This Book "Introductory Food Toxicology" aims to present concise and updated information relevant to the field of Food Toxicology. The book begins with a brief introduction to the vast field of "Toxicology" and then explains how the sub discipline of Food Toxicology is related to the main discipline. The book not only covers the core issues of Food Toxicology but also throws light on the recent challanges in the field and how newly developed fields of genomics and nano technology can be used to address these issues. Chapters dedicated to the impact of Genetically Modified Crops on the Food quality have also been incorporated. The book includes chapters dedicated to the topic of Food contaminants that get into the Food during processing and manufacturing stages. I hope the book shall be a good and handy resource material for the students, academicians and researchers in the field.
