AB  - Due to the phaseout of methyl bromide (MeBr), there is a need for broad-spectrum 
      soil fumigation alternatives for pest management. Little is known about the 
      impact of fumigation alternatives on foodborne pathogens, such as Salmonella, in 
      agricultural soils. This study investigated the effect of MeBr alternative 
      fumigants on Salmonella reduction in soil. Sandy loam soil was collected from a 
      conventional farmed vegetable field and inoculated with either Salmonella Newport 
      J1892 or Typhimurium ATCC 14028 (5.9 +/- 0.3 log(10) colony-forming unit [CFU]/g). 
      Each of the four fumigants labeled for pest management (1,3-dichloropropene, 
      chloropicrin, dimethyl disulfide, and metam sodium) was applied at labeled 
      maximum application field levels to soil in pots and stored for a 2-week period. 
      Sterile water was used as a control. Following the 2-week period, Salmonella 
      concentrations in soil samples were enumerated at 1, 7, 14, and 21 days 
      postfumigation. The mean concentration of Salmonella Newport was significantly 
      higher than that of Salmonella Typhimurium 1 day after fumigation (p = 0.015). 
      Fumigation using 1,3-dichloropropene or dimethyl disulfide significantly reduced 
      Salmonella Newport and Salmonella Typhimurium concentrations, compared with the 
      sterile water control. The rate of Salmonella reduction in soil treated with 
      dimethyl disulfide was higher (0.17 +/- 0.02 log(10) CFU/g/day), compared with soil 
      treated with the other fumigants (0.10-0.12 log(10) CFU/g/day). Due to the 
      reduction of Salmonella, alternative fumigation treatments may mitigate potential 
      Salmonella contamination in soil within farm environments.
