Ochratoxin A and Aflatoxin B1: New Research first presents the latest knowledge regarding the occurrence of ochratoxin A in dry-cured meat and dairy products, as well as relevant food safety issues. Different remediation strategies such as heating, ripening, drying, storage and the use of microbial cultures, which have been adopted for the prevention or decontamination of ochratoxin A, are critically reviewed.Next, the authors assess the occurrence of ochratoxin A in different types of dry-fermented sausages and hams produced by various households in Croatia, proposing that in order to avoid contamination, the production of household-based meat and meat products should run under standardized and well-controlled conditions.In the subsequent study, a total of sixty mold-contaminated rice, corn and groundnut samples were collected from one of the Cauvery delta regions of Tamil Nadu, India, and analyzed to determine the co-occurrence of ochratoxin A and citrinin, and the respective mycotoxigenic fungal strains that produce these toxins.Besides the known adverse effects of alcohol, beer could also be the source of several mycotoxins such as aflatoxin B1. Aflatoxin B1 is the most toxic among the identified aflatoxins and classified into group I as a human carcinogen by the International Agency for Research on Cancers. The stability of aflatoxin B1 during the brewing process, as well as the most important detection techniques and sample treatment used for the determination of this compound are evaluated.

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

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.

Mycotoxins are toxins produced by aerobic, microscopic fungus under special conditions of moisture and temperature. They colonize in a variety of foods from harvest to the grocer. Mycotoxins have gained world wide interest in recent years with the revelation of the effect of these toxins on health. A current example is the presence of ochratoxin A, a human carcinogen and nephrotoxin, in wines. The increased concern about fruit safety has led to increased studies throughout the world and enhanced awareness for stringent regulations governing mycotoxin limits in food. Presented in three defined sections, this is the first book to provide comprehensive analysis of the main mycotoxins contaminating fruits and vegetables and their derived products. The first section provides a safety evaluation of mycotoxins in fruits and vegetables, details regarding factors affecting mycotoxin production and diffusion in the fruit tissue, and recent methods for detection of mycotoxigenic fungi and mycotoxins produced by the fungi. The second part takes a critical look at the main individual mycotoxins and the third section focuses on approaches for prevention and control. * The first book dedicated to mycotoxins in fruits and vegetables * Presents mycological, mycotoxicological and phytopathological aspects of fruits and vegetables * Includes an analysis of detection, prevention and control methods for mycotoxigenic fungi and the mycotoxins they produce * Provides a complete risk assessment and safety evaluation of mycotoxins in perishable produce

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.
