Abstract
This objective of this study was to investigate inhibitory effect of natural antimicrobials on Listeria monocytogenes isolated from Korean slaughterhouses. A mixture of 15 strains of L. monocytogenes at low (3 Log CFU/mL)and high (7 Log CFU/mL) concentration was exposed to various extracts (grapefruit seed extract, citrus fruits extract, ginger extract, pear extract, Japanese apricot concentrate, balloon flower extract, jujube extract, and omija extract) at 0.001-4.0μg/mL . Ginger extract, pear extract, Japanese apricot concentrate, balloon flower extract, jujube extract, and omija extract showed no antimicrobial effects to high-concentration of L. monocytogenes (7 Log CFU/mL). However, grapefruit seed extract and citrus fruit extract showed antibacterial effects against L. monocytogenes at 3 and 7 Log CFU/mL with MBCs of 0.001 and 0.002 μg/mL, respectively. These results indicate that grapefruit seed extract and citrus fruits extract can be used to control L. monocytogenes as natural antimicrobials.
