Few titles could be timelier than the second edition of Crisis Management in the Food and Drinks Industry - A Practical Approach. The world is worrying about a human pandemic arising from the avian flu epidemic that is spreading from the Far East, the implications of which could be as great for the food industry as were the outbreaks of foot and mouth disease and BSE.
This practical and greatly expanded edition by media and public relations veteran Colin Doeg focuses on the communications aspects of dealing with a crisis. It is global in its coverage of the subject, reviewing practices and requirements in countries ranging from the USA and the UK to Australia and New Zealand.
Doeg offers advice ranging from preparing for the unthinkable to the dramatic expansion of the Internet, avoiding being caught off-guard by a situation, the ramifications of product tampering and managing an actual crisis.
Advice is also offered on dealing with extremist organizations and terrorist threats as well as bioterrorism - "a clear and present danger" - and a number of problems facing the food industry, including the practice of selling meat unfit for human consumption and the threat posed by the increasing toxicity of fish due to the rising pollution of the world's oceans.
In a special late chapter - written only three months before publication - the author looks ahead to events which he believes will shape the world of crisis management in the future, including the empowering influence of the Internet during the 2004 Asian Tsunami, the discovery of the illegal dye Sudan 1 (Red) in millions of food products and the fears of a pandemic arising from the spreading outbreak of avian flu.
Examples of typical documents like a crisis plan for a business, a crisis checklist, a press release announcing a product recall, an announcement to employees and a checklist for anyone dealing with a threatening phone call are provided. Also included is a list of sources of information and assistance in the event of a product crisis.
Crisis Management in the Food and Drinks Industry is the only title dealing specifically with this crucial subject in relation to the food industry. As such, it is relevant not only to those in the food industry, but also to marketing and senior management in general in the fields of agriculture, public health and law enforcement.

Описание: Recent developments in nanoparticle and microparticle delivery systems are revolutionizing delivery systems in the food industry. These developments have the potential to solve many of the technical challenges involved in creating encapsulation, protection, and delivery of active ingredients, such as colors, flavors, preservatives, vitamins, minerals, and nutraceuticals. Nanoparticle- and Microparticle-based Delivery Systems: Encapsulation, Protection and Release of Active Compounds explores various types of colloidal delivery systems available for encapsulating active ingredients, highlighting their relative advantages and limitations and their use. Written by an international authority known for his clear and rigorous technical writing style, this book discusses the numerous kinds of active ingredients available and the issues associated with their encapsulation, protection, and delivery. The author takes a traditional colloid science approach and emphasizes the practical aspects of formulation of particulate- and emulsion-based delivery systems with food applications. He then covers the physicochemical and mechanical methods available for manufacturing colloidal particles, highlighting the importance of designing particles for specific applications. The book includes chapters devoted specifically to the three major types of colloidal delivery systems available for encapsulating active ingredients in the food industry: surfactant-based, emulsion-based, and biopolymer-based. It then reviews the analytical tools available for characterizing the properties of colloidal delivery systems, presents the mathematical models for describing their properties, and highlights the factors to consider when selecting an appropriate delivery system for a particular application backed up by specific case studies. Based on insight from the author’s own experience, the book describes why delivery systems are needed, the important factors to consider when designing them, methods of characterizing them, and specific examples of the range of food-grade delivery systems available. It gives you the necessary knowledge, understanding, and appreciation of developments within the current research literature in this rapidly growing field and the confidence to perform reliable experimental investigations according to modern international standards.

Описание: This book covers not only the basics of retail food safety, but goes into great depth in key areas, including the control of important retail pathogens such as Listeria monocytogenes and foodborne viruses. Many different facets of retail food safety from farm-to-fork are discussed, including Retail Preventive Control Plans, HACCP, and food handler certification and training. Important new areas such as the Global Food Safety Initiative, which offers international recognition of established food safety schemes, are also described in great detail. Sanitation in the retail environment is very complex in nature, and this creates challenges when trying to develop and execute an effective sanitation program. These challenges, along with their solutions, are dealt with in detail. The chapter on retail food safety in Europe gives an excellent description of the hazards and controls in food retail and sets them against the European legal framework, using the United Kingdom as an example of their application. The book finishes with an examination of retail food safety risks for populations of different races, ethnicities and income levels, and talks about the need to better understand the barriers to food safety and sanitation that face both retailers and consumers who own and shop in small grocery and convenience stores. Retail Food Safety is an excelling resource for all food safety professionals working in the retail industry, food trade associations, all government agencies which have responsibility for retail food safety, and academics involved in teaching and/or consulting. --
