Summary

Introduction

Food-borne disease is an increasingly major public health problem all over the world (Newell et al, 2010). Purkait et al.: Antibacterial and Antioxidant Potential of Spices life of food items but they have accumulated evidence that they could be toxic and carcinogenic. Another great concern is the emergence of antimicrobial resistance in food-borne pathogens (Mathew et al, 2007). Methods: In vitro antibacterial efficacy of black cumin, black pepper, cinnamon, clove, and nutmeg EOs were evaluated against some food-borne bacteria using agar well diffusion, microbroth dilution, and time-kill assay methods. Conclusion: The results provide evidence that EOs of clove, black pepper, and cinnamon may serve as effective natural preservatives in the food industry. Further studies are needed for their plausible applications in the food industry
