Listeriosis, a foodborne disease caused by Listeria monocytogenes is a major concern for public health authorities. In addition, addressing issues relating to L. monocytogenes is a major economic burden on industry. Awareness of its ubiquitous nature and understanding its physiology and survival are important aspects of its control in the food processing environment and the reduction of the public health concern.
Book Synopsis Biofilms in the Food and Beverage Industries by : P. Fratamico
Download or read book Biofilms in the Food and Beverage Industries written by P. Fratamico and published by CRC Press. This book was released on 2009-10-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilms in the Food and Beverage Industries reviews the formation of biofilms and the best practices for their control. When bacteria attach to and colonize the surfaces of food processing equipment and food 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. Part one 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 beneficial reference for microbiologists and those in industry responsible for food safety.
Book Synopsis Biofilms in the Food Environment by : Anthony L. Pometto III
Download or read book Biofilms in the Food Environment written by Anthony L. Pometto III and published by John Wiley & Sons. This book was released on 2015-11-02 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food safety is of paramount importance for production of wholesome and nutritious food. Throughout my dissertation, I present results of four studies exploring the relationship between Listeria monocytogenes, a deadly foodborne pathogen, and environmental microbiota found in food processing facilities. L. monocytogenes can inhabit a wide range of habitats (e.g., soil, water, animals, insects) and its ability to adapt to different environmental conditions (e.g., low temperatures, high salt concentrations, low pH) allows for its survival in food processing environments, which can result in the potential for recurring contamination of food. To control the presence of L. monocytogenes, food processors rely on cleaning and sanitizing operations coupled with Environmental Monitoring Programs. While L. monocytogenes is typically susceptible to the cleaning and sanitizing protocols applied in food processing facilities, it may survive the action of sanitizers by forming, or residing inside biofilms. However, in food processing environments, L. monocytogenes resides with other environmental microorganisms that are introduced to the facilities with raw products or personnel. The presence of other microorganisms can facilitate formation of robust multi-species biofilms that may enhance the survival and persistence of L. monocytogenes. Currently, limited information is available regarding the potential associations between environmental microbiota and the presence of foodborne pathogens in food processing facilities. My dissertation research aimed to address some of the critical gaps in the understanding of the role of environmental microbiota in the survival and persistence of L. monocytogenes in food processing environments. iv To begin unraveling the role of environmental microbiota in the persistence of L. monocytogenes in food processing environments, I first sought to characterize the microbiota of three tree fruit packing facilities and statistically assess whether certain taxa co-occur with L. monocytogenes (Chapter 2). I observed a recurring presence of L. monocytogenes and a distinct microbiota composition in the monitored facilities throughout two seasons. Importantly, I found that bacterial taxa from taxonomic families Pseudomonadaceae, Xanthomonadaceae, and Microbacteriaceae were present in a significantly higher relative abundance in L. monocytogenes-positive samples, especially in the facility with a persistent L. monocytogenes contamination. While some members of these bacterial families have been studied as food spoilage organisms (e.g., Pseudomonas spp.), emerging human pathogens (e.g., Stenotrophomonas spp.), or plant pathogens (e.g., Xanthomonas spp.), there is limited information available on potential interactions between these species and L. monocytogenes. Furthermore, their role in the survival and persistence of L. monocytogenes in food processing facilities is severely understudied. In Chapter 3, I seek to understand how the detected bacterial taxa interact with L. monocytogenes. Given that the survival of L. monocytogenes under sanitizer pressure may be facilitated by biofilms formed in food processing environment, I aimed to assess the effect of biofilms formed by environmental microbiota on the survival during exposure to a commonly used sanitizer, benzalkonium chloride. I isolated environmental microbiota from families Pseudomonadaceae, Xanthomonadaceae, Microbacteriaceae, and Flavobacteriaceae from tree fruit packing environments, and tested their ability to form biofilms in single- and multi-family assemblages with L. monocytogenes. I found that microbial assemblages of v increasing complexity (i.e., increasing number of families) generally formed more biofilm and contained a greater concentration of L. monocytogenes, compared to monoculture biofilms. I further tested the effects of multi-species biofilm formation on the sanitizer tolerance of L. monocytogenes, by exposing multi-species biofilms to sanitizers and quantifying the die-off kinetics of L. monocytogenes throughout a 2-hour period. In Chapter 4, I aimed to assist fruit packers by providing practical tools to enhance the control of L. monocytogenes through traditional chemical-based cleaning and sanitizing. I tested four cleaning and sanitizing cleaning and sanitizing protocols in the fruit packing environments to determine their effectiveness in controlling L. monocytogenes and examined their effect on environmental microbiota. I found that the cleaning and sanitizing protocol that included a disinfectant with a biofilm-degrading ability was most effective in reducing the frequency of detected L. monocytogenes in the sampled areas. While the total microbial load generally decreased after the application of cleaning and sanitizing protocols, the microbiota composition did not appear to be significantly affected by the treatments. In the last research chapter (Chapter 5), I tested the ability of two lactic acid bacteria strains to inhibit L. monocytogenes in a monoculture as well as in the context of environmental microbiota from food processing facilities. Microbial strains with antilisterial activity have been previously assessed as alternative strategy to control L. monocytogenes in food processing environments, however, their performance in the context of environmental microbiota from ice cream processing facilities has not been tested before. Here, I collected environmental microbiota from three small-scale ice cream processing facilities and tested whether two lactic acid vi bacteria could attach and effectively inhibit L. monocytogenes when co-cultured with the collected environmental microbiota. I observed that the microbiota composition of ice cream processing facilities may affect the antilisterial ability of two lactic acid bacteria strains and their attachment to surfaces. In particular, the presence of Pseudomonas significantly reduced the antilisterial ability of the tested strains. The knowledge generated through my studies on the role of food processing facilities' microbiota will aid in designing tailored cleaning, sanitizing, and/or biological control protocols for control of L. monocytogenes. For example, cleaning and sanitizing could be redesigned to control taxa that facilitate Listeria's persistence, or new cleaning chemistries can be developed to improve biofilm control in food processing facilities.

