    Microbiological Quality of Traditionally Smoked Fish from Lake Victoria Crescent, Uganda
    (Food Science and Quality Management, 2021) Abigaba, Rubaijaniza; Nakavuma, Jessica L.; Kankya, Clovice; Kabasa, John D.
    Microbiological quality of traditionally smoked fish was assessed to ascertain the effectiveness of traditional smoking process and handling conditions for smoked fish shelf-life and safety. Fish smoking is a popular preservation method in Uganda. Although fish smoking is a widely used method of preservation, the presence of spoilage and pathogenic bacteria in smoked fish and food borne illnesses remain a threat in developing countries. However, little is known about microbial quality of fish smoked from Uganda. In light of this, the status of spoilage, hygiene and pathogenic indicator organisms in fish (Nile perch) was investigated. A total of 75 randomly selected fresh, freshly smoked, and on shelf smoked fish from landing sites and markets respectively, were obtained for microbial and moisture content analysis. Descriptive statistics was used to present the data, while ANOVA and Tukey tests were used to analyze the data. The study revealed that, the smoking process significantly (P<0.05) reduced microbial load in freshly fish to levels acceptable for consumption, despite the high levels of moisture content in the range of 59.2% to 66.5%. The mean microbial load (log of cfu/g) of indicator organisms for samples from different sites varied from; 9.97 to 10.18; 7.39 to 8.19 (aerobic mesophilic bacteria or TPC), 5.18 to 5.27; 0 to 4.28 (total coliforms), 2.73 to 5.55; 0 to 0.85 (E. coli), 4.97 to 7.32; 0 to 3.11 (S. aureus), and 2.21 to 4.56; 0 to 0.82 (Yeasts and molds), for fresh and smoked fish samples respectively. Additionally, mean microbial load for on shelf smoked fish from markets varied from; 8.2 to 10.57 (TPC), 2.8-6.63 (total coliforms), 0 to 6.11 (E. coli), 6.74 to 8.89 (S. aureus), and 0 to 5.51 (Yeasts and molds). Although findings showed that, traditional fish smoking was somewhat effective in reducing microbial load to acceptable levels, the microbial status of on shelf smoked fish indicated poor fish handling and storage. Therefore, proper fish handling during and post-smoking as well as cooking before consumption, are highly recommended for assured shelf-life and safety of smoked fish for consumption in Uganda.

    Traditional plants used for Medicinal purposes by local communities around the Northern sector of Kibale National Park, Uganda
    (Elsevier, 2011) Namukobe, Jane; Kasenene, John.M.; Kiremire, Bernard T.; Byamukama, Robert; Kamatenesi-Mugisha, Maud; Krief, Sabrina; Dumontet, Vincent; Kabasa, John D.
    Ethnopharmacological relevance: The study was done to establish medicinal plants used in the treatmentof various diseases by the people in the Northern sector of Kibale National Park in western Uganda. Itwas also aimed at establishing the plant parts used and the mode of preparation of remedies. Theseplants create a basis for phytochemical evaluation which can lead to the discovery of biologically activecompounds that can be used as starting materials in the development of new drugs targetingselected diseases such as malaria. Materials and methods: The required information was obtained using open interviews, semi-structured questionnaires, focus group discussions and transect walks. Results: Different medicinal plants (131 species) distributed over 55 families were observed to be used by the local communities around the Northern sector of Kibale National Park. The plants as reported in this paper are used to treat 43 physical illnesses/diseases. The most used parts of the plants are the leaves. Water is the main medium used for the preparation of the remedies which are mostly administered orally. Conclusion: The people in the study area have a rich heritage of traditional plants that are used in the health care system to treat diseases. These medicinal plants have contributed significantly to several disease therapies. The most common diseases treated are malaria and cough, which are mostly treated by Vernonia amygdalina Del. and Albizia coriaria Welw. respectively. The main sources of medicinal plants include bush land, home gardens, grasslands, and the forest.
