1. Disinfect cages
Want disinfection efficiency, should apply the correct technical process and selection of appropriate disinfectants. Below is a guide of Doctor. Nguyen Thi Hoa Ly, Center for Veterinary Hygiene Inspection Central II - Department of Veterinary Medicine

Along with vaccination, disinfection will contribute to limiting the spread of pandemic influenza.  When choosing a disinfectant, it is necessary to consider the following factors:
* Characteristics pathogens: each type of bacteria, fungi, viruses have learned the characteristics of different microorganisms and sterilize each drug has unique mechanism of action, because pathogens can be sensitive to these drugs but re resistant to other disinfectants.
For example, disinfectants amonium group of type 4 virus is sensitive to hydrophilic groups, but very bad effects with lipophilic group virus (herpec virus, influenza virus).
* Objects and disinfection conditions: the conditions have not translated but not translated or are forced to kill livestock and destroy identified, the disinfected pens to reduce the number of germs and prevent outbreaks.
At the same time, the sanitizer is also guaranteed not to adversely affect animal health, so should choose pesticides do not cause irritation, although non-toxic weak antiseptic properties. But the object is empty cages, vehicles, rubbish dumps or the outbreak required the death and destruction of dangerous animals, they must choose the correct drug has strong antiseptic properties, such as chlorine, phenol, glutaraldehyde to kill germs completely.
* Drug concentration and exposure time: depending on drug and disinfected objects, but to pathogens and the concentration of different exposure time. For example, to disinfect the eggs incubated in potassium permanganate and formol come 20-25 minutes, but to disinfect storage of animal products when translated to 24 hours.
For avian flu, in the antidotal antiseptic to note:
- Safety Assurance: Farmers, who work in the outbreak should be worn labor protection: masks, gloves, protective clothing and rubber boots. Sort compact tools for easy decontamination, antidotal. Since the outbreak of protection to the locker, poison disinfected clothes and cleaning.
- No bird buried waste near water sources like rivers, wells, the water table is low.
- Bury the birds in large numbers certainly do not avoid pollution, so it contains chicken in sealed plastic bag or covered with plastic sheets on the hole, spraying disinfectant before burial, backfill and compaction depth.
The camp has no services, in areas under threat:
- To minimize the move into the camp.
- In a poultry cages containing disinfectants in compressed air, aerosol spray form of the entire ceiling, wall, walls, air, to disinfect cages. Levels of 1.2 to 1.5 volume lit/100m3 cages (cage volume = length x width x height), once daily at 10 am to 14g.
The drugs used BKC (benzakonium chloride solution) ratio 1 / 400, BKA 1 / 200 and GPC-8 ratio 1 / 500.
- Handling of commercial eggs: eggs placed on the trays in the room contained, closed. Dose: 10g KMnO4, formaldehyde 35ml/m3 air.
Method: for KMnO4 in a porcelain or ceramic tray with a little water, a closed room, poured from the tray from formaldehyde. Closed, place the sea warning (because the gas mixture is very toxic) after at least 24g to open my door to open.
- Hole disinfected: periodically every two days instead of antiseptic drugs in the pits to the camp and between areas, the breeding range. Chlorine chemicals used by 5-6%, 2-4% glutaraldehyde.
- Other subjects such as transportation, distributed garbage collection handled daily by 5-6% chlorine, 2-4% glutaraldehyde, lime.
These places are translated:
+ Death and poultry waste disposal: how many dead poultry prior to processing, such as carbon dioxide injection gas, causing asphyxiation, but the virus is the causative agent for human use; to ensure the safety of veterinary personnel y, when transporting waste treatment method should be chosen come formol.
Very toxic gas inhalation, workers need to have labor protection, masks, gloves, when poured into formol solution of potassium permanganate to pour slowly and look into the pot, to avoid the nose, face to face airflow fly.
+ Make the drop dead duck:
- Depending on the number of ducks were more or less, make the bamboo strapless columns, each crank is locked up from 200 to 400 children, the height crank from 0.5 to 0.8 m. Dig out a hole from 0.4 to 0.5 m, each placed in a pot hole or porcelain bowl.
- Herded ducks in the evening. Use nylon canvas cover.
- For every bowl crockery already in place 50-60g potassium permanganate, add 100ml water, pour slowly into 200 ml formol solution of potassium permanganate.
- After 10 - 20 minutes completely dead poultry.
+ Death ducks, chickens, quail cage:
- If the cage has no ceiling, use plastic canvas covered the entire range of each cage.
- If a bare cage, closed the barn, the surrounding cover.
- The cage volume: length x width x height.
- Sauna formol: dosage: 10g KMnO4, formaldehyde 35ml/m3 air.
- Method: custom size cage, put 2-3 or porcelain pot porcelain volume 8-10 liters, Republic of KMnO4 with KMnO4/hai proportional part of the country, a closed room, poured slowly ( by side pots) on formaldehyde in suspension. Closed, place the sea warning (because it is toxic vapor mixture) after the bird died off, opening the door.
- Use the chicken into a large plastic bag, tied mouth, carried to the place of destruction.
- Burial: 3-4m deep pit, depending on the length width to the number of birds destroyed. If the chicken in the bag did not contain a layer of nylon plastic to cover the entire surface of the hole, pour chicken body down, spray disinfectant (lime, chlorine or crezine) and fill the earth surface, the distance from the corpses to the surface at least 1 to 1.5 m of land, soil tightly compressed.
Note: if you do not kill chickens come by formol, before being transported for destruction of chlorine disinfectant spray to 3-5% on the cover.
Compost:
- Burning: collecting all feces, garbage, solid waste, food waste, bedding material and cheap material for burning barn in the background.
- Buried: lime waste is sprinkled or sprayed chloramine, Ca (OCl) 25% then burying ground at least 0.5 - 1m.
For the empty barn, ranch land around:
- Spray disinfectant on the entire surface, walls, troughs, drinking troughs, ceilings, roof barn .- Pesticides are sprayed to ensure wetting the entire surface to be disinfected (80 - 120ml/m2 area) and sprayed in the direction from high to low.
- After washing the 24g water, dried and sterilized again 2. Before announcing the end of translation, raising the entire area must be disinfected antidotal.
- The use of disinfectants: chlorine 5-6%, 2-4% glutaraldehyde, 3-5% ophenylphenol.

- The area around the barn to be cleared, waste collection instrument for destruction, then spray disinfectant as above.
