New research, outbreaks of foodborne disease and changes to legislation mean that food microbiology research is constantly evolving. Advances in microbial food safety: Volume 1 summarises the key trends in this area for the food industry.The book begins with an introductory chapter discussing food safety management systems from the past to the present day and looking to future directions. The book moves on to provide updates on specific pathogens including Salmonella, Listeria monocytogenes and Bacillus species. New developments in the area are explored with chapters on emerging parasites in food, advances in separation and concentration of microorganisms from food samples, new approaches in microbial pathogen detection, and an update on novel methods for pathogen control in livestock preharvest.With its distinguished editor and international team of expert contributors, Advances in microbial food safety: Volume 1 is a standard reference for researchers, consultants and managers in the food industry responsible for food safety, analytical laboratories testing the safety of the food we eat, and researchers in academia working on food microbial safety. Summarises new research, outbreaks of foodborne disease and changes to legislation in food microbiology research Examines past, present and future food safety management systems Provides updates on specific pathogens including Salmonella, Listeria monocytogenes and Bacillus species

Research and legislation in food microbiology continue to evolve, and outbreaks of foodborne disease place further pressure on the industry to provide microbiologically safe products. This second volume in the series Advances in Microbial Food Safety summarises major recent advances in this field, and complements volume 1 to provide an essential overview of developments in food microbiology. Part one opens the book with an interview with a food safety expert. Part two provides updates on single pathogens, and part three looks at pathogen detection, identification and surveillance. Part four covers pathogen control and food preservation. Finally, part five focuses on pathogen control management. Extends the breadth and coverage of the first volume in the series Includes updates on specific pathogens and safety for specific foods Reviews both detection and management of foodborne pathogens

This chapter discusses the intervention methods used to control two helminthic diseases of public health importance. Trichinella and Taenia are transmitted by undercooked contaminated meat. Important changes made to animal husbandry and animal feeding have led to a decrease in these diseases in parts of the world. Specific information is provided on disease transmission coupled with the success achieved by intervention programs.

This chapter outlines the interactions between a hazard analysis and critical control point (HACCP) system and multiple prerequisite programs (PRPs) to produce a food-safety management program that can be applied globally throughout the food supply chain, from farm to table. The HACCP system is supported by three major PRPs: good agricultural practices, good hygienic practices and good consumer practices. While there are many effective food-safety practices and regulations, the current global system of food-safety management is poor. This chapter describes multiple barriers to food-safety progress and proposes new measures for significant improvements in global food-safety management. Such measures are necessary if HACCP is to be applied to non-traditional areas in the supply chain.

Food handler behaviour is important for producing safe food with food handler error a factor in many outbreaks. This chapter reviews food handler knowledge, attitudes and practices and the research methods used in their study. Infected food handlers spread pathogens to foods and other workers and the factors influencing this are analysed. Food handlers play a role in cross-contamination, an increasingly reported risk. The mechanisms for this and the components of hand hygiene are discussed. Historically, non-compliance has been assessed at the level of individuals. Recent work on food safety culture is examined and individual behaviour is discussed within the context of an organisation and its leadership. Methods and strategies for effective food hygiene training are reviewed.

Biotracing is a method for investigating food chain contamination events that concentrates on identification of probable sources. Biotracing is complementary to existing food safety assessments and is related to similar investigation processes in molecular epidemiology and forensic science. This chapter describes the background to biotracing, identifies important elements and describes an emerging methodology. In addition the chapter includes a review of a detailed biotracing model for Staphylococcus aureus in processed milk. The chapter concludes by highlighting options for food chain integration and includes some possibilities for future developments.

Consumers are switching to fresh, minimally processed foods, creating challenges in terms of ensuring food safety. The shift in food production from local to global has led to a complex logistics chain. These trends and challenges have lead to the development of packaging materials with better barrier properties, and active and intelligent packaging. A recent trend is the increasing sustainability of food packaging. Modified atmosphere or vacuum packaging gives a longer shelf life by reducing the growth of spoilage microorganisms and/or oxidation processes. This chapter focuses on modified-atmosphere packaging (MAP). The effects of high and low O2, elevated CO2 concentrations and equilibrium modified-atmosphere packaging (EMAP) are considered. The influence on food infectants, toxin-producing bacteria and mycotoxins is discussed. Recent studies on MAP have had contradictory results, mostly owing to differences in experimental design and materials.

In this chapter, we endeavour to predict the trends in predictive microbiology that are going to shape its development as a multidisciplinary field. We integrate the most commonly used, population and single-cell models of bacterial kinetics into a top-down framework. We predict that modellers will need to face various complexities induced by interactions at different levels: between food and microorganism, between cells and species and between molecular elements at the intracellular level. Hence, advances in the area of complex systems (e.g. network science, systems biology and stochastic modelling) will have a significant effect on the future development of predictive microbiology.

Current methods for detecting bacterial pathogens from foods and the environment are slow. Although newer, more rapid detection techniques have been developed, they have insufficient sensitivity and produce residual matrix-associated inhibitory compounds. The detection of foodborne pathogens could be more rapid if the target cells were separated and concentrated before detection, a procedure known as pre-analytical sample processing. We review sample preparation techniques, focusing on target-specific methods. Unlike non-target-specific separation/concentration methods, these approaches use bioaffinity ligands, preventing co-precipitation of target pathogens with residual matrix components. Bioaffinity ligands such as bacteriophage, phage-derived biomolecules, nucleic acid/peptide aptamers, carbohydrate ligands, antimicrobial peptides and synthetic ligands are described. The use of bioaffinity ligands in pathogen detection is new and requires further development. Such ligands have a future in foodborne pathogen detection and may allow us to substitute culture-based methods with more rapid, yet sensitive non-cultural methods.

This chapter is a series of questions and answers between John Sofos and Bruce Tompkin, giving Bruce’s perspective as a food microbiologist on food safety. Progress depends on epidemiologic studies by public health agencies and research by universities and government laboratories. Industry responded to microbial hazards and food-pathogen combinations with good manufacturing practices (GMPs) and hazard analysis and critical control point (HACCP) systems. Examples demonstrate improved consumer protection. Success depends on control measures, regulatory approval and consumer acceptance. Existing weaknesses and the underlying reasons are described. The challenge for the food safety community will be to find acceptable solutions and achieve the higher level of protection that consumers expect.
