Download or read book Mycotoxins Occurence in Feed and Their Influence on Animal Health written by Maciej Gajęcki and published by MDPI. This book was released on 2021-01-15 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the presented studies, the health condition of animals in rearing and breeding should be regularly monitored. This would allow early detection of delicate deviations in the body of clinically healthy individuals. Unfortunately, regular monitoring of the health of animals in commercial production is not performed. It follows that this type of research should be an introduction to further, more inquisitive steps. This can form the basis for further courses of action, indicating which organs or tissues field doctors or researchers should be interested in and what to pay attention to in order to find the correct answer, concerning the situation in the animal body. In the future, we should determine biomedical markers for use in precision veterinary medicine. In human medicine, this has been practiced with great success. The problem, however, is that we are getting to know more and more substances produced by mold fungi. This causes a build-up of new interpretative problems, causing health conditions (diagnosis), as well as analytical problems. To fully understand the results we need new techniques to assess toxicological and chemical hazards, including those related to undesirable substances. We need a solid knowledge of the biological pathways underlying the toxicity and tolerance to interference factors toxicological processes. We hope that the presented study will allow for a better understanding of mycotoxicoses that bother us and our animals, which will allow for more effective preventive actions.

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 Mycotoxins written by P Tensingh Gnanaraj and published by New India Publishing Agency. This book was released on 2021-05-18 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal protein sources such as meat, egg and milk are complete proteins as they provide all essential amino acids in highest quality. To provide high quality protein to humans, livestock have to be fed with toxin free quality feedstuffs. Animal feed plays a major role in the global food industry, as it has highest returns to the producer throughout the world. Animal feeds are produced either by livestock farmers themselves locally or feed manufacturing companies. Feeds produced have to be secured and stored in a proper manner to avoid microbial as well as any other biotic agents. Mycotoxins are such naturally occurring toxin produced by the fungal growth. The molds can grow in any of the feed stuffs like maize, other cereals, Groundnut cake and other oil cakes in warm humid climatic conditions. Mycotoxins can have variety of serious health hazards ranging from mild irritation to deadly cancers in livestock and humans. Addressing the issues related to mycotoxin is the need of the hour. With globalisation of the feed industry and rapid climatic changes, it is very difficult to enumerate the occurrence and presence of the toxin in the feedstuff. These unnoticeable toxin effects may have direct and indirect impact on animal production system. It is very essential to have adequate knowledge about the metabolism, growth and reproduction of various mycotoxins and the toxicological properties of their intermediate products produced during metabolism to neutralize these toxins.

Download or read book The Mycotoxin Blue Book written by Duarte Diaz and published by Context Products. This book was released on 2005-01-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Moulds and the mycotoxins they produce, have a wide-ranging economic impact on animal agriculture on every continent of the globe. Mould growth robs feed nutritive value and reduces intake, which lowers efficiency. Mycotoxins, even when present at levels previously considered 'trace', have negative effects on performance and health, particularly in the context of today's more highly productive modern livestock genetics. Food-borne toxins also threaten human health through contaminated cereal and protein sources and transfer of toxins in food animal products. The Mycotoxin Blue Book focuses on the physiological effects and field occurrence of mycotoxins. Detailed information on types of moulds and mycotoxins and the conditions under which moulds flourish is included. Implications of mycotoxin contamination of feedstuffs for all major food animal species are presented in addition to aquaculture and companion animals. Sampling and analytical issues are covered in depth; as is the topic of mycotoxins in human foods. Finally, practical means of ameliorating mycotoxin effects are addressed. It is the hope of the editor and authors that the material herein will lead to clearer recognition of mycotoxin problems and ultimately to ways of reducing their impact on food animal production. An excellent guide for nutritionists, advisors, farmers and students involved with and using animal feed. Contents: Sampling feeds for mycotoxin analysis Mycotoxins: their effects in poultry and some practical solutions Effects of mycotoxins in horses Effects of mycotoxins on domestic pet species Effects of mycotoxins on antioxidant status and immunity Mycotoxins in aquaculture Principles and applications of mycotoxin analysis Mycotoxins in the human food chain Mould growth and mycotoxin production Current concepts in mycotoxicoses in swine Mycotoxins in forages Mycotoxin interactions Mycotoxins: metabolism, mechanisms and biochemical markers Effects of mycotoxins in ruminants Mycotoxin sequestering agents: practical tools for the neutralisation of mycotoxins Index

Download or read book Mycotoxins in Food and Beverages written by Didier Montet and published by CRC Press. This book was released on 2021-06-11 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins are secondary metabolites produced by fungi in a wide range of foods (cereals, peanut, tree nuts, dried fruits, coffee, cocoa, grapes, spices...) both in the field and after harvest, particularly during storage. They can also be found in processed foods of plant origin, or by transfer, in food products of animal (milk, eggs, meat and offal). Mycotoxins are of major concern since they can cause acute or chronic intoxications in both humans and animals which are sometimes fatal. Many countries, particularly in Europe, have set maximum acceptable levels for mycotoxins in food and feed. The book reviews the latest literature and innovations on important aspects of mycotoxins, e.g. mycotoxin producing fungi and the related ecosystems, mycotoxin occurrence, toxicity, analysis and management. Quantitative estimations of impacts of climate change on mycotoxin occurrence have been made recently, using predictive modelling. There is also a growing interest in the occurrence and toxicity of multiple mycotoxins in food and feed, including emerging or modified forms of mycotoxins. Innovative tools were also developed to detect and quantify toxinogenic fungi and their toxins. In order to reduce the use of chemicals that are harmful to the environment and health of consumers, alternative methods of prevention and decontamination of mycotoxins were tested in pre- and post-harvest, using microorganisms, natural substances or radiation treatments.

