The presence of Salmonella in food products and emergence of antibiotic resistance are the major challenges facing public health policies. A total of 2749 crocodile meat samples obtained from the Central Veterinary Laboratories in Zimbabwe were screened for Salmonella specieswere collected from three Zimbabwean commercial farms between the year 2012 and 2019 for a retrospective observational study to determine the prevalence and magnitude of antibiotics resistant Salmonella species in crocodile meat. The isolation of Salmonella was in accordance with the ISO 6579:2002 and the antibiotic susceptibility testing was carried out based on Clinical and Laboratory Standard Institute’s recommendations by means of the Kirby-Bauer disk diffusion method. SILAB Database was used to determine the prevalence of Salmonella species. Prevalence was stratified by year and farms. Twenty Salmonella isolates were identified using biochemical tests, and 15 were confirmed by polymerase chain reaction (PCR). Antimicrobial susceptibility profiles of the confirmed Salmonella isolates were examined using 14 antibiotics. The overall prevalence of Salmonella species in crocodile meat samples was 0.5%. The prevalence of Salmonella species ranged from 0.04% to 0.44% in the crocodile meat samples and annual prevalence ranged from 0.01% to 1%. The highest prevalence of Salmonella (4.4%) was recorded in the year 2012. Salmonella isolates from one of the three tested farms were resistant to Erythromycin (73.33%), Ampicillin (80%), and Penicillin G (100%). Generally, Salmonella isolates displayed lower resistance to Cefepime, Ceftriaxone, Amikacin, Tetracycline, Ertapenem, Florfenicol, and Erythromycin (0-53.33%) whereas all Salmonella isolates showed susceptibility to Cefepime, Ceftriaxone, Ertapenem, and Florfenicol. Although the study indicates low prevalence of Salmonella species in crocodile meat, there is a need for strict implementation of Hazard Analysis Critical Control Point (HACCP) to reduce contamination rates in meat and its products

The research follows on the Arusha declaration of 2005 and the global financial crisis of 2008 and explored the impediments and the evolution of derivatives in Sub Sahara Africa with special attention onZimbabwe, Botswana and South Africa. The research has been based on a review of literature of the seminal authors and through a conduct of questionnaire surveys in each of the three countries of Zimbabwe, Botswana and South Africa. The purpose of the study was to identify any disparities in the evolution of commodities and financial derivatives in the Sub-Saharan African countries. The study uncovered that registered banks in Botswana and Zimbabwe relied so much on the forward agreement to protect against financial risk. Credit default swaps (CDS), currency options and simple foreign exchange swaps also were relatively used in Botswana by most commercial banks to hedge against risk. In South Africa, a wide variety of simple and complex futures and options products are effectively applied on commodities and currencies to protect against financial losses. Rodrigues, Schwarz and Seeger (2012) noted that the initiation of formal derivative markets can accelerate growth in the economies and decrease the fluctuations of the Gross Domestic Product.

EditorialThe first 11 articles in the first issue of 2014 deal with global legal topics ranging from outer space to domestic South African matters and legal challenges in other African countries, such as Uganda, Nigeria and Zimbabwe. Anél Ferreira-Snyman discusses legal challenges relating to the commercial use of outer space, with specific reference to space tourism. She points out that the current legal framework is outdated and no longer deals adequately with the rapidly developing space tourism industry. Further away from the moon, although it deals with creations of the mind and is just as mysterious for the average person, is the contribution of André van der Walt and Richard Shay, which analyses the South African Constitutional Court's treatment of intellectual property. They focus on the methodology that the Court has formulated to assess if state interference complies with constitutional provisions to determine if state intervention into property interests has been legitimate. The third contribution, by Joel Baloyi, also deals with a creation of the mind, namely copyright. He attempts through a comparative analysis to demystify the role of copyright as a tool for economic development in Africa and criticises the stifling effect the transferability principle has on the effectiveness of copyright in certain African countries. Bradley Slade discusses the differences between the concepts "public purpose" and "public interest" in the context of third party transfers as a result of property being expropriated for the realisation of public purposes in the fourth contribution. The influence of the Constitution of South Africa, 1996 on organ transplants is the topic of the fifth contribution, by Debbie Labuschagne and Pieter Carstens. They come to the conclusion that the South African government has failed to provide an effective legal framework to relieve the shortage of human organs available for transplantation. Sixthly, Lize Mills discusses recently proposed regulations prohibiting the advertising and promotion of infant formulae and other products marketed as being suitable for infants or young children with the purpose of promoting breast-feeding. The last five articles move further afield and deal with legal issues elsewhere in Africa. Dana van der Merwe gives a comparative overview of the relationship between digital information in certain legal fields in South Africa and Uganda. Nazreen Shaik-Premanov examines Zimbabwe's Marange conflict diamond situation and Lovemore Chiduza analyses the Zimbabwean constitutional provisions on judicial independence. Peter Obutte scrutinises ICT laws in Nigeria and the last two authors, Serges Kamga and Ogechukwu Ajoku, reflect on addressing human rights violations by extractive industries in both South Africa and Nigeria.Four notes are also published in this issue. The first one is an overview article by Christa Rautenbach dealing with the modern-day impact of cultural and religious diversity as reflected in the book on "Managing Family Justice in Diverse Societies". The other four notes are case discussions. The first one is a discussion of the case of Government of the Republic of Zimbabwe v Louis Karel Fick by Erika de Wet. The second one is a discussion of the case of Le Sueur v eThekwini Municipality by Warren Freedman, and the last one is a discussion of the case of Apollo Tyres v South Africa (Pty) Ltd v CCMA by Shamier Ebrahim.Editor: Prof C Rautenbach

