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.

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.

Recent advances regarding the human foodborne pathogen Listeria monocytogenes are discussed with specific emphasis on epidemiology, ecology and virulence. Recent routine surveillance and outbreak investigation studies indicate a shift in L. monocytogenes serotypes linked to listeriosis in some countries. There is growing evidence to show that L. monocytogenes isolates can be divided beyond the serotype level into at least two epidemiologically and genetically distinct subpopulations differentiated by biologically meaningful markers, including strains responsible for the majority of listeriosis cases and strains carrying virulence attenuating mutations in the key virulence gene inlA, which codes for internalin A.

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.

This chapter discusses the research on the use of organic acids as decontamination agents for foods of animal and plant origin. First, the application of organic acids to meat decontamination (i.e., carcasses and trimmings) is presented followed by an overview of research into the use of organic acids for decontaminating vegetables, fruits and fruit juices. Both single and multiple interventions are discussed. Then, the potential concerns of microbial adaptation to acid treatments are examined and the current legislation status at international level is presented. Key points and practical implications for the industry are discussed in the final section of the chapter.

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.

Viruses are common causes of foodborne outbreaks. Viral diseases have low fatality rates but transmission to humans via food is important due to the high probability of consuming fecally contaminated food or water because of poor food handling. Because of the low infectious doses of some foodborne viruses, there is a need for standardization and the development of new sensitive methods for detecting viruses. The focus is on molecular and non-molecular approaches, and emerging methods for the detection of foodborne viruses. The detection of noroviruses, hepatitis A and E viruses, rotaviruses and adenoviruses will be discussed. The chapter will conclude with insights into future research directions.

Omic technologies, including genomics, proteomics and metabolomics, are used to study pathogen behavior at the molecular level and develop improved pathogen detection and typing systems. Omic technologies analyze complete or nearly complete expressions of cell functions. DNA sequencing has resulted in complete genomes of foodborne pathogens. Omic-based technologies explore biological processes in a quantitative and integrative manner. They facilitate identification of genes and proteins that contribute to survival and persistence in food and other environments, that play a role in pathogenesis and that are targets for detection methods and control strategies. Challenges that remain are performing genomic and proteomic studies in food and other complex matrices and interpreting and analyzing the data produced from these investigations to enhance food safety.
