Microbiological risk assessment (MRA) is one of the most important recent developments in improving food safety management. Edited by two leading authorities in the field, and with a distinguished international team of experts, this book reviews the key stages and issues in MRA.

The book begins by placing MRA within the broader context of the evolution of international food safety standards

Part 1 introduces the key steps in MRA methodology. A series of chapters discusses each step, starting with hazard identification and characterisation before going on to consider exposure assessment and risk characterisation. Given its importance, risk communication is also covered.

Part 2 then considers how MRA can be implemented in practice. There are chapters on implementing the results of a microbiological risk assessment and on the qualitative and quantitative tools available in carrying out a MRA. It also discusses the relationship of MRA to the use of microbiological criteria and another key tool in food safety management, Hazard Analysis and Critical Control Point (HACCP) systems.

With its authoritative coverage of both principles and key issues in implementation, Microbiological risk assessment in food processing is a standard work on one of the most important aspects of food safety management.
