Assessment of food safety practices among cassava processors in selected rural communities of Oyo State, Nigeria

Food safety assessment is an effective means of discovering knowledge and data gaps that limit effective risk analysis and at the same time providing information to develop public policies on food safety management. The study assessed the cassava food safety practices among cassava processors in selected rural communities of Oyo State. Both qualitative and quantitative research designs were used to examine the following parameters: knowledge, attitude, sources of information and constraints to food safety practices. Focus Group Discussion, In-depth Interview, direct observation and interview schedule were the sources of primary data used. Multi-stage sampling technique was used to select one hundred and fifty-four (154) men and women involved in cassava processing from four Local Government Areas where there is concentration of cassava production and processing activities in the state, namely: Saki-West, Saki-East, Atisbo and Afijio. Data were analyzed using percentage, mean, Analysis of Variance and Chi square. The findings revealed that the mean income was N20,695, majority of the processors have low knowledge (71.4%) and unfavourable attitude (51.3%) towards cassava safety practices. Public sanitary officers (x̅ = 2.61) and fellow processors (x̅ = 2.11) were ranked as the most used sources of information about cassava safety practices. Constraints to food safety practices include: processing is time consuming, the cumbersome nature of the safety practices and inadequate access to clean water. Inferential analysis of results shows that income contributed significantly to the cassava food safety practices (p = 0.04) and safety practices do significantly differ among cassava processors across the selected cassava processors (p = 0.10). However, no significant relationship between sex (p = 0.42), age (p = 0.48), marital status (p = 0.67), educational level (p =0.53), processing experience (p = 0.92) and safety practices of the respondents. Training and effective monitoring by relevant stakeholders will further boost processors’ knowledge and attitudinal change towards food safety and ultimately safe food for the consumers.Keywords: Assessment, Food, Safety, Practices, Processors, Cassava, Rural, Communit

Barriers and opportunities for evidence-based health service planning: the example of developing a Decision Analytic Model to plan services for sexually transmitted infections in the UK

Decision Analytic Models (DAMs) are established means of evidence-synthesis to differentiate between health interventions. They have mainly been used to inform clinical decisions and health technology assessment at the national level, yet could also inform local health service planning. For this, a DAM must take into account the needs of the local population, but also the needs of those planning its services. Drawing on our experiences from stakeholder consultations, where we presented the potential utility of a DAM for planning local health services for sexually transmitted infections (STIs) in the UK, and the evidence it could use to inform decisions regarding different combinations of service provision, in terms of their costs, cost-effectiveness, and public health outcomes, we discuss the barriers perceived by stakeholders to the use of DAMs to inform service planning for local populations, including (1) a tension between individual and population perspectives; (2) reductionism; and (3) a lack of transparency regarding models, their assumptions, and the motivations of those generating models

Detection of Escherichia coli O157 and Escherichia coli O157:H7 by the immunomagnetic separation technique and stx1 and stx2 genes by multiplex PCR in slaughtered cattle in Samsun Province, Turkey

This study was conducted to investigate the presence of Escherichia (E.) coli O157 and E. coli O157:H7 and stx1 and stx2 genes on cattle carcasses and in rectal samples collected from Samsun Province of Turkey. A total of 200 samples collected from cattle carcasses and the rectal contents of 100 slaughtered cattle from two commercial abattoirs were tested using the immunomagnetic separation technique and multiplex PCR methods. E. coli O157 and E. coli O157:H7 were detected in 52 of the 200 samples (26%) tested. Of the positive samples, 49 were E. coli O157 and three were E. coli O157:H7. The E. coli O157 strain was isolated from 24 carcasses and 25 rectal samples, while E. coli O157:H7 was isolated from two carcasses and one rectal sample. Of the 49 samples positive for E. coli O157, 32 were from the rectal and carcass samples of the same animal, while two E. coli O157:H7 isolates were obtained from rectal swabs and carcasses of the same animal. The stx1 and stx2 genes were both detected in 35 E. coli O157 isolates and one E. coli O157:H7 isolate, but the stx2 gene was only detected alone in two E. coli O157 isolates. Overall, 16 carcasses tested positive for E. coli O157 and one carcass tested positive for E. coli O157:H7 based on both carcass and rectal samples. Overall, the results of this study indicate that cattle carcasses pose a potential risk to human health due to contamination by E. coli O157 and E. coli O157:H7 in the feces

From Unpleasant to Unbearable - Why And How to Implement an Upper Limit to Pain And Other Forms of Suffering in Research with Animals

The focus of this paper is the requirement that the use of live animals in experiments and in vivo assays should never be allowed if those uses involve severe suffering. This requirement was first implemented in Danish legislation, was later adopted by the European Union, and has had limited uptake in North America. Animal suffering can arise from exposure to a wide range of different external and internal events that threaten biological or social functions, while the severity of suffering may be influenced by the animals’ perceptions of their own situation and the degree of control they are able to exert. Severe suffering is more than an incremental increase in negative state(s) but involves a qualitative shift whereby the normal mechanisms to contain or keep negative states at arm’s length no longer function. The result of severe suffering will be a loss of the ability of cope. The idea of putting a cap on severe suffering may be justified from multiple ethical perspectives. In most, if not all, cases it is possible to avoid imposing severe suffering on animals during experiments without giving up the potential benefits of finding new ways to cure, prevent, or alleviate serious human diseases and generate other important knowledge. From this it follows that there is a strong ethical case to favor a regulatory ban on animal experiments involving severe suffering

