ABSTRACT This study performed microbial analysis of nutrient film technique (NFT) hydroponic systems at three indoor farms in Singapore. To justify the necessity to sanitize systems, strong biofilm-forming bacteria were isolated from facility and investigated with their influence on Salmonella colonizing polyvinyl chloride (PVC) coupons solutions. Last, sanitization solutions evaluated both laboratory-scale field-scale tests. As a result, microbiome composition NFT was found be highly...
We investigated the fate of Salmonella in lettuce seeds grown a hydroponic system and potentials applying photodynamic inactivation (PDI) to enhance microbial safety farming systems.
Abstract BACKGROUND Singapore’s status as a first world island city-state which relies chiefly on food imports to meet the demand for consumption presents unique challenges in terms of microbial safety and quality. Despite efforts Ministry Health Singapore, conjunction with Agri-Food & Veterinary Authority Singapore National Environment Agency actively collaborate together promote foodborne diseases are still major public health issue. OBJECTIVE The aim review was summarize various...
Salmonella enterica subspecies serovar Saintpaul (S. Saintpaul) is an important gut pathogen which causes salmonellosis worldwide. Although intestinal usually self-limiting, it can be life-threatening in children, the elderlies and immunocompromised patients. Appropriate antibiotic treatment therefore required for these However, efficacy of many antibiotics on S. infections has been greatly compromised due to spreading multidrug resistance (MDR) plasmids, poses serious threats public health...
Although conventionally considered an animal pathogen, recent evidence increasingly suggests that fresh produce may act as significant transmission vehicles and alternative hosts to Salmonella . This study reports the differential survivability of two genetically similar Thompson strains (ST 889B ST 688C) on adaxial surface pre-harvest basil ( Ocimum basilicum ) leaves. Upon inoculation, distinct phenomena, a dried water-print or macroscopic lesion, were observed within 24 h. survived better...
ABSTRACT This study performed microbial analysis of nutrient film technique (NFT) hydroponic systems on three indoor farms in Singapore (the “what”). To justify the necessity sanitizing systems, strong biofilm-forming bacteria were isolated from facility and investigated for their influence Salmonella colonization polyvinyl chloride (PVC) coupons solutions “why”). Finally, sanitization evaluated with both laboratory-scale field-scale tests “how”). As a result, microbiome composition NFT was...
This study aims to investigate the in vitro pathogenicity of Chromobacterium haemolyticum strain WI5 toward intestinal tract, its resistance water treatments, and potential for foodborne transmission through leafy greens produced hydroponic systems.
Singapore’s status as a first world island city-state which relies chiefly on food imports to meet the demand for consumption presents unique challenges in terms of microbial safety and quality.

The aim review was summarize various reported past few years well give an...
Aims Although a link between agricultural cephalosporin use and resistance in Salmonella has been demonstrated with the drug ceftiofur, underlying mechanism of correlation is unclear. This study investigated impact ceftiofur exposure S. Saintpaul on ceftriaxone resistance, gene expression conjugative transfer blaCTX-M-65 gene. Methods Results Prior caused twofold increase MIC from 1024 to 2048 µg ml−1 towards increased enzymatic activity BlaCTX-M-65 2·2 folds 3·46 7·67 nmol nitrocefin...