This book was released on 2018-01-22 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2017 in the subject Medicine - Epidemiology, grade: 1, Egerton University, language: English, abstract: Listeria monocytogenes remains to be one of the most leading causes of food-borne illnesses. It has become a serious problem in food manufacturing plants owing to its food poisoning capability which threatens the health of food products’ consumers, especially in the United States where food processing occur at a high magnitude compared to other parts of the world. Stephan and Jemmi (2006) report “listeriosis ranks among the most frequent causes of death due to food-borne illness. L. monocytogenes infections are responsible for the highest hospitalization rates (91%) amongst known food-borne pathogens and have been linked to sporadic episodes and large outbreaks of human illness worldwide”. This is attributable to its high case fatality, and this is probably the principal reason as to why L. monocytogenes is regarded as one of the most significant food-associated pathogen. This Gram-positive bacterium causes human listeriosis and contamination with L. monocytogenes has been one of the principal microbiological causes of processed food recalls, primary in regard to seafood, poultry, meat and dairy products such as milk and cheese. Research report indicates that the increased pathogenicity of L. monocytogenes is enhanced by its adaptability to food-processing environments. For instance, this bacterium can thrive and multiply under refrigeration conditions. It has also been found to thrive in drains in food processing plants. Moreover, L. monocytogenes ability to form biofilms enhances its colonization, distribution and adaptation to a wide range of environmental conditions including adverse temperatures and PH ranges. Therefore, this paper will discuss the detection and identification of L. monocytogenes, and present comprehensive implementation of Listeria intervention strategies to control contamination of food products with the food-borne pathogen.

Book excerpt: Foodborne illnesses continue to be a major public health concern. All members of a particular bacterial genera (e.g., Salmonella, Campylobacter) or species (e.g., Listeria monocytogenes, Cronobacter sakazakii) are often treated by public health and regulatory agencies as being equally pathogenic; however, this is not necessarily true and is an overly conservative approach to ensuring the safety of foods. Even within species, virulence factors vary to the point that some isolates may be highly virulent, whereas others may rarely, if ever, cause disease in humans. Hence, many food safety scientists have concluded that a more appropriate characterization of bacterial isolates for public health purposes could be by virotyping, i.e., typing food-associated bacteria on the basis of their virulence factors. The book is divided into two sections. Section I, “Foodborne Pathogens and Virulence Factors,” hones in on specific virulence factors of foodborne pathogens and the role they play in regulatory requirements, recalls, and foodborne illness. The oft-held paradigm that all pathogenic strains are equally virulent is untrue. Thus, we will examine variability in virulence between strains such as Listeria, Salmonella, Campylobacter, Cronobacter, etc. This section also examines known factors capable of inducing greater virulence in foodborne pathogens. Section II, “Foodborne Pathogens, Host Susceptibility, and Infectious Dose” , covers the ability of a pathogen to invade a human host based on numerous extraneous factors relative to the host and the environment. Some of these factors include host age, immune status, genetic makeup, infectious dose, food composition and probiotics. Readers of this book will come away with a better understanding of foodborne bacterial pathogen virulence factors and pathogenicity, and host factors that predict the severity of disease in humans.
Book Synopsis Improving Food Safety Through a One Health Approach by : Institute of Medicine
Download or read book Improving Food Safety Through a One Health Approach written by Institute of Medicine and published by National Academies Press. This book was released on 2012-09-10 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.
