Garlic (Allium sativum, L.) has a long history of reputed value and actual use for its medicinal, antimicrobial, and pesticidal properties. This study was conducted to find possible developments to natural food preservatives from garlic extracts. Garlic extracts were prepared from fresh crushed garlic and diluted with sterilize distilled water. The sensitivity test was conducted to investigate the antimicrobial effect of garlic extract against six strains of food poisoning bacteria such as Staphylococcus aureus, Escherichea coli, Salmonella typhimurium, Vibrio parahemolyticus, Bacillus subtilis, and Listeria monocytogenes. The results of sensitivity test were then compared with those of Vancomycin and Imipenem which were used as treatment for G. (+) bacteria and G. (-) bacteria, respectively. All of the 6 tested strains exhibited strong or moderate activity. V. parahemolyticus exhibited susceptible only in undiluted solution, but not in diluted garlic extracts.
