Poultry Biosecurity Flashcards
Preventing the introduction of a disease agent onto a farm
Bio-exclusion
Prevent ing the spread of a di sease agent on a farm
Bio-confinement
in
poultry production is the most effective and economic way to control poultry diseases.
Biosecurity
Components of biosecurity and their meanings.
Bio-exclusion and Bio-confinement
What must be the chronological order of buildings in a poultry farm to avoid diseases.
Brooder > Grower > Finisher
The distance of buildings in a chicken farm.
Chick to Grower shed = 50-100 feet
Grower to Layer shed = 100 meter
The 6 Biosecurity of Poultry Farms
- Geographical location of Poultry farms.
- Structural layout of the poultry farms and building.
- Potential sources of infection and operational flow on the farm.
- Cleaning and disinfection protocols for poultry.
- Water quality in poultry houses.
- Biosecurity aspects that are specific to the different production systems.
In poultry farms, you must consider the prevailing winds. The wind must hit the brooders first, then growers, and finishers. True or False.
True
Keep away from other Poultry and
Processing plant. True or False
True
What must be provided in the entrance of each building in a poultry farm.
Hygiene Lock
The buildings should be secure from wild birds, rodents
and insects that may be carriers of _, _, and other diseases.
Salmonella, Mycoplasma
This must be included in the hygiene lock to wash and
disinfect hands and clean clothes and footwear.
Wash basin
There must be a clear separation between _ and _ section.
Clean, Dirty
The entrance to the buildings should be made of solid and cleanable surfaces. True or False.
True
Buildings should be as far away as possible from roads, along which
poultry, feed or litter are transported. True or False.
True
3 parts of a hygiene lock
Entrance Door
Green Zone (Clean)
Amber Zone
Red Zone (Dirty)
Exit Door
A first rule is that diseases must be kept outside. The second important
biosecurity rule is that diseases that have been brought inside, should be spread outside. True or False
False. Should stay inside.
What do you call is the pool of water that vehicles go through to wah the wheels? How about to wash the foot?
Wheel Bath, Foot Bath
6 Potential sources of infection and operational flow on the farm
- Introduction through humans
- Introduction through equipment and vehicles
- Feed
- Birds
- Disposal of dead birds and litter
- Vermin
The 3 diseases that can be transmitted into the chickens are:
Salmonella, Mycoplasma, Campylobacter
There are many ways in which micro-organisms can be introduced into farms. Therefore, they should disinfect and if possible, take a shower. On the other hand, farm personnels should change clothes footwear between houses. True or False.
True
The frequency of taking a bath when working in a poultry farm.
8 or more times
Vaccination instruments and other equipment should not be taken inside the house without first being cleaned and disinfected. True or False.
True
Trucks that transport poultry, eggs or feed can go back and forth inside and outside of the poultry farm. True or False.
False. Must be cleaned, washed and
disinfected each time before loading.
Feeds can be contaminated with pathogens (e.g. Salmonella) through ingredients, during production, delivery or storage. Therefore, a feed sample must be kept from each delivery batch until the end of the production cycle. True or False.
True
Layer pullets that have been reared on the same premises and exposed to infection can become carriers of some diseases not existing on the layer farms and introduce new pathogens to a production site. True or False.
False. on separate premises
How often must dead birds be collected, if there is any? Why?
Twice a day. Because they are a source of infection that other chickens will pick on.
Mice, rats, flies, insects, and beetles are some example of vermin’s that can spread diseases. True or False.
True
Mice and rats are transmitters of what pathogens?
Salmonella and Campylobacter
Feed, manure and rubbish should be kept outside the house. True or False
True
Distance of poultry farms from rural areas should be _.
1 km
The length of time when a chemical is left on a surface.
Contact time
Cleaning that is effective with the use of what equipment either with or without chemical detergents?
Pressure hose
Disinfectant act instantly. True or False.
False. They do not act instantly and must have enough contact time to take effect.
A disinfectant intended for decontamination of buildings should work well in the presence of a moderate amount of organic matter. It should be compatible with soap or detergents, safe to building materials, and relatively non-toxic to man and animals. True or False.
True.
A disinfectant must be readily soluble even in hard water, effective against a wide variety of infectious agents (e.g., viruses, bacteria, fungi, protozoa), free from objectionable or lingering odor, readily available, and inexpensive. True or False.
True
After cleaning, it should be disinfection to have the maximum effect of disinfectants. True or False.
True. Since organic matters can greatly reduce the effect of disinfectants.
Disinfectants in Poultry Farms
- Phenolic compounds (e.g., cresol, orthophenyl-phenol, and corthobenzyl-
parachlophenol) - Organic iodine combinations /iodophores (e.g.,povidone-iodine)
- Quaternary ammonium compounds/salts (e.g., benzalkonium chloride, benzathonium chloride, cetyipyridinium chloride)
- Hypochlorite (e.g., chlorine)
- Combinations of organic acids, organic biocides, and surfactants
