Abstract Introduction: Listeria monocytogenes is an opportunistic foodborne pathogen that can cause death to infected humans. The bacterial was frequently associated with food-borne origins including seafood. Thus, the present study aimed at screening anti-listeria-producing lactic acid bacteria (AL-LAB) isolated from intestinal tracts of wild gilt-head seabream ( Sparus aurata ). Materials and Methods: Lactic (LAB) were 15 seabreams screened for antimicrobial activity against . LAB...

This study has improved the sanitation of head-on gutted (HOG) Atlantic salmon (Salmo salar) by using neutral electrolyzed oxidizing water (NEW) ice. NEW and ice (NEI) were tested on Listeria monocytogenes Pseudomonas aeruginosa-contaminated fillet skin. Treatment storage with melting NEI reduced P. aeruginosa 1.1 2.4 log CFU/cm2, respectively. Storage 100 ppm suppressed L. 1 CFU/cm2. In industry, HOG a concentration could therefore be used for pre-treatment to reduce microbial contamination...
