Biosecurity refers to measures taken to prevent the introduction and/or spread of harmful organisms, such as viruses, bacteria, and parasites, to animals and plants in order to minimize the risk of transmission of infectious disease. Biosecurity is a strategic and integrated approach to analyzing and managing relevant risks to human, animal, and plant life and health and associated risks for the environment. Biosecurity includes all measures to prevent the introduction of pathogens (bio-exclusion) and reduce the spread of pathogens (bio-containment) . Biosecurity is a team effort, and everyone involved in raising poultry must use structural and operational biosecurity to prepare for and prevent disease outbreaks throughout the United States. Biosecurity can be executed in areas as large as a nation or as small as a local farm. Good biosecurity practice should be practiced at all times, not just during a disease outbreak, and taking the right measures in the early stages of an outbreak can help prevent or reduce its spread. Biosecurity plans encompass three major components of protection: physical security, personnel reliability, and information security. Physical security focuses on preventing unauthorized access to biological facilities and ensuring only the appropriate people within the facilities can access agents. Personnel reliability focuses on ensuring that all staff at a biological facility are responsible and are suitable to work with sensitive materials. Information security, which includes cybersecurity, focuses on ensuring all electronic information is safe from theft or misuse.
