The person in charge of the Provincial Animal Husbandry Bureau told the reporter that farmers should pay attention to weather forecast and public opinion. Areas that are threatened by floods should transfer livestock and poultry to higher safety zones as soon as possible and discharge them in a timely manner. The transfer of livestock and poultry is often closer to the residents because of the site constraints, and the farming density is increased. This requires the strengthening of the disinfection of livestock and poultry sites and their surrounding environment, and the prevention of all kinds of livestock and poultry infectious diseases, especially the occurrence of major disease epidemics.
After the disaster, farmers need to thoroughly clean and sterilize the housing and surrounding environment. Disinfection of collapsed sheds focuses on in situ disinfection of dead animals and sheds; disinfects farms that can be used continuously, cleans large-scale farms regularly, disinfects them regularly with chemical drugs, and maintains cleanliness and environmental sanitation. Prevent the intrusion of wild animals and eliminate mice and mosquitoes. For small-scale farms and free-ranging households, the focus is on regular cleaning of the pens and handling of excreta and keeping them clean. If diseases occur, they must be disinfected with chemical disinfecting drugs; in addition to routine disinfection, the reconstructed pens should be sterilized. After the disaster, the number of disinfections should be increased according to the prevalence of the disease, and appropriate disinfection drugs should be selected.
No slaughter, no food, no sale, no transshipment of dead animals is allowed. The livestock and poultry that have died of unexplained causes must be diagnosed in a timely manner in accordance with the regulations. If a major animal epidemic is found, more efforts must be made to intensify disinfection and prevention and control, and report the situation in a timely manner. The simple and effective method of harmless treatment is deep-buried. The deep-buried area should be high-pit and the depth of the pit should be more than 2 meters. After the body is put into the pit, sprinkle lime or disinfectant to cover the thick soil. Where conditions permit, incineration can be carried out, or directly into a detoxification treatment tank. The deep-buried treatment of animal corpses in the disaster area requires attention to the following points:
1, according to the size of the death of animal handling, ready for working tools, such as trucks, tractors, excavators, bulldozers, animal carcass shipping bags (best seal) and so on. Transport vehicles should prevent leakage of body fluids. The underlying contact surface can be considered to be covered with plastic film. The contact surface should be repeatedly cleaned and disinfected. Animal carcasses must not be transported with food or live animals.
2. The burial site should be covered with enough soil to cover it. The soil permeability is not high and there is a certain distance (100 meters to 150 meters) from rivers, lakes, ponds, wells and other bodies of water. It is easy for animals to arrive and avoid public sights (distance). The residential area is at least 100 meters away from the place where the floodwaters are often washed away. In certain cases, animals dying at the farm may consider burial on site. Scattered small animals (such as chickens, etc.) can be buried under the roots and other places.
3. The volume of the pit body is generally 2 to 4 times the volume of the animal carcass. Pit body width is generally not less than 1.2 meters, the depth is generally 2 meters, the length must be able to accommodate all dead animals. The bottom of the pit should be relatively flat. If multiple buried pits are required, the pit spacing should not be less than 1 meter.
4, buried method. For large animals, medium animals, or small animals, such as poultry and pigs, if the number of dead bodies is small, place the bodies in the pits and cover them with soil. The thickness of the cover soil shall not be less than 0.7 meters. When the number of small animal carcasses is large, they can be buried in layers. The thickness of each layer of the carcass is generally not more than 0.3 meters, and the middle covering is at least 0.3 meters. The layers are buried in sequence, and the thickness of the final covering soil layer shall not be less than 0.7 meters. During the burying process, the cover soil must not be compacted so as not to affect the natural decay. When conditions permit, quicklime should be laid on the bottom of the pit and on the carcass. After the body is buried, wild animals should be prevented from digging.
5. Participants should pay attention to safety protection. Wear protective clothing, rubber gloves, masks (masks), goggles and rubber boots when working. Pay attention to cleaning and disinfection, receive health monitoring, and check with the health department as soon as possible.
