The dairy chain is an integral part of global food supply, with dairy food products a staple component of recommended healthy diets. The dairy food chain from production through to the consumer is complex, with various opportunities for microbial contamination of ingredients or food product, and as such interventions are key to preventing or controlling such contamination. Dairy foods often include a microbial control step in their production such as pasteurization, but in some cases may not, as with raw milk cheeses. Microbial contamination may lead to a deterioration in food quality due to spoilage organisms, or may become a health risk to consumers should the contaminant be a pathogenic microorganism. As such food safety and food production are intrinsically linked. This Research Topic eBook includes submissions on issues relating to the microbiological integrity of the dairy food chain, such as the ecology of pathogenic and spoilage organisms through the dairy farm to fork paradigm, their significance to dairy foods and health, and genomic analysis of these microorganisms.

In many countries of the world, the dairy industry is one of the most important food sectors and it has, by and large, been very successful in providing safe products. Nevertheless, the dairy sector, like other food sectors, also has its challenges, as from farm to the point of consumption, dairy products can become contaminated with a broad range of microbial and chemical hazards. The sources of contamination are multiple and the pathways are complex. Contamination of milk can occur directly by dairy animals shedding pathogens into the milk, or indirectly by contamination of the milk during the milking process, collection and transportation. Infected animals or asymptomatic carriers can shed the organisms in the feces and contaminate the milk through the environment. Other sources of environmental contamination are water, pests, soil, feces, pets and contaminated feed. Infected farmers, not respecting hand hygiene, are also a potential source of contamination of milk. During milking, collection and transportation, milk can be subjected to further contamination by the equipment and/or be subjected to time–temperature abuse, creating optimum conditions for microbial growth. Hence, ensuring safety of milk and dairy products starts on the farm with animal health, quality of feed, a hygienic environment and, in general, good animal husbandry. Nevertheless, pasteurization of milk is necessary to kill any surviving organisms and reduce the risk of illness to an acceptable level. Provided that hygienic measures are taken to prevent any post-process contamination, milk and dairy products can be produced and consumed safely. The present chapter reviews risks and control measures all along the production chain.

Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints. Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safetyâ€"including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Food-borne diseases, including those via dairy products, have been recognised as major threats to human health. The causes associated with dairy food-borne disease are the use of raw milk in the manufacture of dairy products, faulty processing conditions during the heat treatment of milk, post-processing contamination, failure in due diligence and an unhygienic water supply. Dairy food-borne diseases affecting human health are associated with certain strains of bacteria belonging to the genera of Clostridium, Bacillus, Escherichia, Staphylococcus and Listeria, which are capable of producing toxins, plus moulds that can produce mycotoxins such as aflatoxins, sterigmatocytin and ochratoxin. Microbial Toxins in Dairy Products reviews the latest scientific knowledge and developments for detecting and studying the presence of these toxins in dairy products, updating the analytical techniques required to examine bacterial and mould toxins and the potential for contamination of milk as it passes along the food chain, i.e. from 'farm-to-fork'. This comprehensive and accessible collection of techniques will help dairy processors, food scientists, technologists, researchers and students to further minimise the incidences of dairy food-borne illnesses in humans.
