Abstract:

Fruits and vegetables are the main dietary source of nutrients, micronutrients, vitamins and fiber for human, which are consumed widely. However, they are contaminated with diverse range of bacterias and their spores through reproductive cells. Fruits and vegans samples were collected from four different places viz. Bhalout (Rohtak, India), Chandpur (Jind, India), Chang (Bhiwani) and Ganaur (Sonipat). Test samples were processed to identify total viable cells (cfu/ml). The highest total viable count was found in tomato followed by lemon. Bacillus, Micrococcus, Staphylococcus, Klebsiella, Escherichia coli, Pseudomonas and Enterobacter species were isolated and identified on the basis of morphology (Gram staining and cell morphology), biochemical tests (indole production test, methyl-red test, Voges-Proskauer test and citrate utilization test) and growth on selective cum differential culture media (such as MacConkey agar and mannitol salt agar media). It was found that Bacillus, Klebsiella, E. coli, E. aerogenes and Pseudomonas were dominating species in the spoilage of every category of fruits and vegan samples. The bacteria particularly Gram negative, was key responsible for food spoilage. Proper handling of fruits and vegetables, hygiene transportation and appropriate storage is necessary to avoid microbial food spoilage and related health risks.
