Characteristic colonies from above were sub-cultured on nutrient agar and Eosin Methylene Blue (EMB) agar (Oxoid, UK), incubated at 37°C for 24 hours, and subjected to Gram's staining and biochemical tests for confirmation. Salmonella swarms through the medium from the inoculation site and the H-antigen is detected by using material from the motility zone. Salmonella ChromoSelect Agar is a selective medium used for simultaneous detection of Escherichia coli and Salmonella from food and water. Samples were propagated in nutrient broth and nutrient agar media followed by culture on selective media– Eosin Methylene Blue Agar, MacConley agae, Brilliant Green Agar, Salmonella -Shigella Agar.
