Foreword

I regard it an honour and privilege to have been asked to provide a preface for this significant monograph which surveys the recent and current developments in monitoring food toxins and toxicants which compromise human food safety. In the past, many incidents have caused profound impacts on people's health and on businesses in the food manufacture and distribution sectors. The awareness and knowledge of natural and synthetic toxins and toxicants in food has improved significantly in the last two decades via extensive worldwide collaborative research work and monitoring programmes.

The provision of reliable data from the use of advanced and versatile technologies is now a prerequisite for the investigation of the causes of food poisoning incidents, the prevention of such events and for the production of wholesome and safe food. Attention is drawn herein to the importance of quality assurance activities, as for any analytical measurements with potential as forensic evidential use, and to the need for relevant reference materials. The value of strategic risk assessments and data modelling are shown to be keys to the setting up of appropriate limits for toxin concentrations in foods and in food components. Hence this comprehensive review of such work, much of which has been undertaken with worldwide collaborations, to produce data using validated analytical methodologies is considered to be most timely.

The editors are to be congratulated for their selection of relevant and interesting topics. The various section authors have produced a readable, in-depth survey of the current position in the analysis of food toxins and toxicants and also have drawn attention to some important residual problems in certain areas concerning reference materials.

The volume is divided into five main sections: I (Chapters 1–4). Recent developments in analytical technology including sample pre-treatment and food additives; II (Chapters 5–10). Microbial and plant toxins, including plant pyrrolizidine alkaloids; III (Chapters 11–15). Marine toxins in fish and shellfish; IV (Chapters 16–19). Biogenic amines and common food toxicants, such as pesticides and heavy metals; V (Chapters 20–24). Quality assurance and recent developments in regulatory limits for toxins, toxicants and allergens, which includes discussions on laboratory accreditation and reference materials.

Due to the excellent editorial control all the chapters are easy to follow, coherent in layout and are comprehensively referenced, which most helpfully indicate the papers' contents by giving their titles in full.

This up-to-date set of accounts of analytical approaches available and the problems to be encountered in the detection and estimation for a variety of food toxins will be useful to analytical chemists working in academic, manufacturing, distribution and regulatory food control laboratories.

Preface

Food toxins and toxicants are widely discussed global issues, and given the threats they pose to human health, they represent one of the most important aspects of analytical chemistry. Over the past two decades, we have experienced various crises due to foodborne toxins causing profound impacts on human health and the food industry. Importantly, in countries where well-developed food management systems with reliable methods of measurement are not established, such outbreaks can lead to potentially life-threatening exposures and resource waste. Our knowledge and awareness of natural toxins and toxicants in foods have improved substantially through extensive research and worldwide networking programs in the field. Thanks to the continuous commitment and cooperation of various organizations, validated analytical methodologies can now detect sub-clinical levels of many food toxins and toxicants using advanced and versatile technologies. A comprehensive monitoring of food toxins and toxicants is a critical prerequisite to substantiate the causes of food poisonings and help prevent similar food catastrophes from taking place. The implementations of quality assurance to food toxin analysis, including the production of reference materials, strategic risk assessment and data modelling for toxin thresholds, are required to validate and strengthen the measurement applications. This book provides an up-to-date and comprehensive overview of the analytical approaches used to detect a range of food toxins. Contributions from more than 70 eminent food toxin scientists across the globe illustrate their expertise and experience to readers. We hope that it can provide useful guidance and instruction to analytical chemists and food scientists, both in industry and academia. In each chapter, the authors aim to provide a concise discussion on the latest methodology currently applied to measure a wide variety of food toxins and toxicants, including a detailed and illustrated overview of different separation and detection approaches used. Finally, we would like to express our sincere thanks to all of our renowned authors who contributed their invaluable time and their expertise to this book.
