Sensory evaluation and microbial status of meat floss from West African Dwarf Goats fed graded levels of broiler litter

This study was conducted to evaluate the effects of dietary inclusion levels of Broiler Litter (BL) on meat quality of West Africa Dwarf (WAD) goats. Five complete diets were formulated using BL to replace 40 % composition of Cottonseed Cake (CSC) as dietary protein source at 0, 25, 50, 75 and 100 % levels, thus each level of replacement served as a treatment. Thirty WAD bucks with average weight of 10.57±0.42 kg were randomly allotted to five treatments in a randomized complete block design (RCBD). After feeding trials and digestibility studies, the bucks were humanly slaughtered and two kilograms of meat from uniform parts (hind leg and loin) of each buck were processed to Meat Floss (Dambun nama) and evaluated for proximate, sensory qualities and microbial status during storage for 60 days at room temperature. Twenty semi-trained panellists were used to evaluate the processed meat, using a five-point hedonic scale, Total Aerobic Plate Counts (TAPC) and Total Coliform Counts (TCC) was also determined. The result revealed that proximate nutrients composition of fresh Chevon was not significantly (p>0.05) different in all the treatments. The results of sensory parameters revealed that aroma, taste, colour, tenderness, juiciness and acceptability were significantly (p<0.05) affected by levels of BL inclusions. Similarly, there was also interaction (p<0.05) between levels of CSC replacement with broiler litter and time of storage of Dambun nama on sensory parameters. It was concluded that replacing up to 50 % of CSC with BL improved meat sensory qualities

Properties of Foodborne Pathogens and Their Diseases

Thousands of foodborne pathogens are causing a great number of diseases with significant effects on human health and economy. Foodborne pathogens can contaminate food items not only during production and processing, but also at the time of storage and transport before consuming. During their growth, these microorganisms are capable of secreting different type of toxins into the extracellular environment. Likewise, other harmful substances can be also released and can contaminate food after breakup of food pathogens. Many microbial toxins can withstand inactivation, and can endure harsh treatment during food processing. Many of these molecules are partaken in cellular processes and can display different mechanisms of pathogenesis of foodborne organisms. Thus studying the properties of foodborne pathogens can help in the understanding of their contamination and inactivation. In the present review, we discussed extensively on the properties of foodborne pathogens including bacteria, viruses and parasites. In addition, some of the diseases caused by foodborne pathogens and the mechanism of their pathogenesis were also discussed

Effects of social determinants on children’s health in informal settlements in Bangladesh and Kenya through an intersectionality lens: a study protocol

Introduction Several studies have shown that residents of urban informal settlements/slums are usually excluded and marginalised from formal social systems and structures of power leading to disproportionally worse health outcomes compared to other urban dwellers. To promote health equity for slum dwellers, requires an understanding of how their lived realities shape inequities especially for young children 0–4 years old (ie, underfives) who tend to have a higher mortality compared with non-slum children. In these proposed studies, we aim to examine how key Social Determinants of Health (SDoH) factors at child and household levels combine to affect under-five health conditions, who live in slums in Bangladesh and Kenya through an intersectionality lens. Methods and analysis The protocol describes how we will analyse data from the Nairobi Cross-sectional Slum Survey (NCSS 2012) for Kenya and the Urban Health Survey (UHS 2013) for Bangladesh to explore how SDoH influence under-five health outcomes in slums within an intersectionality framework. The NCSS 2012 and UHS 2013 samples will consist of 2199 and 3173 under-fives, respectively. We will apply Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy approach. Some of SDoH characteristics to be considered will include those of children, head of household, mothers and social structure characteristics of household. The primary outcomes will be whether a child had diarrhoea, cough, fever and acute respiratory infection (ARI) 2 weeks preceding surveys. Ethics and dissemination The results will be disseminated in international peer-reviewed journals and presented in events organised by the Accountability and Responsiveness in Informal Settlements for Equity consortium and international conferences. Ethical approval was not required for these studies. Access to the NCSS 2012 has been given by Africa Population and Health Center and UHS 2013 is freely availabl

Epidemiology, diagnostics and factors associated with mortality during a cholera epidemic in Nigeria, October 2020-October 2021: a retrospective analysis of national surveillance data.

