Fruits and vegetables form an important part of a healthy diet. This is especially true as nutritionists recommend natural unprocessed food asthe ultimate source of all the goodfibers. However, due to the use of manure and the use of wastewater for irrigation, most leafy productssuch ascarrots, reddish, cabbage, and leafy vegetables have a high load of pathogenic bacteria. This makes the consumption of suchunprocessed food a health concern. Common chemicals used to clear the surface microflora from fresh produce include the use of chlorine and hydrogen peroxide. The presence of these chemicals in trace amounts has harmful effects on health.Fruits of Garcinia indicais considered as generally recognized as safe (GRAS) food and are rich in hydroxy citric acid besides many other phytochemicals. Antioxidant activity of the fruit is widely reported. A 10% aqueous extract of Garcinia indica was prepared. The extract was completely dried before use. Carrot and lettuce samples were dipped in this solution for 5, 10 and 15 minutes. After the treatment the samples were washed and the wash water was collected for enumeration of bacteria. The control sample of carrot had 10 5 cfu/mL bacterial load whereas the lettuce samples had a mean bacterial count of 10 4 cfu/mL. After the treatment of the samples with the extract for 15 min, the wash water used for lettuce showed 3 log reduction in bacterial count whereas one log reduction was observed in carrot.
