These changes occur in cut tomatoes kept in the open as the nutrients present in cut tomatoes provide a suitable medium for the growth of a pathogenic microorganism, especially Salmonella.
The pH and water activity of tomatoes are favourable for the growth of these pathogens.
Once these get attached to the surface of a cut tomato, they start secreting polysaccharide fibres resulting in the formation of biofilm, which enhances their ability to survive even under unfavourable environmental conditions.
