The successful first edition of HACCP: A Practical Approach has established itself as the definitive text on HACCP for the food industry. In an easy-to-read style, it gives a step-by-step approach to developing an effective HACCP system. In this new edition authors bring us up to date with current thinking, including the use of more modular HACCP systems and even generic HACCP in some sectors. Greater attention is paid to planning and implementation, and the theory is illustrated with a completely new set of case studies from UK, Ireland, USA, Canada, South America and Asia. It is an invaluable text for everyone who needs to know what HACCP really is, what it can do for a food business, and the best way to build an effective system.
