Abstract: Gari, a traditional African food made from cassava, is popular in the West
African sub-region. It is known as the students' companion due to its
consumption among high school students. However, there is limited data
on the microbial safety of Gari in Ghana. Staphylococcus aureus, a
common flora on human skin, can indicate the hygienic conditions of
contact foods. This research aimed to determine the presence of
Staphylococcus aureus and methicillin-resistant Staphylococcus aureus
(MRSA) in Gari sold in two Northern Region districts. Eighty (80) Gari
samples were aseptically collected from the markets within the Tamale
Metropolis and Tolon District. Baird-Parker media supplemented with egg
yolk, a selective media for Staphylococcus aureus, was used and
confirmed biochemically with catalase and coagulase tests. The
susceptibility test was conducted using the disk diffusion method
following EUCAST guidelines. The results showed that 50% of Gari
samples were positive for Staphylococcus aureus, with 95% of the 40
isolates being MRSA. Staphylococcus aureus isolates were highly
resistant to ceftazidime 97.5%, ampicillin 95%, cefoxitin 95%, ceftriaxone
95%, amoxicillin 95%, and tetracycline 35%, while the multi-drug
resistant pattern was 100%. The study reveals a high prevalence of Staphylococcus aureus in Gari sold in the Tamale metropolis and Tolon
District, requiring public education to reduce contamination levels. The
high rate of MRSA is a cause for concern and further investigation is
needed. Public education is to be required in the handling of Gari.2025-01-01T00:00:00ZA LIGHTWEIGHT DOWNSCALED APPROACH TO AUTOMATIC SPEECH RECOGNITION FOR SMALL INDIGENOUS LANGUAGESStan, G.

Abstract: Development of fully featured Automatic Speech Recognition (ASR) systems for a complete language vocabulary generally requires large data repositories, massive computing power, and a stable digital network infrastructure. These conditions are not met in the case of many indigenous languages. Based on our research for over a decade in West Africa, we present a lightweight and downscaled approach to AI-based ASR and describe a set of associated experiments. The aim is to produce a variety of limited-vocabulary ASRs as a basis for the development of practically useful (mobile and radio) voice-based information services that fit needs, preferences and knowledge of local rural communities.

Abstract: A majority of the world remain unconnected to the World Wide Web due to issues like low literacy and relevant information. This study presents Mr. Meteo, a system that provides weather information via voice calls in local languages to rural farmers in Ghana. The study used an interdisciplinary approach to identify relevant informational needs and socio-economic implications, and early end-user and stakeholder involvement. Mr. Meteo was deployed in Bolgatanga, Ghana and represents a novel design in terms of actual web data access to rural areas. The positive feedback from farmers, and stakeholder’s interest in continuity, shows this approach to be an appropriate method of development and implementation of information systems for rural areas; successful due to end-user and stakeholder involvement, focus on existing technologies, the use of voice technologies to mitigate the problem of illiteracy, and information relevance to end-users. This paper presents the methodology and results of this novel, practical, local-context ICT4D project,that has produced a viable information system for rural communities
