Download or read book Consumer Phase Risk Assessment for Listeria Monocytogenes in Deli Meats written by Hong Yang and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foodborne disease risk associated with the pathogen Listeria monocytogenes has been the subject of recent efforts in quantitative microbial risk assessment. Building upon one of these efforts undertaken jointly by the U.S. Food and Drug Administration and the U.S. Department of Agriculture (USDA), the purpose of this work was to expand on the consumer phase of the risk assessment to focus on handling practices in the home. One-dimensional Monte Carlo simulation was used to model variability in growth and cross-contamination of L. monocytogenes during food storage and preparation of deli meats. Simulations approximated that 0.3% of the servings were contaminated with >10(6) CFU/g of L. monocytogenes at the time of consumption. The estimated mean risk associated with the consumption of deli meats for the intermediate-age population was approximately 7 deaths per 10(11) servings. Food handling in homes increased the estimated mean mortality by 10(6)-fold. Of all the home food-handling practices modeled, inadequate storage, particularly refrigeration temperatures, provided the greatest contribution to increased risk. The impact of cross-contamination in the home was considerably less. Adherence to USDA Food Safety and Inspection Service recommendations for consumer handling of ready-to-eat foods substantially reduces the risk of listeriosis.

This book was released on 2008 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of meats and meat products, including fermented sausages and deli meats, can be contaminated with Listeria spp. Contamination of luncheon meats b y Listeria monocytogenes has resulted in outbreaks of listeriosis and major prod uct recalls. Proper storage and handling of refrigerated ready-to-eat foods can help reduce the risk of listeriosis. The purpose of this work was to measure the awareness and knowledge of consumers and workers in deli meat sectors regarding Listeria spp., to investigate the microbiological quality and safety of the del i meat products in Lebanon with respect to Listeria spp., and to study the survi val of the pathogen. On the sample of 100 consumers and 20 employees tested, app roximately 70% of the Lebanese consumers and 45% of the workers in deli meat sec tors were not aware about the possible contamination of deli meats with Listeria spp. Further, a total of nine swabs from equipment surfaces and 40 deli meat sa mples were collected from different retail outlets in Beirut regions and were te sted for the presence of Listeria spp. by cultural methods. Listeria monocytogen es was isolated from five swabs (55.5%) and three samples (7.5%) and Listeria in nocua from eight swabs (88.8%) and 13 samples (32.5%). The counts ranged from le ss than 100 to less than 10 (to the power 5) CFU/g for both Listeria monocytogen es and Listeria innocua, showing a significant level of contamination. The resul ts pinpointed the significant effect of equipment contamination with Listeria mo nocytogenes and Listeria innocua on deli meats safety. There was no significant difference in microbiological quality between samples obtained from supermarkets as compared to minimarkets. Also, there was no significant difference in microb iological quality of deli meats from beef, pork or chicken sources. Further, the isolated Listeria innocua and Listeria monocytogenes were tested for resistance to various sanitizers and detergents commonly used in the outlets. Suspected Li steria monocytogenes and Listeria innocua were highly or intermediate resistant to the detergents and sanitizers. Results of the present work indicate that enum erated Listeria monocytogenes and Listeria innocua in deli meats were higher tha n acceptable standards with strains being resistant to sanitizers used, making t he product a potential ...

In addition, the efficacy of each type of antimicrobial, used alone or in combination with other food preservation methods, is considered. Factors that limit the use of antimicrobials as food preservatives, such as moisture, temperature, and the ingredients comprising foods, are also discussed. Finally, consumer perspectives related to the acceptance of various preservation approaches for processed foods are described.

Download or read book Foodborne Pathogens written by Joshua B. Gurtler and published by Springer. This book was released on 2017-06-14 with total page 653 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Risk Assessment Methods for Biological and Chemical Hazards in Food written by Fernando Pérez-Rodríguez and published by CRC Press. This book was released on 2020-10-28 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has been extensively developed in several scientific fields, such as environmental science, economics, and civil engineering, among others. In the aftermath of the SPS and GATT agreements on the use of risk analysis framework in food trade, signed in the 1990s, international organisations and governments adopted risk assessment as a science-based process to ensure food safety along the food chain. The food industry can also benefit from the use of this approach for food process optimisation and quality assurance. Risk Assessment Methods for Biological and Chemical Hazards in Food introduces the reader to quantitative risk assessment methods encompassing general concepts to specific applications to biological and chemical hazards in foods. In the first section, the book presents food risk assessment as methodology and addresses, more specifically, new trends and approaches such as the development of risk rating methods, risk metrics, risk-benefit assessment studies and quality assessment methods. Section II is dedicated to biological hazards. This section identifies the most relevant biological hazards along the food chain and provides an overview on the types of predictive microbiology models used to describe the microbial response along the food chain. Chapter 12 specifically deals with cross contamination and the quantitative methods that can be applied to describe this relevant microbial process. The development and application of dose-response models (i.e. mathematical function describing the relationship between pathogen dose and health response) are also covered in this section. In Section III, the book translates risk assessment concepts into the area of chemical hazards, defining the process steps to determine chemical risk and describing the uncertainty and variability sources associated with chemicals. Key Features: Presents new trends and approaches in the field of risk assessment in foods Risk assessment concepts are illustrated by practical examples in the food sector Discusses how quantitative information and models are integrated in a quantitative risk asssment framework Provides examples of applications of quantitative chemical risk assessment in risk management The book, written by renowned experts in their field, is a comprehensive collection of quantitative methods and approaches applied to risk assessment in foods. It can be used as an extensive guide for food safety practitioners and researchers to perform quantitative risk assessment in foods
