Food Safety in Poultry Meat Production


Book Description

This comprehensive study of poultry meat safety offers readers the most up-to-date information on food safety concerns in poultry meat production. Chapters address recent topics of interest such as organic poultry production, antimicrobial resistant pathogens in poultry, antibiotic usage in poultry production, and pre- and post- harvest approaches to improving poultry meat safety. The last couple of decades have observed a significant increase in poultry meat production in the US. However, poultry meat is a potential source of foodborne pathogens such as Salmonella, Campylobacter spp. and pathogenic Escherichia coli (APEC linked to human infections), leading to economic losses to the poultry industry and impacting public health. Advances in knowledge in microbiology, molecular biology, immunology and “omics” fields have intensified efforts to improve the microbiological safety of poultry by targeting virulence mechanisms of the pathogens, developing vaccines and improving gut health in chickens. Moreover, due to the emergence of multidrug resistance in poultry-borne pathogens, and growth of organic poultry production, there exists significant interest for developing natural strategies for controlling pathogens in chickens. This edited volume provides insight into these strategies and covers other material of interest to food microbiologists, public health personnel, and poultry scientists. Readers of various backgrounds will appreciate its incorporation of recent developments not covered in other publications on the subject.




Prebiotics and Probiotics


Book Description

Probiotic bacteria are found in the intestinal microbiota of the host and favor multiple metabolic reactions. Prebiotics provide food for probiotic bacteria and have an effect on their own performance in favor of host health. Numerous metabolic and immunological mechanisms are involved in its effects. Probiotics have been studied for several decades and their use for human consumption is still unclear. However, new types of molecules with prebiotic functions and components of probiotic bacteria with therapeutic potential are still being studied. The versatility of these molecules makes their incorporation into human food and animal diets feasible. This book is a compendium of recent scientific information on the use of probiotics and prebiotics for the benefit of human and animal health.




Probiotics in Poultry Production


Book Description

Probiotics are live microbial feed supplements that beneficially affect the host by improving its intestinal microbial balance. The microorganisms come from a whole range of defined strains of probiotics belonging to the groups of lactic acid bacteria, Bacillus spores, and yeasts. Research in nutritional physiology demonstrates the critical importance of a balanced gut microflorain in animal and human physiology. The probiotic concept is concerned with optimizing nutritional intake and digestion by promoting the gut flora perspective. Probiotics act by reducing the feed conversion, resulting in an increase of the daily live weight gain. The improvement of the growth of an animal is achieved through a natural, physiological way: improving digestion by balancing the gut flora, helping the animal to fulfill its genetic potential. This book discusses probiotics' mode of action and probiotics' practical application in poultry production, while explaining the use of probiotics in preventing and fighting poultry diseases, such as Salmonellosis, Necrotic Enteritis, Coccidiosis, bacterial lameness, etc. It will be essential reading for a wide group of readers, including university staff, feed mill companies, poultry producers, veterinarians, and researchers in the field.
