**8. Conclusion**

Prevalence of *Salmonella* infection has increased markedly in both humans and domestic animals. Probably as a consequence of the extensive use of antibiotics surveillance networks have indicated that the incidence of human *Salmonella* food poisoning caused by antimicrobial resistant *Salmonella* is rising in many countries. In present, the anti-*Salmonella* spp. properties of plant extract/essential oils from a variety of plant have been assessed. It is clear from these studies that these secondary plant metabolites have potential as alternative antibacterial in food conservation. The phenolic compounds are most active and appear to act principally as membrane permeabilisers. In addition, consumers are also demand for food preservation from natural source. Therefore, the incorporating plant extracts in or onto food packaging materials to against foodborne pathogen, especially *Salmonella* spp., is of increasing interest.
