Purpose Home-made alcohol-related deaths are a significant public health issue which is often overlooked. To date, approximately 30 people have died following the consumption of home brewed alcoholic beverages in Botswana. The process of brewing such alcoholic beverages remains unmonitored and makes it difficult to pinpoint the cause of these deaths. Ethanol content in these beverages is thought to be high and therefore contributing towards the deaths. The aim of this research was to develop and validate a method for the quantification of ethanol in the different types of home-brewed alcoholic drinks of Botswana. Methods Twenty-six different samples of home-brewed alcoholic drinks were collected from local brewers in different districts of Botswana. A Liquid–Liquid Extraction-Gas Chromatography-Flame Ionization Detector method was optimized for extraction of ethanol using ethyl acetate and validated for accuracy, precision, repeatability, selectivity, linearity, limit of detection, limit of quantification, stability. Following this, the method used to measure the concentration of ethanol in the different home brewed beverages. Results The method demonstrated linearity in the concentration range of 2.5–60% v/v with correlation coefficient (R 2 ) of 0.996 and, was found to be precise with %RSD values ≤ 5%. Repeatability was acceptable with %RSD values ≤ 5%. Percentage recoveries were within 100%. No interference was observed from likely excipients commonly found in home brewed alcoholic beverages, demonstrating good selectivity. Limits of detection and quantification were found to be 0.37% v/v and 1.12% v/v respectively. The analysed samples were discovered to contain ethanol with concentrations ranging from 2.56 to 36% v/v. Conclusion A method for the quantification of ethanol in home-made alcoholic beverages of Botswana was developed and validated. It is simple, cheap, rapid and does not require sophisticated instruments.

“…Liquid biofuel, such as bioethanol, is a sustainable source of energy that can be used in truck engines, heating systems, etc. To optimize the energy efficiency [1] of biofuel combustion and to limit greenhouse gas emissions [2], it is important to know the water content in these biomaterials. Ideally, this measurement should be done in-line, in real time, and continuously, enabling a perfect monitoring of a production line [3].…”

A multi-probe sensor for water content analysis, in liquid biofuels, by using reflection and transmission measurements in microwave frequencies range, is proposed in this letter. As preliminary step and for a better understanding, the measurements were carried out with ethanol/water mixtures, which mimic bioethanol applications, at room temperature. In order to study water/alcohol mixtures, each of them was characterized using classical techniques like open ended coaxial probe or reflection/transmission coaxial line, before being tested in multi-probe sensors. At the end, the multiprobe sensor aims to be implemented in-line production in order to perform diagnosis of water in liquid biofuels.

AimMany fish species can harbour a wide range of pathogenic agents in their tissues. Of many pathogens, the parasitic nematode of genus Contracaecum, which resides in the tissues of fish species, can results in fish‐borne infections in humans. This study was planned to assess consumers' awareness of fish‐borne zoonoses in the fishing sites of Lake Chamo, Arba Minch, Ethiopia. The study was also aimed at demonstrating the zoonotic nematode, Contracaecum parasites in the Oreochromis niloticus and Lates niloticus fishes collected from Lake Chamo, Arba Minch, Ethiopia.Methods and ResultsAssessment of awareness about fish‐borne zoonoses was conducted in randomly selected participants (n = 162) using face‐to‐face interviews via a structured and semi‐structured questionnaire. Besides, 70 fishes (O. niloticus = 35 and L. niloticus = 35) were examined for the presence of larva of Contracaecum and other anisakid genera through standard dissection, pepsin‐hydrochloric acid digestion and microscopic observation. Consumers have inadequate awareness about fish‐borne zoonoses based on the answers they provided to the questions. The majority of respondents (82%) consume raw fish in the area. Of these, a significantly higher proportion were male (p < 0.001), completed their elementary or high school (p = 0.004), Orthodox Christian (p = 0.044), fishermen (p < 0.001) and participants without previous information about fish‐borne zoonoses (p < 0.001). Overall, of examined fishes (n = 70), n = 15 (21.4%, 95% CI, 12.8–33.2) were infected with Contracaecum larva. A significant (p = 0.028) higher infection prevalence was noted in L. niloticus (34.3%, 95% CI, 19.7–52.3) compared to O. niloticus (8.6%, 95% CI, 2.2–24.2). A unit gram addition in the total weight of fish would significantly raise the risk of Contracaecum infection by 1% (p < 0.001).ConclusionsThe presence of Contracaecum, a zoonotic nematode in the fishes, which are often preferred by consumers for raw dishes, designates a high risk of possible fish‐borne infections in the area. Thus, providing education and training for fishermen, visitors of the area, and local people who visit the area for fish consumption, it is inevitably important to minimize the risk. Furthermore, health workers should suspect fish‐borne infections, such as anisakidosis in patients who have a history of raw fish consumption in Arba Minch, Ethiopia.
