In nature, microorganisms are generally found attached to surfaces as biofilms such as dust, insects, plants, animals and rocks, rather than suspended in solution. Once a biofilm is developed, other microorganisms are free to attach and benefit from this microbial community. The food industry, which has a rich supply of nutrients, solid surfaces, and raw materials constantly entering and moving through the facility, is an ideal environment for biofilm development, which can potentially protect food pathogens from sanitizers and result in the spread of foodborne illness. Biofilms in the Food Environment is designed to provide researchers in academia, federal research labs, and industry with an understanding of the impact, control, and hurdles of biofilms in the food environment. Key to biofilm control is an understanding of its development. The goal of this 2nd edition is to expand and complement the topics presented in the original book. Readers will find: The first comprehensive review of biofilm development by Campylobacter jejuni An up-date on the resistance of Listeria monocytogenes to sanitizing agents, which continues to be a major concern to the food industry An account of biofilms associated with various food groups such as dairy, meat, vegetables and fruit is of global concern A description of two novel methods to control biofilms in the food environment: bio-nanoparticle technology and bacteriophage Biofilms are not always a problem: sometimes they even desirable. In the human gut they are essential to our survival and provide access to some key nutrients from the food we consume. The authors provide up-date information on the use of biofilms for the production of value-added products via microbial fermentations. Biofilms cannot be ignored when addressing a foodborne outbreak. All the authors for each chapter are experts in their field of research. The Editors? hope is that this second edition will provide the bases and understanding for much needed future research in the critical area of ?Biofilm in Food Environment?.

Materials and equipment in food processing industries are colonized by surface-associated microbial communities called biofilms. In these biostructures microorganisms are embedded in a complex organic matrix composed essentially of polysaccharides, nucleic acids and proteins. This organic shield contributes to the mechanical biofilm cohesion and triggers tolerance to environmental stresses such as dehydratation or nutrient deprivation. Notably, cells within a biofilm are more tolerant to sanitation processes and the action of antimicrobial agents than their free living (or planktonic) counterparts. Such properties make conventional cleaning and disinfection protocols normally not effective in eradicating these biocontaminants. Biofilms are thus a continuous source of persistent microorganisms, including spoilage and pathogenic microorganisms, leading to repeated contamination of processed food with important economic and safety impact. Alternatively, in some particular settings, biofilm formation by resident or technological microorganisms can be desirable, due to possible enhancement of food fermentations or as a means of bioprotection against the settlement of pathogenic microorganisms. In the last decades substantial research efforts have been devoted to unravelling mechanisms of biofilm formation, deciphering biofilm architecture and understanding microbial interactions within those ecosystems. However, biofilms present a high level of complexity and many aspects remain yet to be fully understood. A lot of attention has been also paid to the development of novel strategies for preventing or controlling biofilm formation in industrial settings. Further research needs to be focused on the identification of new biocides effective against biofilm-associated microorganisms, the development of control strategies based on the inhibition of cell-to-cell communication, and the potential use of bacteriocins, bacteriocin-producing bacteria, phage, and natural antimicrobials as anti-biofilm agents, among others. This Research Topic aims to provide an avenue for dissemination of recent advances within the “biofilms” field, from novel knowledge on mechanisms of biofilm formation and biofilm architecture to novel strategies for biofilm control in food industrial settings.

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

Raising the average human lifespan by a decade or more will change our world. The future is not about whether this will happen; it is about what we should do when it happens. Even the most pessimistic assertions about the future of our environment are underestimating the extent of the problem. There is simply no model in which more years of life does not equate to more people and in which that does not lead to more crowding, environmental degradation, more consumption, and more waste. Hence, as we prolong life, these environmental crises will be further exacerbated. With current diets and production practices, feeding 7,6 billion people is degrading terrestrial and aquatic ecosystems, depleting water resources, and driving climate changes. The challenges of today are not just population, and it’s not just consumption, it is waste also. Thanks to things such as cars, planes, big homes, deforestation and so forth, the annual carbon dioxide emissions of an average are three times as high as it should be. It is likely that this signals that the current level of dividends is unsustainable, hence, we use and return little of value to our natural world. In our book, we address the questions related to environmental health challenges that include contamination of air, water, and soil, and car transportation. In order to better understand natural, industrial, and social-environmental hazards, we have to think of them in a broader context (i.e., physical, chemical, biological, and cultural). We hope that the presented publication gives the reader a broader perspective on the issues related to environmental health challenges in contemporary society in the coming years.
