The aim of this study was to investigate antibacterial effects of oregano and thyme essential oils (EOs) on some food-borne
bacteria. GC-MS analysis of EOs was performed in order to determine their composition and phenols were predominant
constituents. The investigation of the antibacterial effects of EOs was performed on Salmonella Enteritidis, Salmonella
Thyphimurium, Staphylococcus aureus, methicillin resistant Staphylococcus aureus, Escherichia coli and Bacillus cereus, and
MICs were determined by broth microdilution method. EOs exhibited antibacterial activity against all tested microorganisms.
