.