This book was released on 2020-02-11 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2019 in the subject Veterinary medicine, grade: 18, course: Seminar on Animal Health, language: English, abstract: Mycotoxins are secondary metabolism of filamentous fungi, which under suitable temperature and humidity conditions, and found in various foods and feeds, causing negative effect for human and animal health.There are different mycotoxins which have agricultural and economic importance including aflatoxins, ochratoxins, trichothecenes, zearalenone, fumonisins, tremorgenic toxins, and ergot alkaloids. Mycotoxins occur more frequently in areas with a hot and humid climate, favourable for the growth of molds, they can also be found in temperate zones.In comparison to monogastric species, ruminant animals are generally less susceptible to the adverse effects caused by contamination of feeds with mycotoxins because presence of rumen microflora in rumen. However, a number of mycotoxins resist rumen degradation, causing distinct clinical signs of intoxication. Dairy cattle can be exposed to different number of mycotoxins because complex feeding diet originating from different feed materials such as roughage and concentrates. Exposure of diary catte to these mycotoxins may result in unexpected health problem. Due to apre-existing negative energy balance, cows in the transition period are considered to be particularly sensitive to the exposure to feeds. The variation of mycotoxinoccurence due to different factors, including agricultural practices and climatic conditions. Aflatoxins (AFs) are found in maize and peanuts, aswell as in tree nuts and dried fruits. OTA is found mainly in cereals, but significant levels of contamination may also occur in wine, coffee, spices and dried fruits. Other products of concern are beans, roasted coffee and cocoa, malt and beer, bread and bakery products, wines and grape juices, spices, poultry meat and kidneys, pig kidneys and pork sausages. The production of secondary metabolism is the effect
Download or read book Mycotoxin Contamination Management Tools and Efficient Strategies in Feed Industry written by Federica Cheli and published by . This book was released on 2020 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins represent a significant issue for the feed industry and the safety of the feed supply chain, with an impact on human health, animal health and production, economies, and international trade. The globalization of the trade in agricultural commodities and the lack of legislative harmonization have contributed significantly to the discussion about the awareness of mycotoxins entering the feed/food supply chain. The feed industry is a sustainable outlet for food processing industries, converting byproducts into high-quality animal feed. Mycotoxin occurrence in food byproducts from different technological processes is a worldwide topic of interest for the feed industry, aiming to increase the marketability and acceptance of these products as feed ingredients and include them safely in the feed supply chain. Since mycotoxin contamination cannot be completely prevented pre- or post-harvest, the modern feed industry needs new tools for monitoring and managing the risk of mycotoxins and strategies to prevent and reduce mycotoxins in compound feed manufacturing. The aim of this Special Issue book was to bring together a collection of valuable articles with innovative ideas for a sustainable and competitive feed industry.

Download or read book Mycotoxins and Food Safety written by Jonathan W. DeVries and published by Springer Science & Business Media. This book was released on 2002-03-31 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins, from the Greek "mukes" referring to fungi or slime molds and toxin from the Latin "toxicum" referencing a poison for arrows, have earned their reputation for being potentially deleterious to the health and well being of a consuming organism, whether it be animal or human. Unfortunately, mycotoxins are a ubiquitous factor in the natural life cycle of food producing plants. As such, control of the potential impact of mycotoxins on food safety relies heavily upon accurate analysis and surveys followed by commodity segregation and restricted use or decontamination through processing. The purpose of this book is to provide the most comprehensive and current information on the topic of mycotoxins and assuring food safety. Chapters represented in the book reflect such diverse topics ranging from occurrence and impact, analysis, reduction through processing and plant breeding, toxicology and safety assessments to regulatory perspectives. Authors represent a range of international perspectives.

Download or read book Mycotoxin Exposure and Related Diseases written by Susana Viegas and published by MDPI. This book was released on 2020-05-12 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins are considered the most frequently occurring natural contaminants in human and animal diets. Considering their potential toxic and carcinogenic effects, mycotoxin exposure assessment has particular importance in the context of health risk assessment. The magnitude of a given exposure allows the derivation of the associated risk and the potential for the establishment of a disease. Although food ingestion is considered a major route of human exposure to mycotoxins, other contexts may also result in exposure, such as specific occupational environments where exposure to organic dust also occurs due to the handling of organic materials. Animals could be exposed to mycotoxins through consumption of contaminated feed, subsequently entering in the food chain and thus constituting a source of exposure to humans. Human biomonitoring is considered a new frontier for the establishment of the human internal exposure to mycotoxins. Although several studies have summarized the potential outcomes associated with mycotoxin exposure, major gaps in data remain in recognizing the mycotoxins that are the cause of diseases. This book contributes provides research that supports the anticipation of potential consequences of the exposure of humans and animals to mycotoxins, future risk assessments, and the establishment of preventive measures.
