Microbial Quality Assessment and Efficacy of Low-Cost Disinfectants on Fresh Fruits and Vegetables Collected from Urban Areas of Dhaka, Bangladesh. | LitMetric
This study aimed to examine the total viable bacteria (TVBC); total coliform (TCC); fecal coliform (TFC); pathogenic spp., and total fungi (TF); and the effect of different low-cost disinfectants (sterile water, salt water, blanched, and vinegar) in decontamination of 12 types of fruit and 10 types of vegetables. In fruit samples, the lowest TVBC was enumerated at 3.18 ± 0.27 log CFU/g in Indian gooseberry and the highest at 6.47 ± 0.68 log CFU/g in guava. (2.04 ± 0.53-5.10 ± 0.02 log CFU/g), (1.88 ± 0.03-5.38 ± 0.08 log CFU/g), and total fungi (2.60 ± 0.18-7.50 ± 0.15 log CFU/g) were found in all fruit samples; however, no was detected in fruit samples. Similarly, the lowest TVBC recorded 5.67± 0.49 log CFU/g in cucumber and the highest 7.37 ± 0.06 log CFU/g in yard long bean. The (3.48 ± 0.13-4.81 ± 0.16 log CFU/g), (3.57± 0.21- 4.75 ± 0.23 log CFU/g), TCC (1.85 ± 1.11-56.50 ± 37.14 MPN/g), TFC (1.76 ± 0.87- 3.78 ± 3.76 MPN/g), and TF (3.79 ± 0.18-4.40 ± 0.38 log CFU/g) were recorded in all vegetables samples, but no was detected in yard long bean, pointed gourd, carrot, tomato, cucumber, or brinjal. However, vinegar showed the highest microbial load reduction of selected fruit and vegetables among the different treatments. With vinegar treatment, the highest reduction of TVBC (1.61-log) and TF (2.54-log) was observed for fruits, and TVBC (2.31-log) and TF (2.41-log) for vegetables. All the disinfectant treatments resulted in significant ( < 0.01) bacterial load reduction compared to control for the studied fruits and vegetable samples.
In this study, chitosan (C)-polyvinyl alcohol (P) edible film containing bio-fabricated nanosilver particles (nAg) (as antimicrobial agent) and beetroot peel extract (BRPE) (as antioxidant agent and pH indicator) was used as spoilage indicator in cold-stored rainbow trout fillets. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity (43.02%), reducing power (2.
Nowadays, consumption of fish is becoming a public health concern due to quality and safety issues. This study was designed to assess the proximate composition, microbial quality, and heavy metal accumulation in the Nile tilapia fillet at three selected landing sites in Lake Tana. Fifteen samples were collected and analyzed.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease initially treated with mesalazine (5-ASA). However, its effectiveness is limited by rapid absorption, low colonic concentration, and exacerbation of dysbiosis. Probiotics can mitigate dysbiosis if they survive the acidic conditions of the stomach.

Biological soil amendments of animal origin (BSAAO) are a source of foodborne pathogens that can contaminate fresh produce. This study evaluated the survival of E. coli over 140 d in agricultural soils amended with composted poultry litter (PL), heat-treated poultry pellets (HTPP), or unamended (UN) in Florida (FL) and Georgia (GA).
Biochar has been used to accelerate heating profiles during composting by increasing oxygenation, which could also reduce microbial pathogens. However, the antimicrobial inactivation of foodborne pathogens in compost, by amending with biochar without increased heating profiles, has not been evaluated. In this study, we examined the ability of biochar to inactivate E.
