Infectious diseases due to contaminated street vended food items has happened to an essential concern and public health issue in low socio-economic status individuals. The goal of this study was to evaluate bacterial quality and safety of some food items sold in street based on aerobic mesophilic bacteria, Salmonella, Staphylococcus aureus and Escherichia coli in Woldia town. Cross-sectional study was performed on some selected street vended foods from March 2019 to May 2019 in Woldia town. A total of 36 ready-to-eat food samples such as ‘Sambussa’, ‘Bonbolino’ and ‘Ambasha’ were collected for microbial analysis. Finding of the study indicates that 32(88.9 %) of the vendors were females, 28(77.7%) handled food with bare hands, 28(77.7%) vendors were washing their hands after toilet. The mean total count of aerobic mesophilic bacteria, Salmonella, Staphylococcus aureus and Escherichia coli was 4.5×102±5.2×101 CFUg-1, 1.5×102±4.5×101 CFUg-1, 1.1×102±1.4×101 CFUg-1 and 2×102±3.4×101 CFUg-1, respectively. The dominant bacterial isolate from the street vended foods was Escherichia coli (53.5%), followed by Salmonella (24.1%) and Staphylococcus aureus (22.4%). The result of this study demonstrates the non hygienic practices of the vendors in street vended foods showed high bacterial load. Therefore, the street vended foods were contaminated with food borne pathogenic bacteria that can create a potential risk to public health in the study area. In general, the bacterial quality of the food quality sold in street in Woldia town was very poor and needs especial attention to avoid bacterial contamination.

Background: Unsafe food hygiene poses threats for becoming disease transmission. The most common of foodborne pathogenic bacteria is Escherichia coli. The purpose of this study was to examine the association between food hygiene and the contamination of escherichia coli bacteria on school snack. Subejcts and Method: A cross-sectional study was conducted in Cakung, East Jakarta from December 2016 to January 2017. A sample of 60 food handlers from a total of 147 foods handlers’ population was selected by cluster sampling. The dependent variable was E. coli bateria. The independent variables were proper hand washing, food serving aids, proper equipment washing, types of selling facilities, sanitation facilities, the placement of cooked food, and food preparation. The data were collected by laboratory test result and questionnaire. The data were analyzed by multiple logistic regressions. Results: As many as 45% of the positive snacks were contaminated with E. coli bacteria. E. coli bacterial contamination on food was related to the practice of using food serving aids (OR= 5.00; 95% CI= 1.19 to 20.92; p= 0.044), a place to store cooked food (OR= 6.11; 95% CI = 1.73 to 21.59; p = 0.007) and method of presentation (OR = 7.14; 95% CI = 1.43 to 35.57; p = 0.002). Conclusion: The incidence of Escherichia coli contamination on food is related to the practice of using food serving aids, the placement of cooked food and food serving.

Feeding pets raw meat-based diets (RMBDs) is becoming increasingly popular but comes with a risk of pathogenic bacteria, including Shiga toxin-producing Escherichia coli (STEC). In humans, STEC may cause gastrointestinal illnesses, including diarrhea, hemorrhagic colitis (HC), and the hemolytic uremic syndrome (HUS). The aim of this study was to evaluate commercially available RMBDs with regard to the occurrence of STEC. Of 59 RMBD samples, 59% tested positive by real-time PCR for the presence of Shiga toxin genes stx1 and/or stx2. STECs were recovered from 41% of the 59 samples, and strains were subjected to serotyping and virulence gene profiling, using whole genome sequencing (WGS)-based methods. Of 28 strains, 29% carried stx2a or stx2d, which are linked to STEC with high pathogenic potential. Twenty different serotypes were identified, including STEC O26:H11, O91:H10, O91:H14, O145:H28, O146:H21, and O146:H28, which are within the most common non-O157 serogroups associated with human STEC-related illnesses worldwide. Considering the low infectious dose and potential severity of disease manifestations, the high occurrence of STEC in RMBDs poses an important health risk for persons handling raw pet food and persons with close contact to pets fed on RMBDs, and is of concern in the field of public health.

The street-vended fruit beverages are considered as a source of disease causing microorganisms despite their high consumer demand and nutritional value. The study was conducted for the assessment of antibiotic resistance food-borne pathogens in street-vended fruit beverages available in an industrial zone of Bangladesh. A total of 50 samples constituting five different types of street-vended fruit beverages were collected from Gazipur city of Bangladesh. All the samples were examined for total viable microbial count followed by isolation, identification and antibiogram profile of Escherichia coli and Staphylococcus aureus. The total viable microbial count ranged from 2.3 to 8.9 log cfu/ml suggesting a significant bacterial load that exceeds the maximum permitted level of microbial load for freshly extracted fruit juices. Of the 50 samples, 29 (58.0%) were appeared as Staphylococcus aureus positive and 24 (48.0%) samples were contaminated with Escherichia coli. Antibiogram profile revealed Staphylococcus aureus resistance to penicillin (82.8%), amoxicillin (75.9%) and oxacillin (17.2%). The resistance to β-lactam antibiotic like oxacillin indicates the presence of highly pathogenic Staphylococcus aureus which is obviously a potent public health issue. In contrary, Escherichia coli isolates were resistant to amoxicillin (100%) and erythromycin (100%). All the isolates were found highly susceptible to ciprofloxacin and gentamicin. The antibiotic resistance pattern of the isolated organisms could complicate the treatment of food-borne illness in people. Development of holistic approach and their effective application could ensure the hygienic quality of these beverages as well as the health standard of the consumers.

