When bacteria attach to and colonise the surfaces of food processing equipment and foods products themselves, there is a risk that biofilms may form. Human pathogens in biofilms can be harder to remove than free microorganisms and may therefore pose a more significant food safety risk. Biofilms in the food and beverage industries reviews the formation of biofilms in these sectors and best practices for their control. The first part of the book considers fundamental aspects such as molecular mechanisms of biofilm formation by food-associated bacteria and methods for biofilm imaging, quantification and monitoring. Part two then reviews biofilm formation by different microorganisms. Chapters in Part three focus on significant issues related to biofilm prevention and removal. Contributions on biofilms in particular food industry sectors, such as dairy and red meat processing and fresh produce, complete the collection. With its distinguished editors and international team of contributors, Biofilms in the food and beverage industries is a highly beneficial reference for microbiologists and those in industry responsible for food safety. Considers fundamental aspects concerning the ecology and characteristics of biofilms and considers methods for their detection Examines biofilm formation by different micro-organisms such as samonella and food spoilage Discusses specific issues related to biofilm prevention and removal, such as cleaning and sanitation of food contact surfaces and food processing equipment
Complementing the highly successful Hygiene in food processing, this book reviews recent research on improving hygiene in food processing. Part 1 considers recent research on contamination risks such as biofilms and how they can be assessed. Part 2 reviews ways of improving hygienic design of both buildings and equipment, including clean room technology. The final part of the book discusses ways of improving hygiene practice and management.
Prevention of food borne illnesses, reduction of product spoilage, and improvements to product quality are ongoing concerns in the food manufacturing industry. Providing broad but practical information, Food Plant Sanitation: Design, Maintenance, and Good Manufacturing Practices shows how to effectively remove soil and microorganisms from the proce
Outbreaks involving infected food workers in foodservice settings have resulted in many cases and deaths. Multiple-ingredient foods are most frequently associated with such outbreaks, probably because of frequent hand contact during preparation and serving. Many of the workers are asymptomatic shedders, are in contact with ill family members, handle raw foods of animal origin or use improper hygienic practices. Stools of infected persons can carry billions of pathogens and many of these become deposited on hands following defecation. Exclusion policies for food workers have limitations because of the difficulty in detecting pathogens periodically excreted in stools. Thus, barriers to contamination of food by workers include an appropriate flow of raw food to processed food in food operations, and the use of food shields, gloves, utensils and proper hand hygiene. Unfortunately, compliance with hand washing is not ideal, but can be improved through training and employee motivation. Most importantly is the culture of the organization to which the worker belongs and the knowledge, task modeling and oversight by the local person in charge.
Large volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption. This trend presents a challenge to every employee in the food processing and food prepara tion industry. Sanitation is an applied science for the attainment of hygienic conditions. Because of increased emphasis on food safety, sanitation is receiving increased attention from those in the food industry. Traditionally, inexperienced employees with few skills who have received little or no training have been delegated sanitation duties. Yet sanitation employees require intensive training. In the past, these employees, including sanitation program managers, have had only limited access to material on this subject. Technical information has been confined primarily to a limited number of training manuals provided by regulatory agen cies, industry and association manuals, and recommendations from equipment and cleaning compound firms. Most of this material lacks specific information related to the selection of appropriate cleaning methods, equipment, compounds, and sanitizers for maintaining hygienic conditions in food processing and prepara tion facilities. The purpose of this text is to provide sanitation information needed to ensure hygienic practices. Sanitation is a broad subject; thus, principles related to con tamination, cleaning compounds, sanitizers, and cleaning equipment, and specific directions for applying these principles to attain hygienic conditions in food processing and food preparation are discussed. The discussion starts with the importance of sanitation and also includes regulatory requirements and voluntary sanitation programs including additional and updated information on Hazard Analysis Critical Control Points (HACCP).
Sanitation in Food Processing is a guide to food process sanitation, which illustrates the principles with timely examples. It discusses the importance of training in food-plant sanitation programs, as well as regulatory programs relating to all aspects of food plant sanitation, including Hazard Analysis Critical Control Point (HACCP), the construction and design of food plants, and prevention of food-borne diseases. Comprised of 19 chapters, this volume begins with an overview of sanitation in food processing, good sanitation practices, and the ways to establish a successful food sanitation program. It then discusses factors to consider in the design and construction of food plants; sanitary design and operation of food processing and service equipment; microbial growth in foods; the importance of personal hygiene; and significant insects in the food industry. The reader is also introduced to ways of controlling insects, rodents, and birds in the food environment, while other chapters address sanitation in food packaging, storage, and transport. The book concludes with a summary of food laws and regulations. This book is a valuable resource for undergraduate and postgraduate students, food sanitarians, and others in the food-processing industry who want to learn more about the ways and means of ensuring the quality and safety of the food we eat.
In this era of emphasis on food safety and security, high-volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption.

The highly acclaimed textbook and reference addresses the principles related to contamination, cleaning compounds, sanitizers, cleaning equipment. It also presents specific directions for applying these concepts to attain hygienic conditions in food processing or food preparation operations. New features in this edition include: A new chapter on the concerns about biosecurity and food sanitation Updated chapters on the fundamentals of food sanitation, contamination sources and hygiene, Hazard Analysis Critical Control Points, cleaning and sanitizing equipment, and waste handling disposal Comprehensive and concise discussion about sanitation of low-, intermediate-, and high-moisture foods
Biofilms are multicellular sessile microbial communities embedded in hydrated extracellular polymeric matrices. Their formation is common in microbial life in most environments, whereas those formed on food-processing surfaces are of considerable interest in the context of food hygiene. Biofilm cells express properties that are distinct from planktonic ones, in particular, due to their notorious resistance to antimicrobial agents. Thus, a special feature of biofilms is that once they have developed, they are hard to eradicate, even when careful sanitization procedures are regularly applied. A large amount of ongoing research has investigated how and why surface-attached microbial communities develop such resistance, and several mechanisms can be acknowledged, such as heterogeneous metabolic activity, cell adaptive responses, diffusion limitations, genetic and functional diversification, and microbial interactions. The articles contained in this Special Issue deal with biofilms of some important food-related bacteria (including common pathogens such as Salmonella enterica, Listeria monocytogenes, and Staphylococcus aureus, as well as spoilage-causing spore-forming bacilli), providing novel insights into their resistance mechanisms and implications, together with novel methods (e.g., use of protective biofilms formed by beneficial bacteria, enzymes) that could be used to overcome resistance and thus improve the safety of our food supply and protect public health.
