Chapter 8 **Contaminants in Animal Products 129**

**VI** Contents

Livestock production has played a key role in the development of human civilization. There has been a great increase in the consumption of animal products. Development of animalrearing techniques has steadily increased the productivity. The intention of agricultural ac‐ tivities planned by governments, food industry, producers, and consumers is to provide safety and adequate food by respecting the environment. Although many questions are be‐ ing raised about the sustainability of the world's food-animal agricultural resources. We be‐ gin to understand the detrimental effects conventional agriculture can have on local and global environments, with more studies focusing on alternative agriculture studies that compare alternative practices to conventional ones.

It is a pleasure to introduce on behalf of all authors the *Livestock Science* book. This book does not pretend to be fully comprehensive, but we believe it does provide topics which are of central importance. We hope this book will stimulate discussion about sustainable live‐ stock production that meets the long- and short-term goals of human food production. This book presents some in-depth reviews of selected topics in livestock science written by ex‐ perts in their respective areas. This book is divided into eight chapters, consisting of topics in food-animal production systems, management of several animal products, health-threat‐ en example by ticks in animals, and contaminants that may be found in animal foods.

We expect that the *Livestock Science* book will be of interest to a wide readership. We hope that a wide variety of scientists, researchers, and students may benefit from this book. We also recommend it to the general reader, who will find much of interest in these chapters.
