This retrospective study was aimed to examine the distribution of some physicochemical parameters and its health impact in selected drinking water sources of Ethiopia. The study used 983 water samples collected from different regions of the country, and have been tasted in the Environmental Health Laboratory, Ethiopian Public Health Institute, from 2003 to 2011. The samples were collected from eight regions plus two administrative cities of the country and classified based on the source type as spring, well, and tap water. The physicochemical parameter analysis was executed based on standard method. Microsoft Excel and IBM SPSS Statistical software were used for the statistical analysis of median and graph. The median result indicates that some values are within the acceptable range (PH, magnesium, chloride and sodium from spring and tap water), but, there are some measured values in some regions which are out of the recommended limit, (total hardness and calcium in spring, tap and well water). On the other hand, very high Sodium and chloride concentration were recorded in spring, tap, and well water sources of the region such as Somali, Afar, and Oromia. Those water sources that do not conform to National Standard will result in public health problem in long time exposure. Therefore, the local water authority shall strengthen local water quality monitoring and control system as well as risk assessment and management mechanisms.

Garden cress seed is a potential source of macro and micronutrients including essential fatty acids and amino acids as well as minerals such as iron, potassium, calcium and phosphorus. The seed also provides appreciable amount of health-protective bioactive compounds used to treat diabetes, hypercholesterolemia, bone fracture, asthma, constipation and some forms of cancer. Besides,, it is used to develop functional foods of therapeutic value in food manufacturing industries and traditional food preparations. Even though, it is known for its superior health benefits, provision of essential nutrients, and wider application in functional food development it is among the most underutilized crop in the world. Additionally, majority of studies conducted on garden cress seeds are mainly animal trials and hence needs to conduct studies on human. Therefore, the aim of this review paper is to provide up to date research evidence on the nutrient composition and therapeutic use of underutilized garden cress seeds and its functional food products, promising for the prevention of non-communicable and communicable diseases. Graphical Abstract

Poor food handling practice is a key cause of foodborne diseases notably in developing countries like Ethiopia. This study aimed to assess food safety knowledge, attitude and practice of food handlers, establishments' status and determinants of safe food handling practice. The study utilized institution based cross-sectional study among food handlers working in Cafeterias, Restaurants and Hotels in Yeka sub city, Addis Ababa. A total of 284 food handlers: 69 from Cafeterias, 89 from Restaurants and 126 from non-stared Hotels were enrolled using stratified random sampling technique. Data were collected in observational checklist and through structured-questionnaire via face to face interview. A binary and multivariate logistic regression was used and adjusted for cofounders. A P-value of less than 0.05 was considered statistically significant. The present study has indicated 42.6% of food handlers had good food handling practice. Food handling practice in the establishments were significantly associated with sex, monthly income, availability of functional pipe water supply, availability of soap and/or detergents and presence of insects or rodents. Food handlers in the study area were executing in a poor food handling practice, as most of them were not knowledgeable as needed. In fact, revising the salary of food handlers based on their work load could be valid, as there is existing worldwide economic inflation. Likewise enhancing pipe water availability in the food premises and dispatching sufficient soaps and detergents coupled with eradicating ubiquitous insects and rodents are key.

Better macro and micro nutrient status and their adequate intake by the athletes have great role in balancing losses associated with strenuous exercise, then for better performance. The objective of this study was to determine iron, folate and vitamin B₁₂ status of Ethiopian professional athletes. A cross sectional study was conducted using a point time convenient sample of 101 male and female Ethiopian professional athletes of different distance categories in the period of February to April 2014. Biochemical samples, detail health and exercise related interview, performance data, 24 h dietary diversity and weekly food frequency were collected. The low, medium and high dietary diversity terciles were 36.1, 60.9 and 3.3 % respectively. The mean ± Sd of dietary diversity was 5.44 ± 1.8. Prevalence of iron overload (Serum ferritin >200 μg/L) was 11 %, whereas that of anemia (Hb < 12 g/dL), iron deficiency (ferritin < 12 μg/L) and moderate folate deficiency (210 pg/ml). The iron status of male athletes was significantly different by running-distance categories. In contrast, such difference was absent for female athletes. Performance of the athletes was associated with their red blood cell count (RBC) at p = 0.03. The high performer athletes exhibited high mean value of micronutrient status and hematological variables than their counter parts. However, the RBC of the athletes was the only parameter whose association was statistically significant. The observed gender difference in the association of running-distance category with iron and folate in this study needs further investigation. Given the 11 % iron overload in the present study; there is a need of awarance creation activities and diet intervention in the athletics federation, the athletes and the coaches in order not aggravate the present overload. Prescription of supplements such as iron-folate, multivitamins and minerals should not be based on broad spectrum rather it should be based on recent history of confirmed deficiency, clinical signs and/or laboratory testing to prevent trace element toxicity.

Background. The Akaki River in Ethiopia has been found to contain elevated levels of several metals. Our objectives were to characterize metals exposures of residents living near the Akaki River and to assess metal levels in their drinking water. Methods. In 2011, we conducted a cross-sectional study of 101 households in Akaki-Kality subcity (near the Akaki River) and 50 households in Yeka subcity (distant to the Akaki River). One willing adult in each household provided urine, blood, and drinking water sample. Results. Urinary molybdenum (), tungsten (), lead (), uranium (), and mercury () were higher in Akaki-Kality participants compared to Yeka participants. Participants in both subcities had low urinary iodine; 45% met the World Health Organization (WHO) classification for being at risk of moderate iodine deficiency. In Yeka, 47% of households exceeded the WHO aesthetic-based reference value for manganese; in Akaki-Kality, only 2% of households exceeded this value (). There was no correlation between metals levels in water samples and clinical specimens. Conclusions. Most of the exposures found during this investigation seem unlikely to cause acute health effects based on known toxic thresholds. However, toxicity data for many of these metals are very limited.

Background: The continued provision of safe food, free of aflatoxin remains a huge challenge in developing countries. Despite several favourable climatic conditions that facilitate aflatoxin contamination in Ethiopia, there is little information showing aflatoxin exposure in children. Therefore, this study assessed aflatoxin exposure among young children in Butajira district, South-Central Ethiopia. Methods: Community based cross-sectional study stratified by agro-ecology was employed in Health and Demographic Surveillance Site (HDSS) of Butajira. The study included 332 children aged 12–59 months and were selected by simple random sampling technique using the HDSS registration number as a sampling frame. We collected data on dietary practice and aflatoxin exposure. Aflatoxin M1 concentration in urine was measured by Enzyme-Linked Immunosorbent assay (ELISA). The data analysis was carried out using STATA. Results: Detectable urinary Aflatoxin M1 was found in 62.4% (95% CI: 56.9 – 67.5%) of the children at a level ranging from 0.15 to 0.4 ng/ml. Children living in lowland agro-ecological zone had [AOR = 2.11 (95% CI; 1.15, 3.88] odds of being exposed to aflatoxin as compared to children living in highland agro-ecological zone. Children at lower socio-economic status [AOR = 0.27 (95% CI; 0.14, 0.50] and medium socio-economic status [AOR = 0.47 (95% CI; 0.25, 0.87] had 73% and 53% lower odds of being exposed to aflatoxin as compared to children in the higher socio-economic status, respectively. Conclusions: Aflatoxin exposure among young children was very high in South-Central Ethiopia. This high aflatoxin exposure might emphasize the need for aflatoxin exposure mitigation strategies in Ethiopia. Especially, raising awareness of the community towards aflatoxin exposure is very crucial. In addition, further research is required to assess long-term aflatoxin exposure and its association with child growth and development.
