Commercially reared ostriches at Msengi farm situated in the Chinhoyi area of Mashonaland West province in Zimbabwe were found to be infected with the 'oriental eye fluke', <em>Philopthalmus gralli</em>, in 2001. This was the 1st record of the fluke in Zimbabwe. Trials were conducted to identify a suitable drug for the treatment of this fluke. A total of 12 ostriches confirmed to be infected with the fluke through clinical examination of the eyes and identification of the fluke were randomly divided into 3 equal groups, with each group receiving a different treatment protocol. The 3 drugs used were doramectin, levamisole and closantel. Each of the drugs was used in combination with chloramphenicol as an eye ointment. Levamisole was administered topically into the eye whereas doramectin and closantel were administered parenterally as an intramuscular injection. The results indicated a positive response in levamisole-treated birds but there were no noticeable responses to doramectin and closantel treatments

PurposeIn response to food supply constraints resulting from coronavirus disease 2019 (COVID-19) restrictions, in the year 2020, the project developed automated household Aquaponics units to guarantee food self-sufficiency. However, the automated aquaponics solution did not fully comply with data privacy and portability best practices to protect the data of household owners. The purpose of this study is to develop a data privacy and portability layer on top of the previously developed automated Aquaponics units.Design/methodology/approachDesign Science Research (DSR) is the research method implemented in this study.FindingsGeneral Data Protection and Privacy Regulations (GDPR)-inspired principles empowering data subjects including data minimisation, purpose limitation, storage limitation as well as integrity and confidentiality can be implemented in a federated learning (FL) architecture using Pinecone Matrix home servers and edge devices.Research limitations/implicationsThe literature reviewed for this study demonstrates that the GDPR right to data portability can have a positive impact on data protection by giving individuals more control over their own data. This is achieved by allowing data subjects to obtain their personal information from a data controller in a format that makes it simple to reuse it in another context and to transmit this information freely to any other data controller of their choice. Data portability is not strictly governed or enforced by data protection laws in the developing world, such as Zimbabwe's Data Protection Act of 2021.Practical implicationsPrivacy requirements can be implemented in end-point technology such as smartphones, microcontrollers and single board computer clusters enabling data subjects to be incentivised whilst unlocking the value of their own data in the process fostering competition among data controllers and processors.Originality/valueThe use of end-to-end encryption with Matrix Pinecone on edge endpoints and fog servers, as well as the practical implementation of data portability, are currently not adequately covered in the literature. The study acts as a springboard for a future conversation on the topic.
