Bio : means life Security : means protection Biosecurity is a set of preventive measures designed to reduce risk of introduction and spread of pathogens into and between farms. FAO definition of BIOSECURITY “A strategic and integrated approach that encompasses the policy and regulatory frameworks for analysing and managing relevant risks to human, animal and plant life and health and associated risks to the environment.”  Biosecurity in a broader sense encompasses ISOLATION, traffic control sanitation, vaccination, serological monitoring of diseases and air quality which will aid in prevent the entry and control of the pathogens in and around the farm.  Biosecurity is the integral part of the farm operations.  It is the defensive health plan and hygienic procedure essential in keeping the farm disease free.  It is the cheapest and at the same time most effective means of disease control available, without which no disease prevention program will work well.  As the poultry operations become more and more effective, same time they become threat to themselves and their neighbours and the concentration of more bird in limited space.  Biosecurity, vaccination / medication and good management of farm are three sides of disease triangle.  Biosecurity is the key element of triangle of disease control. Three levels of Biosecurity 1. Conceptual : The primary level of biosecurity revolves around the location of farm and the isolation facilities, limiting the access to the personnel not concerned with the farm activities 2. Structural : The secondary level of biosecurity deals with the physical factors such as farm layout, perimeter fencing, drainage facilities, housing design, feed delivery or storage. 3. Operational : The tertiary level deals with the routine procedures to prevent the introduction (bioexclusion) into a farm and spread of infection between farms (biocontainment ). These activities should be constantly reviewed and quickly adjusted as needed in response to emergencies. CONCEPTUAL BIOSECURITY  It is best to build the farm in an isolated area, at least 3 Km away from the nearest poultry in case of Breeder farms and Hatcheries, 1.6 Km in the case of commercial layer and broiler farms.  Breeder farms should be away from the roadways used for the transport of commercial birds and backyard poultry.  Maintain minimum distance between different farm buildings with in a farm i.e atleast 1m. STRUCTURAL BIOSECURITY • Fencing of farm perimeter to prevent unwanted visitors. • Testing water source for minerals, bacterial and chemical contamination, pathogen load. • Concrete stages with suitable water and power supply for sanitation of vehicles • Suitable location for storage of bagged feed. • All-weather roads within the farm to ease cleaning and to prevent spreading of microbes by vehicles and foot wear. • Facilities for safe scientific disposal of dead birds. • Safe housing, with suitable wild birds and rodent proofing. • Feed, litter and

2. Biosecurity
“Bio” refers to “life”
“Security” implies “protection”
Biosecurity is a set of preventive measures designed
to reduce the risk of introduction and spread of
diseases into and between the farms.
“A strategic and integrated approach that
encompasses the Policy and regulatory frame work for
analysing and managing relevant risks to human,

BIOSECURITY
Basic principles of biosecurity
1.Isolation
2.Sanitation
3.Traffic control

4.  Location of the farm and limiting the access to outside personnel
 Maintenance of distance from the breeder farm, hatchery units and other farms
 Distance b/w 2 broiler houses – 9m (30 ft)
2 farms -- 1.6 Km
breeder farms – 3 Km
Hatchery & other farms - 460 m
3m boundary of land around building – vegetation & wildlife free
 Fencing of the perimeter, house design, rodent and insect proof housing, proper drainage facilities
 Concrete flooring , water and vermin proof houses for the feed stores.
 Routine practices of cleaning and disinfection, footbath at the entry of farm and also sanitation of drinking
water
 Disinfection between batches and also maintaining down time
 Regular cleaning of equipment after every use
 Proper disposal of dead birds

9. Foot bath for vehicles at the entry Foot bath at the entrance of farms Showering of personal at the entry
Disinfection of equipment. Disinfection of vehicles
How to Stop the ENTRY of infectious agent Into the farm ????

10. • Separate vehicles for handling of feedstuffs and vehicles.
• Limiting vehicle and foot traffic within the farm boundaries.
• Maintain separate vehicles for inside and outside farm operations.
• Proper disposal of dead birds.
• Separation of sick birds from healthy ones.
• Sanitation of water lines.
• Periodical checks of feed and water quality.
• Flow of operations must be always from younger birds to older (CHICKS,
GROWERS, LAYERS )
• Sick birds must be attended after healthy birds.
Stop the buildup and spread of infectious agent WITH IN THE FARM

11. • Self quarantine.
• Adopting enhanced biosecurity.
• Suspending all unnecessary traffic.
• Proper disposal of dead birds after conducting post mortem
• Reporting suspicion of infectious disease
• Alerting neighboring poultry farms
Stop the ESCAPE of Infectious agent off the farm
