TLDR
Microbial quality of common salad vegetables collected from Dhaka metropolis was analysed to detect the presence of bacterial pathogens and occurrence of viable but non-culturable (VBNC) bacteria was noticed.Abstract:
Microbial quality of common salad vegetables (viz. carrot, cucumber, tomato and lettuce) collected from Dhaka metropolis was analysed to detect the presence of bacterial pathogens. The occurrence of huge numbers of fecal coliforms (1.0×10 4 - 4.09×10 6 cfu/g), Escherichia coli (1.0×10 4 - 5.0×10 8 cfu/g), Staphylococcus aureus (2.0×10 5 - 5.95×10 7 cfu/g), and Listeria spp. (1.5×10 6 - 6.5×10 7 cfu/g) were detected in all the tested samples. Interestingly, occurrence of viable but non-culturable (VBNC) bacteria was also noticed.read more

Food safety issues in fresh produce supply chain with particular reference to sub-Saharan Africa
TL;DR: In this article, the authors highlight the importance of small, resource-poor farmers in agricultural production in sub-Saharan Africa and advocate capacity building in food safety and the application of good agricultural practices and good hygienic practices.
Microbiological analysis of liquid oral drugs available in bangladesh
TL;DR: Existence of microorganisms in the oral liquid samples might explain the treatment complicacy of the diseased children and a routine microbiological study of such drugs is suggested.

The Viable but Nonculturable State in Bacteria
TL;DR: The ability of cells to resuscitate from the VBNC state and return to an actively metabolizing and culturable form is described, as well as the ability of these cells to retain virulence.

Ecological factors influencing survival and growth of human pathogens on raw fruits and vegetables.
TL;DR: Outbreaks of human infections associated with consumption of raw fruits and vegetables have occurred with increased frequency during the past decade and a general lack of efficacy of sanitizers in removing or killing pathogens has been attributed, in part, to their inaccessibility to locations within structures and tissues that may harbor pathogens.
