“…The present study was conducted involving epidemiological surveillance of seven fresh vegetables generally consumed as raw due to their higher nutraceutical properties. Evaluation of the microbiological quality of seven fresh vegetables being grown along the Buddha Nallah, Salmonella enterica count in range of 4.32 to 5.09 log cfu g-1 and Bacillus cereus count from 2.69 to 4.35 log cfu g-1 was recorded in samples of carrot, radish, cucumber, tomato, cabbage, spinach and long melon [12,13]. Many other human pathogens were also found including E. coli, A. hydrophila, S. flexneri, L. monocytogenes, Y. enterocolitica, C. jejuni, V. cholera, K. pneumonia and S. aureus were also detected on fresh vegetables.…”

“…So, constant efforts were made to evaluate the persistence of pathogens on the basis of virulence factors and antibiogram profiling involving the clustering analysis for diversity study. Certain epidemiological studies have illustrated the Multi Drug Resistant (MDR) Salmonella enterica and Bacillus cereus predominately present in fresh produce [12][13][14][15] (Annexure I, II). Resistance to antibiotics like ampicillin, Cloxacillin, Tetracycline, chloramphenicol and trimethoprim-sulfamethoxazole [12,13,15] against salmonella strains has been cited which can reflect the seriousness of the drug resistance issues.…”

The mobility of these pathogens from field to fork and their virulence expression in mammalian cells can detrimentally effect the public health and safety.…”

People are being more comprehensive to the nutritional benefits of raw vegetables and have changed their eating habits. Undoubtedly, fresh vegetables are rich in nutrients, vitamins and minerals essential for health but with a downside of both epiphytic non-pathogenic and pathogenic bacteria like Salmonella enterica and Bacillus cereus causing illness. Soils irrigated with sewage water for raising crops and a soil nearby sewage disposal sites possesses the potential pathogenic load. The faecal index of such sewage water used for agriculture was above the maximum permissible limit of 100 MPN/ml (Recommended by Indian Environment Ministry). These food pathogens are predominately found on vegetables sourced from those regions and were characterized as highly virulent due to presence of disease causing genes in them. They have high multiple drug resistance index which pose a grave threat to public health. There is need to monitor the quality of irrigation water for public health safety. Further, the vending operations should be critically controlled to decrease the risk of contamination by improper storage and handling of the vegetables.
