Download or read book Mycotoxin Control in Low and Middle Income Countries written by Christopher P. Wild and published by IARC Working Group Report. This book was released on 2016-02-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an evaluation of measures to reduce exposure to highly toxic and carcinogenic contaminants in staple diets in Africa as well as parts of Asia and Latin America. Many of the poorest people in these regions are exposed to the pervasive natural toxins, aflatoxins and fumonisins, on a daily basis by eating their staple diet of groundnuts, maize, and other cereals. Exposure to mycotoxins at these high levels substantially increases mortality and morbidity. Aflatoxins are a cause of human liver cancer, and fatalities from acute aflatoxin poisoning outbreaks occur in Africa and Asia. The International Agency for Research on Cancer convened a Working Group of world-leading experts to review the health effects of aflatoxins and fumonisins and to evaluate intervention measures. The panel concluded that these mycotoxins not only are a cause of acute poisoning and cancer but also are a likely contributor to the high levels of stunting in children in affected populations. The Working Group also identified effective measures to reduce exposure in developing countries. The panel evaluated 15 interventions, considering the strength of the evidence as well as its completeness and its transferability at an individual, community, or national level. Four of the interventions were judged to be ready for implementation: improvement of dietary diversity; crop sorting; post-harvest measures, including improved storage; and, in Latin America for maize, optimized nixtamalization. These recommendations would be relevant for investment of public, nongovernmental organization, and private funds at the scale of the subsistence farmer, the smallholder, and through to a more advanced value chain.
Download or read book Aflatoxins written by Unnevehr, Laurian and published by Intl Food Policy Res Inst. This book was released on 2013-09-30 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aflatoxins are a naturally occurring carcinogenic byproduct of common fungi on grains and other crops, particularly maize and groundnuts. They pose a significant public health risk in many tropical developing countries and are also a barrier to the growth of domestic and international commercial markets for food and feed. In recent years the aflatoxin problem has garnered greatly increased attention from both policy and donor communities around the globe. What can be done to reduce the detrimental impacts of aflatoxins? Because growth of the molds that produce aflatoxins is caused by multiple factors, and because they must be controlled along the entire value chain from production to consumption, only a robust multifaceted approach to controlling aflatoxins is likely to be effective. The nineteen briefs in this set thus provide different perspectives on aflatoxin risks and solutions. The analyses fall under four broad themes: (1) what is known about the health risks from aflatoxins; (2) how to overcome market constraints to improved aflatoxin control by building new market channels and incentives; (3) what is the international policy context for taking action in developing countries; and (4) what is the state of research on new aflatoxin control technologies, including new methods for aflatoxin detection, crop breeding, biological control, food storage and handling, and postharvest mitigation. These briefs collectively provide a much clearer picture of the state of current efforts at combatting aflatoxins. They also identify what gaps loom particularly largeincluding the need for contry-specific risk analysis and for testing integrated solutions for the entire supply chainin our global efforts to effectively reduce human exposure to aflatoxins and increase the economic returns to smallholders in agriculture.
Download or read book Technologies and strategies for aflatoxin control in Kenya A synthesis of emerging evidence written by Hoffmann, Vivian and published by Intl Food Policy Res Inst. This book was released on 2020-01-21 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aflatoxin is a poisonous substance produced by a fungus, Aspergillus flavus, that occurs naturally in soils of cultivated and non-cultivated areas. The fungus commonly produces the toxin in maize, groundnut, and other staple grains and vegetables, and is especially prevalent in Africa. When animals consume feed contaminated with aflatoxin, milk and (at very low levels) meat, fish and eggs, can also be contam-inated. This note brings together recent research from the CGIAR and others on technologies for aflatoxin control in Africa and provides recommendations for catalyzing their adoption.

