Titelbeschreibung

The past few years have witnessed an upsurge in incidences relating to food safety issues, which are all attributed to different factors. Today, with the increase in knowledge and available databases on food safety issues, the world is witnessing tremendous efforts towards the development of new, economical and environmentally-friendly techniques for maintaining the quality of perishable foods and agro-based commodities. The intensification of food safety concerns reflects a major global awareness of foods in world trade. Several recommendations have been put forward by various world governing bodies and committees to solve food safety issues, which are all mainly targeted at benefiting consumers. In addition, economic losses and instability to a particular nation or region caused by food safety issues can be huge. Various ‘non-dependent’ risk factors can be involved with regard to food safety in a wide range of food commodities such as fresh fruits, vegetables, seafood, poultry, meat and meat products. Additionally, food safety issues involves a wide array of issues including processed foods, packaging, post-harvest preservation, microbial growth and spoilage, food poisoning, handling at the manufacturing units, food additives, presence of banned chemicals and drugs, and more. Rapid change in climatic conditions is also playing a pivotal role with regard to food safety issues, and increasing the anxiety about our ability to feed the world safely. Practical Food Safety: Contemporary Issues and Future Directions takes a multi-faceted approach to the subject of food safety, covering various aspects ranging from microbiological to chemical issues, and from basic knowledge to future perspectives. This is a book exclusively designed to simultaneously encourage consideration of the present knowledge and future possibilities of food safety. This book also covers the classic topics required for all books on food safety, and encompasses the most recent updates in the field. Leading researchers have addressed new issues and have put forth novel research findings that will affect the world in the future, and suggesting how these should be faced. This book will be useful for researchers engaged in the field of food science and food safety, food industry personnel engaged in safety aspects, and governmental and non-governmental agencies involved in establishing guidelines towards establishing safety measures for food and agricultural commodities.
