AB  - ABSTRACT: Salmonella enterica subsp. enterica serovar Newport is a bacterial 
      foodborne pathogen isolated from several environmental reservoirs on the Delmarva 
      Peninsula and has been associated with several produce-related outbreaks. 
      However, little is known about specific interactions between Salmonella Newport 
      and soil amendments used as fertilizers. The purpose of this study was to 
      determine Salmonella Newport persistence and resuscitation in raw poultry litter 
      (PLR), a common biological soil amendment, and in soils containing poultry 
      litter-based (heat-treated poultry pellets [HTPP]) or chemical fertilizer (urea 
      [U]) amendments to provide equivalent levels of nitrogen to the soil. Inoculated 
      samples were stored in a growth chamber and irrigated regularly over 4 weeks. 
      Soil samples were collected every week for 4 weeks to determine moisture content 
      and surviving Salmonella Newport populations (log CFU per gram dry weight). Data 
      were analyzed by using a one-way analysis of variance and Student's t test. The 
      PLR supported significantly higher (5.07 log CFU/g dry weight [gdw]) populations 
      of Salmonella Newport than HTPP only (1.70 log CFU/gdw). However, PLR-amended 
      (PRLA) soil (2.5 log CFU/gdw) samples had significantly (P < 0.05) lower 
      Salmonella Newport populations compared with HTPP-amended (4.5 log CFU/gdw) and 
      U-amended (4.0 log CFU/gdw) soil samples. The effect of irrigation on Salmonella 
      Newport population levels in PRLA soils was significant, and in a comparative 
      study, the overall increase in the pathogen levels in U-amended soil (mean = 1.12 
      log CFU/gdw) was significantly greater than that in PLRA soil (mean = 0.54 log 
      CFU/gdw), whereas that in HTPP-amended soil (0.80 log CFU/gdw) was not 
      significantly different from PLRA soil.