This book was released on 2003-09-29 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints. Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safetyâ€"including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Download or read book Aflatoxins in Food written by Khalid Rehman Hakeem and published by Springer Nature. This book was released on 2022-01-13 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins are the metabolites of fungus and are reported to contaminate nearly 25% of the food produced worldwide. The mycotoxins of most significance are the aflatoxins due to their severe health implications and their prevalence in food commodities on a larger scale. Aflatoxins are produced by certain species of fungi the most prominent among which are Aspergillus flavus, A. parasiticus and A. nominous. Food commodities of African and South Asian countries are especially reported to have aflatoxins well beyond the allowable limits but due to the global trade of food commodities developed countries are also prone towards the perils of aflatoxins. Moreover, climate changes may have a substantial impact on the distribution and global prevalence of aflatoxins in the near future. The International Agency for Research on Cancer (IARC) has classified the aflatoxins as group 1 category carcinogen. Aflatoxins are also reported as teratogenic, mutagenic, growth retardant, immunosuppressant and may also cause nervous system and reproductive system disorders. Preventive approaches involving good manufacturing from “farm to fork” are the major focus of the current food industry. The aim of our book is to provide readers with the most recent data and up-to-date studies from aflatoxins research, with specific focuses on (i) the impact of aflatoxins on human health, (ii) new approaches by the researchers from different parts of the world to degrade aflatoxins and (iii) potential preventive approaches that can significantly lessen the burden of aflatoxins in food products
Download or read book Observability of food safety losses in maize Evidence from Kenya written by Hoffmann, Vivian and published by Intl Food Policy Res Inst. This book was released on 2019-12-06 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike physical losses, deterioration of food safety can be difficult to observe. In low- and middle- income countries, much of the food supply is never tested for safety hazards. We analyze data from 1500 maize samples and associated consumer surveys collected from clients of small-scale hammer mills in rural Kenya. We find that while visible damage to maize is penalized by lower prices, there is no correlation between price and aflatoxin, a carcinogenic fungal contaminant, implying an absence of market incentives to manage this aspect of food loss. Aflatoxin contamination is, however, correlated with consumer perceptions of quality, especially for self-produced maize, suggesting an information asymmetry that could lead to inefficiencies in this market.
Download or read book Aflatoxin written by Lukman Abdulra'Uf and published by BoD – Books on Demand. This book was released on 2017-08-30 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aflatoxins are a group of highly toxic and carcinogenic substances, which occur naturally, and can be found in food substances. Aflatoxins are secondary metabolites of certain strains of the fungi Aspergillus flavus and A. parasiticus and the less common A. nomius. Aflatoxins B1, B2, G1, and G2 are the most important members, which can be categorized into two groups according to the chemical structure. As a result of the adverse health effects of mycotoxins, their levels have been strictly regulated especially in food and feed samples. Therefore, their accurate identification and determination remain a Herculean task due to their presence in complex food matrices. The great public concern and the strict legislation incited the development of reliable, specific, selective, and sensitive analytical methods for pesticide monitoring that are discussed in this book.

Download or read book Achieving a nutrition revolution for Africa written by Hendriks, Sheryl L. and published by Intl Food Policy Res Inst. This book was released on 2016-10-17 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing the 2015 Annual Trends and Outlook Report (ATOR) on nutrition will contribute to a broader understanding of the critical role of nutrition in achieving international, continental, and national economic growth targets through agriculture, food security, and nutrition. This report presents information and analysis in support of evidence-based policy making that should inform the second generation of CAADP national investment plans now being developed. This is an important moment for shaping the region’s future and ensuring that the much-needed agriculture-led growth and development agenda can simultaneously deliver on improving nutrition, saving lives, improving productivity and health, and curbing nutrition-related diseases and the associated public health expenditures. These investment plans should address not only the usual elements of undernutrition but also widespread micronutrient deficiencies (termed “hidden hunger”) and the growing problem of overweight and obesity that is associated with economic growth.
Download or read book Improving Public Health Through Mycotoxin Control written by International Agency for Research on Cancer and published by IARC Scientific Publications. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins are fungal toxins that contaminate many of the most frequently consumed foods and feeds worldwide, including staple foods consumed by many of the poorest and most vulnerable populations in the world. Therefore, human and animal exposure to one or more of this broad group of toxins is widespread. Mycotoxins have the potential to contribute to a diversity of adverse health effects in humans, including cancer, even at low concentrations. Economic burdens resulting from crop contamination are added to those on health. Given the ubiquitous nature of exposure in many countries, an urgent need exists for a coordinated international response to the problem of mycotoxin contamination of food. This book aims to sensitize the international community to the mycotoxin problem in a format that is accessible to a wide audience and is useful to decision-makers across a broad spectrum of disciplines, including agriculture, public health, marketing, and economics. The editors hope that this book will be a stimulus to governments, nongovernmental and international organizations, and the private sector to initiate measures designed to minimize mycotoxin exposure in high-risk populations. The book not only provides a scientific description of the occurrence and effects of mycotoxins but also goes further by outlining approaches to reduce mycotoxin exposure aimed at improving public health in low-income countries.
