Sensitivity of food pathogens to garlic (Allium sativum)

摘要

The inhibitory activity of garlic (Allium sativum) against Staphylococcus aureus, Salmonella typhi, Escherichia coli and Listeria monocytogenes was measured by the 'turbidity' method. Minimum inhibitory concentration (MIG) of garlic at 80% inhibition level was calculated for these bacteria. All bacterial pathogenic strains tested were inhibited by garlic; E. coli was most sensitive and Listeria monocytogenes was least sensitive. Therefore, garlic has potential for the preservation of processed foods.
