Biosecurity zones at the hatchery

Biosecurity zones at the hatchery

A hatchery is divided into biosecurity zones. These separate zones apply to human contacts, but also to materials that have to stay in a certain zone, and separate ventilation and drainage systems. The ideal design includes five, defined biosecurity zones. 1. Egg receiving and storage zone 2. Setter zone 3. Candling and transfer zone 4. Hatching zone 5. Chick processing and dispatch It is sensible to separate the candling and transfer zones, as this is a relatively ‘dirty’ zone, certainly The biosecurity zones are visible in all installations, for example segregated if the batch contains bangers. However, you will Pathogens can enter a hatchery via many different routes. These vectors include: eggs, personnel, materials, visitors, rodents and outside air. have to keep returning to the setter room to collect new trolleys... The number of zones can also be reduced to three main zones, particularly in smaller hatcheries. 1. Egg receiving and storage 2. Setter zone 3. Chick zone (hatching, sexing, treatments and grading) Candling and transfer zoneEgg receiving and storage zone Setter zone Hatching zone Chick zone drainage and air circulation. At a hatchery, different air pressures are set for each zone. Large filter units that treat the incoming air can often be seen on one side of a hatchery, and exhaust air outlets on the other. copyright protected The biosecurity zones are separated with regard to movement of personnel, ventilation and drainage systems.
