Recently there has been a lot of attention focused on producing
medicines and products that are natural. Several
fruits and fruit extracts, as well as arrowroot tea extract [1]
and caffeine [2], have been found to exhibit antimicrobial
activity against E. coli O157:H7. This suggests that plants
which manifest relatively high levels of antimicrobial action
may be sources of compounds that can be used to inhibit
the growth of foodborne pathogens. Bacterial cells could be
killed by the rupture of cell walls and membranes and by the
irregular disruption of the intracellular matrix when treated
with plant extracts
