Improving the Safety and Quality of Eggs and Egg Products is a major, up-to-date resource covering foodborne disease, understanding of the factors influencing egg quality, new technologies to assure egg safety, and more.
Features of Volume 2: Egg Safety and Nutritional Quality:
- egg safety and nutritional quality with reference to egg contaminants such as Salmonella Enteritidis
- monitoring and control procedures in laying flocks and egg decontamination methods
- role of eggs in nutrition and other health applications including dietary cholesterol, egg allergy, egg enrichment and bioactive fractions of eggs
Part One covers egg contaminants, both microbial pathogens and chemical residues.
Part Two focuses on salmonella control in laying hens, covering essential topics such as monitoring and control procedures in laying flocks and egg decontamination methods.
Part Three looks at the role of eggs in nutrition and other health applications, and addresses dietary cholesterol, egg allergy, egg enrichment and bioactive fractions of eggs, among other topics.
