The efficacy of “gaseous” ozone in reducing numbers and re-growth of food-borne pathogens, (<i>Escherichia coli </i>and<i> Listeria </i>spp.), on leafy salads was investigated using spinach. A preliminary<i> in vivo</i> study showed 1-log reduction in six strains of <i>E. coli</i> and two species of <i>Listeria</i> spp. on...

Excessive salt rate can adversely influence the physical, chemical, and biological properties of soils, mainly in arid and semi-arid world regions. Therefore, salt-affected soils must be reclaimed to maintain satisfactory fertility levels for increasing food production. Different approaches have...
