Abstract
Organic amendments originating as waste products from animals or humans are associated with an increased food safety risk for fresh-cut produce crops grown in fields when these amendments have been incorporated into the soil.
Such waste products could include domesticated animal manure, human waste/biosolids, waste products from the meat and fish processing industries, treated waste products and green waste that has had contact with animals and their waste products.
A number of different pathogens found in these waste products have the potential to cause human illness.
To understand the risk associated with using these waste products, data is presented on the prevalence and contamination levels of enteric pathogens in human and animal wastes.
Factors identified as contributing to contaminated waste products are then discussed to illustrate measures that could be adopted to mitigate the pathogens presence.
Pathogen survival in the soil amendments as well as in amended soil is also discussed in relation to some of the variables that impact this passive form of treatment.
Various types of active treatments and their efficacy in decreasing pathogen populations are then presented.
