chickenFollowing 144 h storage at 3◦C, Log CFU/g of E. coli was decreasedfrom 4.55 to 4.09, 3.98, 3.47 and 3.34 in the control, chitosan,oregano and chitosan + oregano groups, respectively. In contrastto chitosan, the survival of bacterium was inhibited by oreganoEO (P < 0.05). Furthermore, the inhibitory effect of oregano wasnot enhanced by chitosan (P > 0.05). The same results were alsodemonstrated in the samples stored at 8◦C and 20◦C (Table 1).