First Choice

Cow’s milk containing pathogenic bacteria is an important threat to the consumers. The objectives of the present study were to identify the bacterial agents of public health importance in milk samples (n=35) of different locations and to determine their sensitivity to different antibiotics. The milk samples were collected and transported aseptically and subsequently allowed for culture in bacteriological media, Gram’s staining and biochemical tests for the identification of bacterial species. The bacteria identified were Staphylococcus aureus, Escherichia coli and Salmonella typhi, and their prevalence, in case of vendor milk specimens (n=28), were 96.43%, 53.57% and 35.71% respectively, and of brand milk specimens (n=7), were 42.86 %, 28.57% and 0%, respectively. This suggests that cautionary measures should be taken for quality milk production and consumption. The antibiotic sensitivity test was done by disc diffusion method and the average inhibition zones, in case of Staphylococcus aureus, were 32 mm for oxytetracycline, 26 mm for amoxicillin, 35 mm for ciprofloxacin, 27 mm for cefotaxime, 30 mm for ceftriaxone, 30 mm for azithromycin, and 26 mm for erythromycin; in case of Escherichia coli, were 5 mm for oxytetracycline, 9 mm for amoxicillin, 22 mm for ciprofloxacin, 30 mm for cefotaxime, 31 mm for ceftriaxone, 15 mm for azithromycin, and 0 mm for erythromycin; in case of Salmonella typhi., were 25 mm for oxytetracycline, 24 mm for amoxicillin, 38 mm for ciprofloxacin, 31 mm for cefotaxime, 34 mm for ceftriaxone, 24 mm for azithromycin, and 0 mm for erythromycin. Therefore, ciprofloxacin and ceftriaxone may be the antibiotics of first choice, and cefotaxime and azithromycin may be the second choice among the test antibiotics for the treatment of illness caused by these bacteria.Asian J.

Abstract Background Antimicrobial resistance (AMR) is a major and growing global public health problem. The Cambodia Ministry of Health established a pilot laboratory-based AMR surveillance system for blood specimens in 2017. The objective of this study is to characterize AMR among pathogenic isolates from blood samples. Methods A retrospective analysis was performed using one year of data from a pilot AMR Surveillance system in Cambodia. Four blood culture isolate pathogens were included: Escherichia coli, Klebsiella pneumoniae, Salmonella Typhi /Salmonella Paratyphi A and Staphylococcus aureus. Blood culture isolates that were referred from eleven sentinel sites were analyzed at the National Public Health Laboratory for identification. Antibiotic susceptibility testing (AST) was done using disk diffusion, minimum inhibitory concentration method following Clinical Laboratory Standard Institute (CLSI) guidelines. Results Among 214 pathogenic isolates from blood samples, E.coli was the most common (56.1%), followed by Salmonella Typhi/Salmonella Paratyphi A (18.7%), Staphylococcus aureus (13.5%), and Klebsiella pneumoniae (11.7%). Methicillin Resistance Staphylococcus aureus (MRSA) was detected in half of the isolates. E.coli was resistant to ampicillin (94.4%), trimethoprim-sulfamethoxazole (84.5%), and ceftriaxone (79.2%). Salmonella Typhi was resistant to ampicillin (73.3%) and trimethoprim-sulfamethoxazole (60.0%) and Salmonella Paratyphi A were resistant to fluoroquinolones (91.7%). For last resort antibiotics, E.coli was resistant to carbapenem groups (3.2% for imipenem, 4.9% for meropenem, and 5.0% for ertapenem). Klebsiella pneumoniae was not resistant to any groups. Conclusion E.coli was found at high rates in blood samples and was resistant to common antibiotics used in Cambodia. These pilot data show the importance of establishing a national AMR surveillance system in Cambodia to monitor AMR trends following GLASS guidelines. Disclosures All Authors: No reported disclosures

Abstract Baseline studies are needed to identify environmental reservoirs of non-pathogenic but associating microbiota or pathogenic bacteria that are resistant to antibiotics and to inform safe use of freshwater ecosystems in urban and agricultural settings. Mesophilic bacteria and Escherichia coli were quantified and isolated from water and sediments of two rivers, one in an urban and one in an agricultural area near Christchurch, New Zealand. Resistance of E. coli to one or more of nine different antibiotics was determined. Additionally, selected strains were tested for conjugative transfer of resistances. Despite having similar concentrations of mesophilic bacteria and E. coli, the rivers differed in numbers of antibiotic-resistant E. coli isolates. Fully antibiotic-susceptible and -resistant strains coexist in the two freshwater ecosystems. This study was the first phase of antibiotic resistance profiling in an urban setting and an intensifying dairy agroecosystem. Antibiotic-resistant E. coli may pose different ingestion and contact risks than do susceptible E. coli. This difference cannot be seen in population counts alone. This is an important finding for human health assessments of freshwater systems, particularly where recreational uses occur downstream.
