Food contains nutritional substances that are necessary for the development, upkeep, and repair of body tissues as well as the control of vital processes. Therefore, it is essential to consume safe foods, which can be ensured by practicing food safety. The practice of preparing, handling, and storing food in such a way that minimizes the risk of individuals becoming ill from foodborne illnesses is called food safety. Issues related to food safety arise from pathogenic microorganisms such as bacteria, which cause food intoxication or poisoning. Toxicology is the scientific study of the harmful effects of chemicals on living organisms. It also involves diagnosing and treating conditions that occur as a result of exposure to toxins and toxicants. In the field of toxicology, the main focus remains on determining the safety of the food by carrying out a detailed research on the effects of toxins. This book explores all the important aspects of food safety and toxicology in the present day scenario. It consists of contributions made by international experts. The book will serve as a reference to a broad spectrum of readers.

Biogenic amines (BAs) are organic and nitrogenous compounds found in certain fermented foods, such as sausage, wine, cheese, fish and fermented vegetables. They are involved in controlling various functions of the brain such as emotions, blood pressure, movements, endocrine secretion, behavior and temperature. Bacterial decarboxylation of the amino acids in food leads to the production of BAs. The consumption of large amounts of BAs in food can have toxic effects and may also lead to gastrointestinal, neurological, respiratory and cardiovascular issues, as well as hypertensive, psychotropic and vasoactive effects. The regulation of decarboxylase activity of amino acids can help in controlling the concentrations of BAs in food items. Their levels can be decreased through various techniques including hydrostatic pressure, smoking, temperature, packing, irradiation, starter culture, oxidizing formed biogenic amine, additives, and pasteurization. This book explores all the important aspects of biogenic amines, including their occurrence and toxic effects in the present day scenario. It will also provide interesting topics for research, which interested readers can take up. This book is a resource guide for experts as well as students.
