Which of the following is included in the Egg Safety Rule's preventative measures in poultry houses?

• A. Migratory bird management
• B. Biosecurity
• C. Genetic modification
• D. Antibiotic withdrawal guidelines

Answer: (B)

Biosecurity is the practice focused on preventing the introduction and spread of pathogens inside poultry houses. The Egg Safety Rule targets reducing Salmonella in eggs by requiring preventive controls within production facilities, and robust biosecurity is the core of those measures. It includes actions like restricting access to housing, changing clothing and boots when entering, cleaning and disinfection of equipment and surfaces, proper sanitation, and effective pest control. These in-house practices directly reduce the chance that pathogens enter the flock or move between flocks, which is central to keeping eggs safe.

Migratory bird management isn’t specified as a formal in-house preventive measure in this rule, and genetic modification isn’t part of the required preventive controls. Antibiotic withdrawal guidelines pertain to ensuring drug residues are absent in products, not to the in-house preventative measures aimed at preventing contamination of eggs during production.
