Most of the non-nutrient chemicals humans ingest with their normal diet are naturally occurring secondary metabolites of food plants. Quantitatively, exposures to these plant-specific constituents may significantly exceed dietary exposures to most of the synthetic chemicals, which may intentionally or unintentionally occur in food. Some of them have been shown to be highly potent toxins. It has been proposed to define inherent plant toxicants as plant constituents, which might induce adverse effects in humans when the plant or plant products are consumed. Examples are glycoalkaloids in potatoes, cyanogenic glucosides in cassava or phytohemaglutinin in red kidney beans. They have all been causally associated with acute human toxicity when ingested through foods that were not properly processed or prepared. Both toxicological and exposure data are limited for most inherent plant toxicants. Therefore, accurate risk assessment is often not possible. For many inherent toxicants the margin of exposure between toxic levels in humans and actual exposure from food is low. Therefore risk management measures need to be implemented in order to ensure food safety. Management options include development of cultivars low in inherent toxicants, agricultural and storage practices, and food processing. Further work is necessary to better characterize the potential health impact of inherent plant toxicants. This should include the development of a risk assessment paradigm which considers both potential adverse but also beneficial effects of secondary plant metabolites and of the pertinent food plants as such.

The prevalence of naturally occurring toxins in plant and animal foods represents one of the most significant food safety issues, drawing the attention of both scientists and regulators alike. This unexplored area related to food quality is indeed a big concern for consumers, various regulatory authorities, and food industries. Apart from essential nutrients, several food crops are capable of producing a vast array of nonnutritious secondary metabolic products. These toxins produced as secondary metabolites have the potential to exhibit both beneficial and deleterious effects in both human beings and animals. Nevertheless, there has been huge progress in agricultural practices and food processing technologies, but still the number of nonnutritive substances and naturally derived toxins persist in our diet. Handbook of Plant and Animal Toxins in Food: Occurrence, Toxicity, and Prevention, focuses on various selected toxins in foods derived from plants as well as animals. The prominent plant toxins include solanine and chaconine, mushroom toxins, phytates, tannins, oxalates, goitrogens, gossypol, phytohemagglutinins, erucic acid, saponins, cyanogenic glycosides, enzyme inhibitors, BOAA (lathyrogens), toxic amino acids and toxic fatty acids. The prominent animal toxins covered in the book include various seafood toxins, shellfish toxins and biogenic amines. Key Features: Presents complete information about a plethora of toxins Provides quick and easy access to data on major plant and animal toxins Covers distribution of toxins in the plant and animal kingdom Provides comprehensive information on chemistry, safety and precautions of each toxin Commencing with a brief introduction of food toxins, this book is designed in such a way that the readers will be introduced to toxicity, safety and occurrence of each toxin selected. It also discusses the in-depth detailed information on food poisoning and its prevention. The book will also shed light on foodborne illness associated with toxins. The primary audience for this work will be food scientists, food toxicologists, university scholars and college students. Furthermore, the book will be of immense help for public health officials, pharmacologists, and food safety officers who are involved with enforcing regulations meant to ensure the safety of a particular food

Natural toxins are toxic compounds that are naturally produced by living organisms. These toxins are not harmful to the organisms themselves, but they may be toxic to other creatures, including humans, when eaten. These chemical compounds have diverse structures and differ in biological function and toxicity. Some toxins are produced by plants as a natural defense mechanism against predators, insects, or microorganisms, or as a consequence of infestation with microorganisms, such as mold, in response to climate stress (such as drought or extreme humidity). Well-known groups of natural toxins of plant origin are: cyanogenic glycosides, pyrrolizidine alkaloids, furocoumarins, lectins, and glycoalkaloids. These plant-origin natural toxins can cause a variety of adverse health effects and pose a serious health threat to both humans and livestock. Analysis of Naturally Occurring Food Toxins of Plant Origin is divided into three sections that provide a detailed overview of different classes of food toxins that are naturally found in plants, including various analytical techniques used for their structural characterization, identification, detection, and quantification. This book provides in-depth information and comprehensive discussion over quantitative and qualitative analysis of natural toxins in plant-based foods. Key Features: • Provides a detailed overview of different classes of natural toxins found in plants. • Explains how IR, NMR, and mass spectrometry are utilized in characterization and identification. • Describes applicability of HPLC, LC-MS, GC-MS, and HPTLC techniques for detection and quantification. • Discusses progress in the field related to capillary electrophoresis, ELISA, and biosensors for quantitative application of these techniques.