OBJECTIVES: Nigeria reported an upsurge in cholera cases in October 2020, which then transitioned into a large, disseminated epidemic for most of 2021. This study aimed to describe the epidemiology, diagnostic performance of rapid diagnostic test (RDT) kits and the factors associated with mortality during the epidemic. DESIGN: A retrospective analysis of national surveillance data. SETTING: 33 of 37 states (including the Federal Capital Territory) in Nigeria. PARTICIPANTS: Persons who met cholera case definition (a person of any age with acute watery diarrhoea, with or without vomiting) between October 2020 and October 2021 within the Nigeria Centre for Disease Control surveillance data. OUTCOME MEASURES: Attack rate (AR; per 100 000 persons), case fatality rate (CFR; %) and accuracy of RDT performance compared with culture using area under the receiver operating characteristic curve (AUROC). Additionally, individual factors associated with cholera deaths and hospitalisation were presented as adjusted OR with 95% CIs. RESULTS: Overall, 93 598 cholera cases and 3298 deaths (CFR: 3.5%) were reported across 33 of 37 states in Nigeria within the study period. The proportions of cholera cases were higher in men aged 5-14 years and women aged 25-44 years. The overall AR was 46.5 per 100 000 persons. The North-West region recorded the highest AR with 102 per 100 000. Older age, male gender, residency in the North-Central region and severe dehydration significantly increased the odds of cholera deaths. The cholera RDT had excellent diagnostic accuracy (AUROC=0.91; 95% CI 0.87 to 0.96). CONCLUSIONS: Cholera remains a serious public health threat in Nigeria with a high mortality rate. Thus, we recommend making RDT kits more widely accessible for improved surveillance and prompt case management across the country

Improving accountability for equitable health and well-being in urban informal spaces: Moving from dominant to transformative approaches

This article critically reviews the literature on urban informality, inequity, health, well-being and accountability to identify key conceptual, methodological and empirical gaps in academic and policy discourses. We argue that critical attention to power dynamics is often a key missing element in these discourses and make the case for explicit attention to the operation of power throughout conceptualization, design and conduct of research in this space. We argue that: (a) urban informality reflects the exercise of power to confer and withhold advantage; (b) the dominant biomedical model of health poorly links embodied experiences and structural contexts; (c) existing models of accountability are inadequate in unequal, pluralistic governance and provision environments. We trace four conceptual and empirical directions for transformative approaches to power relations in urban health equity research

Sugarcane-derived animal feed

Sugarcane cultivation in the tropics and subtropics has been a matter of record for as long as written and pictorial records have survived the ravages of time, and it is undoubtedly true that the crop was cultivated by primitive humans long before. It is also undoubtedly true that cultivated sugarcane has been part of the diet of domesticated animals for a similar period of time and, to this day, crop residues from cultivated sugarcane are an important source of forage or supplementary fodder in the tropics and subtropics (Peacock 1996, Aregheore 2005). In contrast, commercial sugarcane production now occurs in more than 100 countries in an area of more than 26 million hectares (FAOSTAT 2014), and its cultivation generates the highest annual tonnage of biomass of any crop, approximately 1.84 billion tons (FAOSTAT 2014).With an increasing global demand for meat, milk, dairy, and other products derived from domesticated animals, there is an increasing demand for animal feed and an increasing need to integrate existing crop residues and processing products into animal feed. Given the prominence of sugarcane in global plant biomass production, it is clear that sugarcane has a significant role to play in increasing global animal production. Furthermore, modeling of integrated sugarcane and animal production shows that the approach can have substantial economic advantages (Gradiz et al. 2007). Sugarcane has significant advantages as a forage crop in the tropics and subtropics including - (i) adaptation to tropical and subtropical conditions; - (ii) reduced sensitivity to poor soil fertility, heat and humidity, and insect and disease pressures compared with other crops; - (iii) existing technology for production and processing at industrial scale; - (iv) high biomass yields can be achieved, and; - (v) the unusual ability to maintain consistent quality as a standing crop in the field (Pate et al. 2002). Indeed, there are examples of sugarcane cultivars that have been specifically bred to provide animal feed and thrive under region-specific environmental conditions (Suzuki et al. 2014). This chapter provides an overview of how sugarcane crop residues, the products of sugarcane processing, and the products of raw sugar production are being used to support animal production and describes technologies available to enhance them for this purpose
