N2 - Organic fertilizers use has been recently questioned because of the potential for Salmonella regrowth if animal manure is used as the starting organic waste. The aim of this study was to determine the potential for Salmonella enteric subsp. entérica regrowth in a vermicompost and compare it to a Class A biosolids, soil, and amended soil. Different initial Salmonella inocula were added to the mixtures with 30% moisture content and incubated for 20 days. Salmonella first declined to undetectable levels in the biosolids, followed by vermicompost, and persisted the longest in soil and amended soil. No Salmonella regrowth was observed in any of the treatments tested.
