Military Trail, 240-SZG Boca Raton, FL 33431 [email protected] Printed in Canada 3 PREFACE Educating the veterinary profession about Foreign Animal Diseases has been a long tradition of the U. S. Animal Health Association. The first “Gray Book” edition was published more than half a century ago in 1953, with subsequent editions in 1964, 1975, 1984, 1992 and in 1998. Traditionally, the task of the reviewing and updating this book, still familiarly known as the “Gray Book” (despite the white cover of recent editions) falls to the Chair and Co-Chair of the USAHA’s Foreign and Emerging Disease Committee. We are thus indebted to the U.S. Animal Health Association for the opportunity to assemble this, the 7 th edition of Foreign Animal Diseases . There have been vast changes in the world since the last edition was published in 1998. At that time, the World Trade Organization was just three years old and only beginning the tremendous facilitation of international trade that we see today. The last edition was published before Nipah virus in Malaysia, before the massive foot-and-mouth disease outbreak in the United Kingdom, before the advent of the term “agroterror”, before SARS had infected any humans, and prior to the possibility of highly pathogenic avian influenza as a human pandemic. Indeed, with so many new pathogens as well as old pathogens surfacing in new and unexpected places, the term “foreign animal disease” is becoming less relevant, even as the threat of foreign animal disease incursions becomes more relevant. We have utmost respect for and gratitude to the authors of the chapters. Their contributions were timely, articulate, and accurate. This book is rightfully theirs and we are merely organizers and purveyors of their information. We owe special thanks to Visual Information Services at the Plum Island Animal Disease Center, whose staff supplied most of the new photographs in Part IV. In addition, the Animal and Plant Health Inspection Service, Professional Development Staff (PDS), was very generous in allowing us to borrow Dr. Jason Baldwin, who served as an infallible and incredibly diligent copy and content editor. PDS also supplied the funding for the final formatting of the book, including the new cover design. We also acknowledge our host institutions, the Colleges of Veterinary Medicine at the University of Georgia and Cornell University, for allowing us the time to devote to the editing and assembling of this book. We were each generously 4 given the opportunities to apply our efforts, without any expectations of compensation. Fortunately, the leaders of our respective institutions understand the importance and impact that this volume has on preparing our animal health professionals. Lastly, we wish to recognize the long-term efforts of Dr. Charles Mebus, in research, diagnosis, and dissemination of information regarding foreign animal diseases. Chuck Mebus has been a mentor to the two of us at various stages in our careers and has always served as a stellar role model, good friend, and a visionary regarding the larger picture of animal health. As it was done for the 6 th edition, we re-dedicate this, the 7 th edition of Foreign Animal Disease, to him.

The preparation of this book is a tangible example of the remarkable cooperation between all the sectors of the U.S. Animal Health Association. Professionals from academia, U.S. federal and state agencies, and a number of foreign countries have shared their expertise and their time to create this seventh edition. The Chair and Co-Chair of the USAHA Committee on Foreign and Emerging Diseases, Corrie Brown, DVM, PhD, and Alfonso Torres, DVM, PhD, respectively, have coordinated the compilation of this edition, with USAHA acting as the publishing agency. On behalf of the USDA, I want to express my appreciation to the leadership of USAHA, Drs. Brown and Torres, and all the authors, reviewers and editors for their selfless contributions. There are no monetary remunerations or royalties for writing this book: its creation grew from the collective understanding of the importance of sustaining a successful history of safeguarding all animal health industries from animal diseases.
