Introduction
Risk and uncertainty. These terms are very often mentioned in the media. But what is their real meaning? Are they important for our daily life? This book explains these terms in the context of our food chain. It provides a number of food-related examples of how scientists measure, assess, and manage potential risks and how this helps us to decide what is safe and not safe. The examples have one thing in common: They deal with problems that are man-made. The first chapter sets the stage: Risk examples are given from our daily life, illustrating what we need to know about risks and how to manage them. This knowledge forms the basis to guide you through the three remaining thematic chapters, where more specific topics and examples are discussed. The second chapter looks at biodiversity. Almost two million species have now been identified and the actual number of species in the world is estimated to be between 10–30 million. This enormous biodiversity is an essential provider of ecosystem goods and services to our society. However, despite the important role biodiversity plays in our lives, all species that together comprise biodiversity face risk. The third chapter investigates the risks chemical contaminants pose to our health through the food chain. The issue of food consumption has evolved from a relatively short chain of trading between producer and consumer to a complex chain where dif
