Quantifying pre-consumer food and nutrient losses from the Australian lamb and sheep meat value chain: a case study

To achieve sustainable development, United Nation members have agreed to reduce food loss along the pre-consumer food supply chain. Food loss and waste is a significant challenge facing Australia and the world, with an estimated one third of all food produced locally being lost or wasted. Globally, Australia is the second largest producer of sheep meat and, locally in Australia sheep meat is the second largest meat industry. Previous assessments of Australian livestock industries estimate low levels of food product losses from the sheep meat chain. This case study aimed to quantify nutrient losses at the point of slaughter of Australian lambs and sheep, using a mass balance approach with secondary data. The results from this study align with this previous assessment with respect to the level of products and nutrients downgraded at the point of slaughter, except for the impact of cadmium contamination on adult sheep liver and kidney downgrades. In turn, cadmium contamination emerged as a key contributor to micronutrient losses, notably dietary folate equivalents, and vitamin A retinol equivalents (RE). There was moderate to high uncertainty in the outputs of the assessment, predominantly due to the absence of data. Addressing these challenges, particularly the absence of offal production data, is crucial as it influences the overall accuracy of the results. This study identifies areas for improvement in the Australian sheep meat value chain, including data governance, at both the macro and micro levels. It also serves as a foundational step in understanding how reducing food and nutrient losses in the Australian sheep meat value chain could contribute to food security and nutrition goals

Characterising infant and young child feeding practices and the consumption of poultry products in rural Tanzania: A mixed methods approach

Suboptimal breastfeeding practices, early initiation of complementary feeding, and monotonous cereal‐based diets have been implicated as contributors to continuing high rates of child undernutrition in sub‐Saharan Africa. Nutrition‐sensitive interventions, including agricultural programs that increase access to nutrient‐rich vegetables, legumes, and animal‐source foods, have the potential to achieve sustainable improvements in children's diets. In the quest to evaluate the efficacy of such programs in improving growth and development in the first 2 years of life, there is a role for mixed methods research to better understand existing infant and young child feeding practices. This analysis forms part of a longitudinal study assessing the impact of improvements to poultry health and crop production on diets and growth of 503 randomly selected children from eight rural communities in Manyoni District in central Tanzania. Using an explanatory sequential design, the quantitative phase of data collection was conducted between May 2014 and May 2016, comprising six monthly structured questionnaires, four monthly household‐level documentation of chicken and egg consumption, and fortnightly records of children's breastfeeding status. The subsequent qualitative phase involved in‐depth interviews with a subset of 39 mothers in October 2016. Breastfeeding was almost universal (96.8%) and of long duration (mean = 21.7 months, SD = 3.6), but early initiation of complementary feeding was also common (74.4%; mean = 4.0 months, SD = 1.8), overwhelmingly driven by maternal perceptions of insufficient milk supply (95.0%). Chicken and eggs were infrequently eaten, but close associations between maternal and child consumption patterns (p < .001) suggest the potential for strategies that increase household‐level consumption to bring nutritional benefits to young children

Food composition tables in resource-poor settings: Exploring current limitations and opportunities, with a focus on animal-source foods in sub-Saharan Africa

Animal-source foods (ASF) have the potential to enhance the nutritional adequacy of cereal-based diets in low- and middle-income countries, through the provision of high-quality protein and bioavailable micronutrients. The development of guidelines for including ASF in local diets requires an understanding of the nutrient content of available resources. This article reviews food composition tables (FCT) used in sub-Saharan Africa, examining the spectrum of ASF reported and exploring data sources for each reference. Compositional data are shown to be derived from a small number of existing data sets from analyses conducted largely in high-income nations, often many decades previously. There are limitations in using such values, which represent the products of intensively raised animals of commercial breeds, as a reference in resource-poor settings where indigenous breed livestock are commonly reared in low-input production systems, on mineral-deficient soils and not receiving nutritionally balanced feed. The FCT examined also revealed a lack of data on the full spectrum of ASF, including offal and wild foods, which correspond to local food preferences and represent valuable dietary resources in food-deficient settings. Using poultry products as an example, comparisons are made between compositional data from three high-income nations, and potential implications of differences in the published values for micronutrients of public health significance, including Fe, folate and vitamin A, are discussed. It is important that those working on nutritional interventions and on developing dietary recommendations for resource-poor settings understand the limitations of current food composition data and that opportunities to improve existing resources are more actively explored and supported

