Microbiological contamination of ready-to-eat vegetable salads in developing countries and potential solutions in the supply chain to control microbial pathogens

The consumption of ready to eat vegetable salads among consumers in developing countries has increased with the change in life style pattern. However, food borne disease linked to these salads poses safety threats. Studies have shown the occurrence of various microbial pathogens which includes Escherichia coli, Listeria monocytogenes, coliforms, Salmonella etc. in these types of ready to eat vegetable salads. In order to overcome these safety threats, to control the microbial pathogens and to enhance the shelf life, different techniques like modified atmospheric conditions, refrigeration, innovative technologies etc. are exploited. This review insight on pathogenic prevalence of ready to eat vegetable salads in developing countries and technological advances used to counter these pathogens.
