Bio-security refers to an overall strategy or sequence of measures employed to exclude infectious diseases from a production site. Maintaining an effective bio-security program, employing good hygiene practices and following a comprehensive vaccination program are all essential to disease prevention. A bio-security program involves a sequence of planning, implementing and control. The aim is to reduce pathogens and prevent their reintroduction.

Outlined below are various key points to a successful bio-security program:
Restrict entry of visitors to the farm. Keep a record of all visitors and their previous farm visits.
Farm workers should visit the youngest flock first, (at the start of the day) and oldest flock at the last.

-Avoid contact with wild birds and backyard poultry.
-Farms should be fenced.
-Keep doors and gates locked at all times.
-No dense foliage around sheds, no roosting site for wild birds
-Provide boots and coveralls for staff and visitors for each shed
-Clean footbaths should be placed at the entrance of each shed. These should be changed regularly.
-Before leaving the farm, clothes should be changed and wash hands and arms.
-The equipment’s used between farms should be thoroughly cleaned and disinfected before use.
-Clean and disinfect all coops, crates and other poultry containers or equipment before and after use
-Provide wheel dips or wheel spraying facilities at the farm entrance and allow only necessary vehicles on site.
-Farm animals other than poultry should be fenced separately and have a different entrance from
the poultry farm enterprise.
– No pet animals should be allowed in or around the poultry housing.
-All farms should have a vermin control plan which includes frequent monitoring of rodent
activity. Adequate supplies of rodent bait must be maintained.
-All houses should be vermin proof. Maintain a strong vector control program for insect,
mammalian and avian vectors.
– The area around the poultry house should be free from vegetation, debris and unused equipment
that could harbor vermin.
-Ensure that feed, water and bedding sources are free from infectious agents
-Clean up feed spills as quickly as possible and fix any leaking feed bins or feed pipes.
-Farms should have toilet and hand washing facilities separate from the poultry house.

-A dedicated changing facility for protective clothing and footwear should be sited at the farm
entrance.
-Provide hand-sanitizing facilities at the entrance to each house.
-Provide well-maintained footbaths at the entrance to each poultry house.
-Clean footwear before using footbath to remove organic material, which could inactivate the
disinfectant.
-Review your biosecurity plan and flock health program, including vaccination protocols, with
veterinarian on a regular basis.
-Sick or dying birds should be sent to a state laboratory for diagnosis. Commercial growers should
contact their flock supervisor.
-Poultry units should be distantly located or well bifurcated from each other.
Provision of separate feed storage facility at units of different species may also be considered.
-Equipment meant for different species of birds should be separate.
-Provision of all-round spray system of disinfectants at the entry of each species units
Exclusive infrastructure facility is essential to rear each species separately and to follow all-in
all-out system
-Proper vaccination schedule must be followed.
-Feed shoulde be regularly analysed for mycotoxins
