Abstract
- AIMS We investigated the fate of Salmonella in lettuce seeds grown in a hydroponic system and the potentials of applying photodynamic inactivation (PDI) to enhance microbial safety of hydroponic farming systems. METHODS AND RESULTS Lettuce was grown from Salmonella-contaminated seeds, and rose bengal-mediated PDI was applied. Without intervention, Salmonella could persist in plants and hydroponic farming environment throughout 6 weeks of lettuce growth. Cross-contamination from Salmonella-inoculated to noninoculated seedlings was observed. PDI significantly decreased Salmonella from 3.90 ± 0.31 log colony-forming unit (CFU) per plant to 2.77 ± 0.49 log CFU per plant without extra illumination needed (p
