This collection features five peer-reviewed reviews on improving biosecurity in livestock production. The first chapter highlights the importance of implementing biosecurity measures along the pig production chain as a means of minimising disease introduction (external biosecurity) and spread (internal biosecurity) throughout the farm. The second chapter reviews the diagnosis and monitoring of common pig diseases, as well as the control measures that can be implemented on the farm, focussing on the importance of establishing effective biosecurity measures. The third chapter provides a brief overview of the emergence and re-emergence of several infectious pathogens of poultry. The chapter highlights the integral role of improving biosecurity in poultry flocks as a means of mitigating future disease risk, including proper cleaning and disinfection techniques. The fourth chapter provides an overview of good farming practices for beef cattle farms, with particular discussion of biosecurity, animal welfare and the importance of clean cattle policies. The final chapter summarises key issues of biosecurity which arise in organic animal farming and discusses their significance to human health. Two case studies are presented to demonstrate the successful implementation of biosecurity plans as a means of reducing disease risk.

This collection features five peer-reviewed reviews on managing bacterial diseases of poultry. The first chapter provides a brief overview of Campylobacter in poultry production and the routes of transmission from bird to human. It considers current and future challenges in controlling Campylobacter, as well as the control measures implemented to reduce the occurrence of infection in poultry flocks. The second chapter discusses economically-important enteric diseases and disorders of poultry. The chapter highlights the aetiology of these diseases and explores more sustainable alternatives to promote gastrointestinal health, such as plant-derived extracts, organic acids, prebiotics and probiotics. The third chapter provides an overview of best practices to manage disease outbreaks in poultry. It reviews current disease preventative measures, health monitoring procedures, as well as disease investigation techniques. The fourth chapter reviews the emergence and re-emergence of several infectious pathogens in poultry production and the consequent need to improve current biosecurity measures in poultry flocks to ensure optimal animal health and welfare. The final chapter considers the main alternatives to antibiotics in preventing zoonoses and other major pathogens in poultry. The chapter reviews the sector's use of prebiotics and related compounds, as well as the beneficial effects of their use.
