Routine biosecurity maintenance shall include daily inspection of footbaths, verification of disinfectant concentration, cleaning of spillages, mortality disposal, shed perimeter hygiene, and strict compliance with personnel entry protocols.

To prevent viral entry, you must establish a clear Three-Zone System (Dirty, Buffer, and Clean) where anyone entering the sheds is required to “shower-in” and utilize farm-specific clothing and footwear. Physical barriers, such as bird-proof mesh are vital to block wild bird and rodent vectors, while structural measures like wheel dips and footbaths—regularly recharged with disinfectants like Peroxymonosulfate—mitigate mechanical transmission. Operational hygiene must include continuous water sanitation, secure feed storage and a mandatory 48-to-72 hour downtime for any essential visitors. Finally, immediate and secure disposal of carcasses through incineration or deep burial ensures that the farm environment does not become a reservoir for persistent viral pathogens.

Strict traffic control, rigorous cleaning and disinfection cycle, maintaining sufficient downtime to break the pathogen cycle between flocks.

The most effective biosecurity step are restricting farm access ,disinfecting equipment and foot wear,controling visitor and vehicles,isolating new birdsand mainting stick hygine practice.
