RESUMO
Background and Aims: Access to safe drinking water, sanitation, and hygiene is a fundamental human right and essential to control infectious diseases. However, many countries, including Ethiopia, do not have adequate data to report on basic water, sanitation, and hygiene (WASH) services. Although contaminated drinking water spreads diseases like cholera, diarrhea, typhoid, and dysentery, studies on drinking water contamination risk levels in households are limited in Ethiopia. Therefore, closing this gap needs investigation. Methods: A community-based cross-sectional study was conducted. A total of 5350 households were included. A systematic, simple random sampling technique was used to select the participants. The information was gathered through in-person interviews using a standardized questionnaire. Furthermore, 1070 drinking water samples were collected from household water storage. Results: This investigation revealed that 9.8%, 83.9%, and 4.9% of households used limited, basic, and safely managed drinking water services, respectively. Besides, 10.2%, 15.7% and 59.3% of households used safely managed, basic and limited sanitation services, respectively. Yet, 10.6% and 4.2% of households used unimproved sanitation facilities and open defecation practices. Also, 40.5% and 19.4% of households used limited and basic hygiene services. On the other hand, 40.1% of households lacked functional handwashing facilities. In this study, 12.1%, 26.3%, and 42% of households' drinking water samples were positive for Escherichia coli, fecal coliforms, and total coliforms, respectively. Also, 5.1% and 4.5% of households' drinking water samples had very high and high contamination risk levels for E. coli, respectively. We found that 2.5% and 11.5% of households and water distributors had unacceptable fluoride concentrations, respectively. Conclusion: The majority of households in Bishoftu town lack access to safely managed sanitation, drinking water, and basic hygiene services. Many households' water samples had very high and high health risk levels. Hence, the government and partner organizations should implement water and sanitation safety plans.
RESUMO
BACKGROUND: Safe water supply is vital and can result in significant benefits to health. However, contaminated bottled water poses a great health risk due to the poor microbiological quality of water. METHODS AND MATERIALS: A retrospective study was conducted on 222 Bottled water samples collected from various regions of Ethiopia from January 2008 to December 2015, tested and recorded in Ethiopian Public Health Institute to determine heterotrophic plate count and Staphylococcus aureus by pour plate method; for coliforms using multiple tubes fermentation techniques; for mould and yeast count using spread method, and for Salmonellae and Shigella spp. using ES ISO 6579 and ES ISO 21567. The data was analyzed using SPSS 20 statistical package. RESULTS: Among the total samples examined from 44 brands, detections of heterotrophic plate count, mould, yeast, total and thermotolerant coliforms, Escherichia coli and Staphylococcus aureus were observed in 114 (51.4%), 33 (14.9%), 5 (2.3%), 2 (0.9%), 1 (0.5%), 1 (0.5%) and 1 (0.5%) samples respectively, but there were no detections of Salmonellae nor Shigellae species. CONCLUSION: About 40% of bottled water samples were mycologically and bacteriologically unsafe for human consumption. To prevent public health hazards, regular monitoring of bottled water using quality indicators should be a priority agenda.