In sub-Saharan Africa (SSA), off-veld ruminant livestock and commercial poultry production fail to meet the demand for meat and eggs. Intensified production to meet the demand requires nutritionally balanced feeds. Competition between humans, livestock and poultry for feed resources present a challenge hence the need for alternative feed resources. Indigenous trees seeds are potential sources of nutrients. Senna siamea, widely distributed in SSA, produces an abundance of seed. We evaluated, by chemical analyses, the potential of hulled (HSSM) and dehulled (DSSM) in S. siamea seed meal to supply nutrients in feeds. DSSM had higher DM, CP, EE, ash, P and gross energy (92.71±0.08%, 47.89±0.03%, 11.39±0.16%, 6.17±0.07%, 1.01±0.03% and 23.13±0.05 MJ/kg DM, respectively) content than HSSM (P<0.05). Amino acids were more concentrated (P<0.05) in the DSSM. HSSM’s CF, NDF, ADF and Ca content was significantly higher (P<0.05) compared to that of the DSSM. The DM, CP, EE and gross energy (GE) content (89.48±0.09%, 21.75±0.09%, 4.71±0.41%, and 20.46±0.04 MJ/kg DM, respectively) of the HSSM though lower compared to in DSSM, are within range of conventional plant-derived dietary protein and energy sources for feeds. DSSM’s CP and GE is higher than that of conventional dietary protein and energy sources for feeds. The TSFAs (27.88±1.36% vs 27.53±0.59%) and TPUFAs (50.42±5.18% vs 53.42±2.12%) proportion of the HSSM and DSSM, respectively were similar. HSSM (21.69±0.18%) had a significantly higher proportion of TMUFAs than DSSM (19.03±0.21%). DSSM had a higher concentration of the fatty acids per unit mass since it had more than double EE content of the HSSM. In HSSM and DSSM palmitic (19.18±0.44% vs 18.63±0.37%), oleic (21.15±0.09% vs 18.45±0.01%) and linoleic acid (43.35 vs 50.62%), respectively were the dominant saturated, monounsaturated and polyunsaturated fatty acids. S. siamea seed meals can potentially be exploited as oleic- and linoleic acid-rich dietary energy and protein sources in livestock and poultry feeds.

The baobab tree represents a major contribution to rural communities of the south-east lowveld of Zimbabwe. The livelihood base of the study area was largely rain-fed subsistence farming whose production has declined due to frequent droughts. Harvesting of baobab tree products; leaves, fruits and bark fibre, has prospered due to poverty. These products are harvested for food, medicinal use, cash and animal harness. A mixed method approach on collection of data was employed through questionnaires, semi-structured interviews, 48-hour dietary recall and Household Food Insecurity Access Prevalence (HFIAP) template. Sixty-eight households from Wengezi and Gudyanga communities participated in this study. All the respondents from the study area indicated they were involved in using baobab products in one way or the other. According to the information collected by the HFIAP template, 76% of the households were moderate to severe food insecure. Baobab bark harvesting was common in the Gudyanga and harvesters were aware of sustainable way of harvesting it. Value-addition on baobab fruit pulp to make ice-lollies and seeds roasted to produce a coffee substitute was practised by youth projects with the help of a non-governmental organisation. Ninety-five percent of the households in the study area were in support of the idea of possible baobab tree commercial cultivation in the community. The support was in anticipation of job opportunities and reduced food insecurity.<br>Agriculture and  Animal Health<br>M. Sc. (Agriculture)
