“…But the final product which they drink are often contaminated with various pathogens. The vendors don't have the proper knowledge about the transmission of microorganisms from their simple actions (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37). For example, the hygienic condition of the vendor himself is one critical factor.…”

Microbiological quality assessment for drug resistant pathogenic microorganisms from the fresh vended fruit juices

Fruit juices are very popular due to their freshness and taste. These juices contain all the nutritive values those were present in whole fruits. Fresh juices are healthful drink for people of all ages. But the condition is quite opposite if they become contaminated with pathogenic bacteria during the juice processing. Because of the nutritive properties juice can give enough opportunities to the microorganisms to survive and multiply. In our current study we included eight types of fresh juices to study the microbial load. All the samples were heavily contaminated. Total bacterial and fungal count was found to be up to 3.0×10 7 cfu/ml and 2.6×10 6 cfu/ml, respectively. Salmonella spp. and Shigella spp. was present only in one sample. Staphylococcus aureus and Pseudomonas spp. were the most prominent in all of the eight samples. Vibrio spp. was found in six samples ranging from 2.0×10 2 cfu/ml to 2.9×10 4 cfu/ml. All the pathogenic isolates showed drug resistance towards the most commonly prescribed antibiotics indicating the risk of difficulty in eradicating diseases.

“…In the field of food microbiology sector in Bangladesh, while lots of works regarding food safety and security issues have been addressed; the specific endogenous oxidative stress ( identification strategy of microbial contaminants in the milk and milk products is still in its infancy (1,8,14,26,(33)(34)(35)(36). Nevertheless, a few earlier researches reported that microbial contamination in milk and milk products could take place from three principal sources: inside the udder; the exterior of the udder and the surface of milk handling; and storage equipment (15,37).…”

“…Contamination of milk and milk products by pathogenic microorganisms is a global health concern; however, its fatal impact on human and animal health in the developing countries including in Bangladesh has not yet been extensively resolved except a few research works (1,14). Since the constituents of milk and milk based products are adequate enough to support the microbial growth and replication, the dairy foods intensely demand a careful microbiological examination for the quality assurance for the sake of consumer safety.…”

“…Since the constituents of milk and milk based products are adequate enough to support the microbial growth and replication, the dairy foods intensely demand a careful microbiological examination for the quality assurance for the sake of consumer safety. Some of the previous local researches within Dhaka city, Bangladesh revealed that raw or un-pasteurized milk and milk products could be very efficient vehicle for bringing a large number of people into contact with potential microbial hazards with an ultimate effect in the onset of various diseases (1,14,15). Therefore, the safety of milk products in context to the onset of food borne diseases stands as a major global health issue, especially in the developing countries where production of milk and milk product usually takes place a under poor hygienic practices (14,15).…”

Isolation and quantification of microorganisms from some common milk products within Dhaka city, Bangladesh

While milk is well known to be a balanced diet with its high nutritional values, conversely milk and milk products may serve as potential substrate for the growth and proliferation of a range of microorganisms which in turn fatally influences mass public health. Current study attempted to examine the likelihood of microbial contamination within some common milk products consumed by the locality of the city of Dhaka, Bangladesh. All samples exhibited the presence of bacterial and fungal contamination within a range of 10 2 -10 4 cfu/mL and 10 2 -10 3 cfu/mL, respectively. Among specific pathogens, Staphylococcus spp. was noticed to be the predominant ones and was recovered from 9 samples out of 20 samples in a range of 10 2 -10 3 cfu/mL. Klebsiella spp. and Vibrio spp. were found within 6 and 9 samples, respectively. Products were also found to be contaminated with Vibrio spp. Study of antibiotic susceptibility test revealed that all the pathogenic bacteria were resistant against most of the commonly used antibiotics of which several isolates showed multi-drug resistant (MDR) trait. Therefore, the presence of pathogenic bacteria with the drug-resistance property in tested milk and milk products overall imparted the necessity of maintaining standardized hygienic handling and processing means for better management of public health.

Purpose – The purpose of this review is to narrate the microbiological quality of variety of street foods which are largely consumed by the Bangladeshi people of all ages. However, these foods are prone to microbial contamination. Most of the vendors lack the awareness on hygiene during preparing, processing or handling the foods. The insufficiency in regular microbiological analysis further casts the possibility of disease onset. The need of microbial analyses of these foods also remains unclear to the consumers, which, in turn, results in microbial infections and intoxications remaining unnoticed. Design/methodology/approach – The present review focused on the microbiological quality of the street foods projected from the locally conducted researches on street foods, and pondered on the possible management from a microbiological perspective for ensuring consumer safety. Findings – This paper provides comprehensive information on the microbiological quality of street foods, requirement of maintenance of hygiene by the vendors and consumers and the necessity of adopting proper management during food preparation. Originality/value – Demonstration of microbial prevalence in the street foods may bring imperative information on food safety and security. The conclusive message of this review is about the general consciousness on the microbiological aspects of street food contamination.
