| dc.description.abstract | Fresh produce may be contaminated by bacterial pathogens, including <i>Listeria monocytogenes,</i> during harvesting, packaging, or transporting. A low-intensity cavitation process with air being injected into water was studied to determine the microbubbles’ efficiency when detaching <i>L. monocytogenes</i> from stainless steel and the surface of fresh cucumber and avocado. Stainless steel coupons (1″ × 2″), cucumber, and avocado surfaces were inoculated with <i>L. monocytogenes</i> (LCDC strain). After 1, 24 or 48 h, loosely attached cells were washed off, and inoculated areas were targeted by microbubbles (~0.1–0.5 mm dia.) through a bubble diffuser (1.0 L air/min) for 1, 2, 5, or 10 min. For steel, <i>L. monocytogenes</i> (48 h drying) detachment peaked at 2.95 mean log reduction after 10 min of microbubbles when compared to a no-bubble treatment. After 48 h pathogen drying, cucumbers treated for 10 min showed a 1.78 mean log reduction of <i>L. monocytogenes</i>. For avocados, <i>L. monocytogenes</i> (24 h drying) detachment peaked at 1.65 log reduction after 10 min of microbubbles. Microbubble applications may be an effective, economical, and environmentally friendly way to remove <i>L. monocytogenes,</i> and possibly other bacterial pathogens, from food contact surfaces and the surfaces of whole, intact fresh produce. | en |
