SOIL DISINFESTATION AND FOOD SAFETY ISSUES

A literature review and some new data are presented on soil disinfestation methods alternative to methyl bromide, their effects on soilborne plant pathogens and human enteric pathogens, as well as the resulting conduciveness or suppressiveness relative to residual or newly introduced pathogens after the disinfestation treatments.
Dimethyl disulphide and 1,3-dichloropropene reduced Salmonella populations slightly, but their effects on inadvertently reintroduced Salmonella populations have not been determined.
Biological soil disinfestation (BSD) is considered the most environmental friendly alternative treatment.
Its direct effect on survival of enteric pathogens has not been determined, but residual pathogen suppression is expected.
Research is needed to determine the direct effects of volatile organic acids produced during BSD treatment on enteric pathogens.