Adopting an intersectoral One Health approach in India: Time for One Health Committees

Following the several episodes of zoonotic disease outbreaks and the more recent COVID-19 pandemic, the Indian policy initiatives are committed to institutionalize One Health (OH) approaches and promote intersectoral, transdisciplinary collaboration and cooperation. The OH principle needs to be visualized beyond the scope of zoonoses. While conservation, ecological and veterinary professions are getting increasingly engaged with OH, most of the medical/clinical and social sciences professions are only peripherally aware of its nuances. The OH initiatives, by their essentially multidisciplinary nature, entail working across ministries and navigating tacit institutional hierarchies and allocating leadership roles. The logical operational step will be the constitution of One Health Committees (OHC) at the State and district levels. Here, we outline the key foundational principles of OHC and hope that the framework for implementation shall be deliberated through wider consultations and piloted and adopted in a phased mannerAuthors acknowledge the financial support received from UK Research and Innovation (UKRI) Global Challenges Research Fund (GCRF) One Health Poultry Hub (grant BB/SO11269/1)

Understanding the Impact of Historical Policy Legacies on Nutrition Policy Space:Economic Policy Agendas and Current Food Policy Paradigms in Ghana

Background The global food system is not delivering affordable, healthy, diverse diets, which are needed to address malnutrition in all its forms for sustainable development. This will require policy change across the economic sectors that govern food systems, including agriculture, trade, finance, commerce and industry – a goal that has been beset by political challenges. These sectors have been strongly influenced by entrenched policy agendas and paradigms supported by influential global actors such as the World Bank and International Monetary Fund (IMF). Methods This study draws on the concept of path dependency to examine how historical economic policy agendas and paradigms have influenced current food and nutrition policy and politics in Ghana. Qualitative data were collected through interviews with 29 relevant policy actors, and documentary data were collected from current policies, academic and grey literature, historical budget statements and World Bank Group Archives (1950-present). Results Despite increased political priority for nutrition in Ghana, its integration into food policy remains limited. Food policy agendas are strongly focused on production, employment and economic returns, and existing market-based incentives do not support a nutrition-sensitive food supply. This policy focus appears to be rooted in a liberal economic approach to food policy arising from structural adjustment in the 1980s and trade liberalization in the 1990s, combined with historical experience of ‘failure’ of food policy intervention and an entrenched narrowly economic conception of food security. Conclusion This study suggests that attention to policy paradigms, in addition to specific points of policy change, will be essential for improving the outcomes of food systems for nutrition. An historical perspective can provide food and health policy-makers with insights to foster the revisioning of food policy to address multiple national policy objectives, including nutrition

Aflatoxin and Mycotoxin Analysis: An Overview Including Options for Resource-limited Settings

Aflatoxins are fungal toxins of serious human health concern, more so in some developing countries where significant contamination of staple foods occurs and the prevalence of aflatoxin-related health effects is high. A plethora of techniques for food mycotoxin testing has been developed. Modern chromatographic techniques allow quantitative determination with high accuracy and sensitivity, but are expensive and difficult to operate and maintain. Rapid tests provide a cheaper alternative for screening large numbers of samples, although they need validation on all food matrices that are tested. One important aspect of tackling aflatoxin contamination and exposure is to ensure the availability of suitable methods for detection and quantification that are rapid, sensitive, accurate, robust, and cost-effective for food surveillance in resource-limited settings
