The purpose of this study was to collect fermented milk samples and to document the processing and the house hold preservation methods of Omashikwa. The samples collected will be used to examine the antimicrobial properties of Lactic Acid Bacteria or LAB isolates with potential probiotic use in order to control and eliminate the spread of harmful bacteria in food products. A total of 13 samples were collected and 13 questionnaires were filled in. The first region visited was Ohangwena region in which one village was surveyed, then Omusati region; three villages, Oshana four villages lastly Oshikoto only two villages.

    SUMMARY: Research into Indigenous Knowledge System Technology (IKST) has been receiving increasing attention from various research institutions and Government Ministries in Namibia during the last five years. Indigenous communities in Namibia possess a rich traditional knowledge expressed in many practices in their communities. Indigenous wild edible fruits are available within the Namibian 13 regions which provide a rich source of vitamins and fibres for indigenous people’s diet. The aims of this study were to record the different IKST practices on the indigenous fruit trees in Ohangwena and Oshikoto regions. Three constituencies in Ohangwena region were surveyed; these including Okongo, Eanhana and Ondobe Constituencies. In Oshikoto region; only one constituency which is Onayena was included in the survey. A total of 65 respondents were interviewed; 54% women, 38% men and 8% both in group interviews. The majority of the people interviewed were in their thirty’s, with the youngest being 18 years old and the oldest being 98 years old. Thirty eight plant specimens were collected of which 24 are from Ohangwena and 15 from Oshikoto region, these specimens belong to 18 genuses and 23 species. Regarding to the indigenous knowledge; most of the respondents indicated that their knowledge on indigenous fruits was learnt mainly through their parents. Almost all of the respondents reported that the indigenous fruits and their products have social values such as it is presented to guests at special ceremonies, weddings, etc. In addition to their social values; health values have been reported also especially with regard to has flu. Some people depend on these fruits and their by-products to get income, for example Distilled liquor from Eembe (Berchemia discolor), Palm fruits (common practice in Oshikoto region). Most of the peoples reported that the traditional beer and wines are the main products made from these fruits.
