The contributions in this volume were first presented at a symposium organized by the editors and held at the 214th National Meeting of the American Chemical Society in Las Vegas in September, 1997. The symposium was sponsored by the ACS Division of Agricultural and Food Chemistry and covered recent developments of interest in food analysis. Many changes have occurred since the standard textbooks on food analysis were published: E. coli 0 157: H7 has leaped into prominence, requiring new and rapid methods of detection; MALDI-MS was developed and used in food analysis for the first time; elec tron microscopy, fluorescence spectroscopy, and electrorheology have been applied to cheese, bread, meat, and chocolate, new methods for monitoring and predicting shelf life have been introduced; new techniques for determining the composition of food have evolved. This book includes many emerging approaches which food scientists may find useful and probably will not find in a textbook. The editors thank the authors whose work is presented in these chapters, the Divi sion of Agricultural and Food Chemistry for agreeing to hold the symposium, and our edi tors at Kluwer Academic I Plenum Publishers whose assistance made our task easier.

"Overall, Drs Acuff and Dickson have produced a truly international and model reference here; it reflects robust research-based knowledge and best practices across the entire supply chain of the beef industry. Authors reflect international expertise, and the topics are well-organized and germane to beef's role in public health. Each author has compiled a very comprehensive discussion of their respective topics; but each chapter is ultimately comprehensible on food safety issues for even the less-knowledgeable reader. The text reflects the thoughts and knowledge of some of the best food safety minds in the business... all-in-all, a great read!" Meat Science Beef production faces a range of challenges. There is an ongoing need to ensure safety in the face of threats from zoonoses and other contaminants, particularly in more intensive beef production systems and with more complex supply chains (allowing potentially broader transmission). At the same time, consumers have ever higher expectations of sensory and nutritional quality. Drawing on an international range of expertise, this book reviews research addressing safety challenges in beef production. The first part of the book addresses pathogenic risks on the farm, developments in detection techniques and safety management. The second part of the book reviews safety issues in the rest of the supply chain, from slaughterhouse operations to management of the cold chain and consumer handling of fresh beef. Ensuring safety and quality in the production of beef Volume 1: Safety will be a standard reference for animal and food scientists in universities, government and other research centres and companies involved in beef production. It is accompanied by Volume 2 which reviews quality issues in beef production.

Foodborne pathogens continue to cause major public health problems worldwide. These organisms are the leading causes of illness and death in less developed countries, killing approximately 1.8 million people annually. In developed countries, foodborne pathogens are responsible for millions of cases of infectious gastrointestinal diseases each year, costing billions of dollars in medical care and lost productivity. In addition, new foodborne diseases are likely to emerge driven by factors such as pathogen evolution, changes in agricultural and food manufacturing practices, and changes to the human host status. A third problem is that there are growing concerns that terrorists could use pathogens to contaminate food and water supplies in attempts to incapacitate thousands of people and disrupt economic growth. Fuelled by these concerns, research into the genomics, molecular biology, and microbiology of the most important foodborne pathogens has escalated to unprecedented levels in recent
