Background: Being led by the previous observation of bacterial growth and survival in the fresh-cut tomato, carrot, lettuce and cucumber, current investigation further attempted to emphasize on the growth and consequent endurance of the pathogenic bacteria within chili (Capsicum frutescens), onion (Allium cepa), capsicum (Capsicum annuum) and coriander (Coriander sativum) collected from local markets.

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.

Present study assessed the microbiological quality of different categories of consumable potatoes collected from Bangladesh Agricultural Research Institute (BARI), the largest multi-crop research institute of the country conducting research on a large number of crops. Five samples each from 15 categories of potato samples (Lara, Quincy, Cardinal, Esprit, Meridian, Lady Rossetta, Astrix, Soikat, Red potato, White potato, Russet potato, Yellow flesh potato, Sweet potato, Purple potato and Petiets potato) were subjected to microbiological analysis through conventional culture followed by the biochemical identification tests of the pathogens. A huge array of bacterial and fungal contamination was noticed within a range of (~108 cfu/g) in almost all samples studied. Among the bacterial pathogens, Escherichia coli and Staphylococcus spp. were found to be predominant. Study of antibiogram revealed that most of the isolates were resistant against the commonly used one or multiple antibiotics. Finally, all the samples were also examined for presence of any anti-microbial activity against different pathogenic bacterial species. Astrix potato samples exhibited antimicrobial activity against Shigella spp and the Russet potato samples exhibited the anti-bacterial activity against Staphylococcus spp. DOI: http://dx.doi.org/10.3329/sjm.v3i1.22747 Stamford Journal of Microbiology, Vol.3(1) 2013: 21-25
