Microbiological Qualities of Some Street Drinks Sold in the Street Near at Daffodil International University a Project Report

Abstract

Street Drinks plays an important role in common people’s life. The quick accessibility of these street beverages makes them one of the most popular beverage choices for city dwellers. Due to the ingestion of tainted non-homemade food over the years, numerous cases of water-borne infections have been observed. This investigation was done to evaluate the microbiological safety of drinks being sold on the street. This study looked at the microbiological quality of the four most popular drink items sold by street vendors in the Dattapara neighborhood of Daffodil International University, Dhaka, Bangladesh. The presence of pathogens that cause urinary tract infections, such as Shigella spp. And Salmonella spp., as well as total viable count (TVC), coliform and staphylococci count (SC), fungal count (FC), and other variables were noted in this study. This study emphasizes the amount of microbial loads present in lemon, papaya, apple & alovera juice. This study shows average of total viable count & coliform by using Nutrient agar medium & Mac conkey agar medium. In this project it has shown the total viable count of lemon juice is (3.2×105), papaya juice (3.4×105), orange juice (6.76×104), Aloevera juice (2.2×103) by using Nutrient agar medium & by using Plate count agar medium the total viable count lemon juice is (6.2×105), papaya juice is (5.32×105), Orange juice (5.76×106), Alovera juice (4.2×103). Similarly Mac conkey agar medium has found out the count of coliform on the samples lemon juice (1.3×106), papaya juice (1.5×105), Orange juice (1.3×104), Aloevera juice (0.87×106). This study shows those microbial levels are more than safety level. As a result These juices are not safe for consuming. The report also suggests that the government and food producers work together to implement some preventive measures and uphold the generally accepted hygienic practices for handling, preparing, and cooking food. To preserve a hygienic environment and prevent the spread of dangerous pathogens through consumption of tainted foods, it is imperative that such procedures, laws, and regulations regarding street drink vendors be put into effect.