A checklist for health research priority setting: nine common themes of good practice

Health research priority setting processes assist researchers and policymakers in effectively targeting research that has the greatest potential public health benefit. Many different approaches to health research prioritization exist, but there is no agreement on what might constitute best practice. Moreover, because of the many different contexts for which priorities can be set, attempting to produce one best practice is in fact not appropriate, as the optimal approach varies per exercise. Therefore, following a literature review and an analysis of health research priority setting exercises that were organized or coordinated by the World Health Organization since 2005, we propose a checklist for health research priority setting that allows for informed choices on different approaches and outlines nine common themes of good practice. It is intended to provide generic assistance for planning health research prioritization processes. The checklist explains what needs to be clarified in order to establish the context for which priorities are set; it reviews available approaches to health research priority setting; it offers discussions on stakeholder participation and information gathering; it sets out options for use of criteria and different methods for deciding upon priorities; and it emphasizes the importance of well-planned implementation, evaluation and transparency

The fields of HIV and disability: past, present and future

This article provides an historic overview of the fields of disability and HIV. We describe this area of concern in terms of "fields" versus "a single field" because of the two related but distinct trends that have evolved over time. The first field involves people living with HIV and their experiences of disability, disablement and rehabilitation brought on by the disease and its treatments. The second involves people with disabilities and their experiences of vulnerability to and life with HIV. These two fields have evolved relatively independently over time. However, in the final section of this article, we argue that the divide between these fields is collapsing, and that this collapse is beginning to produce a new understanding about shared concerns, cross-field learning and the mutual benefits that might be realized from integrating policy and programmatic responses. We close by identifying directions that we expect these merging fields to take in the coming years

Under-regulated and unaccountable?:Explaining variation in stop and search rates in Scotland, England and Wales

From a position of near parity in 2005/6, by 2012/13 recorded search rates in Scotland exceeded those in England/Wales seven times over. This divergence is intriguing given the demands placed on the police, and the legal capacity to deal with these are broadly similar across the two jurisdictions. The aim of this paper is to unpack this variation. Using a comparative casestudy approach, the paper examines the role of structural ‘top-down’ determinants of policing: substantive powers of search, rules and regulations, and scrutiny. Two arguments are presented. First, we argue that the remarkable rise of stop and search in Scotland has been facilitated by weak regulation and safeguards. Second, we argue that divergence between the two jurisdictions can also be attributed to varying levels of political and public scrutiny, caused, in part, by viewing stop and search almost exclusively through the prism of ‘race’. In Scotland, the significance of these factors is made evident by dint of organisational developments within the last decade; by the introduction of a target driven high-volume approach to stop and search in Strathclyde police force circa 1997 onwards; and the national roll-out of this approach following the single service merger in April 2013. The salient point is that the Strathclyde model was not hindered by legal rules and regulations, nor subject to policy and political challenge; rather a high discretion environment enabled a high-volume approach to stop and search to flourish

Cost-effectiveness analysis of guidelines for antihypertensive care in Finland

<p>Abstract</p> <p>Background</p> <p>Hypertension is one of the major causes of disease burden affecting the Finnish population. Over the last decade, evidence-based care has emerged to complement other approaches to antihypertensive care, often without health economic assessment of its costs and effects. This study looks at the extent to which changes proposed by the 2002 Finnish evidence-based Current Care Guidelines concerning the prevention, diagnosis, and treatment of hypertension (the ACCG scenario) can be considered cost-effective when compared to modelled prior clinical practice (the PCP scenario).</p> <p>Methods</p> <p>A decision analytic model compares the ACCG and PCP scenarios using information synthesised from a set of national registers covering prescription drug reimbursements, morbidity, and mortality with data from two national surveys concerning health and functional capacity. Statistical methods are used to estimate model parameters from Finnish data. We model the potential impact of the different treatment strategies under the ACCG and PCP scenarios, such as lifestyle counselling and drug therapy, for subgroups stratified by age, gender, and blood pressure. The model provides estimates of the differences in major health-related outcomes in the form of life-years and costs as calculated from a 'public health care system' perspective. Cost-effectiveness analysis results are presented for subgroups and for the target population as a whole.</p> <p>Results</p> <p>The impact of the use of the ACCG scenario in subgroups (aged 40–80) without concomitant cardiovascular and related diseases is mainly positive. Generally, costs and life-years decrease in unison in the lowest blood pressure group, while in the highest blood pressure group costs and life-years increase together and in the other groups the ACCG scenario is less expensive and produces more life-years. When the costs and effects for subgroups are combined using standard decision analytic aggregation methods, the ACCG scenario is cost-saving and more effective.</p> <p>Conclusion</p> <p>The ACCG scenario is likely to reduce costs and increase life-years compared to the PCP scenario in many subgroups. If the estimated trade-offs between the subgroups in terms of outcomes and costs are acceptable to decision-makers, then widespread implementation of the ACCG scenario is expected to reduce overall costs and be accompanied by positive outcomes overall.</p
