How to disinfect the farm correctly

Disinfection of farms is very important in aquaculture. However, in the process of disinfection, some farmers are not completely disinfected or fail to achieve the expected results because of unreasonable disinfectant selection and improper disinfection methods. In order to kill pathogens in time, effectively cut off the route of transmission and control the epidemic situation, disinfection operations should pay attention to the following three aspects. \x0d\ 1。 Correct selection of disinfectants \x0d\ Farmers should use disinfectants recommended by local veterinary epidemic prevention departments according to different disinfection objects, requirements and environmental conditions. Check the label and instructions when purchasing to determine whether it is a qualified disinfectant approved by the veterinary drug supervision department for production and sales, and it is within the validity period. At the same time, it is considered whether the disinfectant has the advantages of low price, easy solubility in water, no residual poison, no damage to the sterilized object, relatively stable in air, convenient use, broad spectrum, rapid and efficient disinfection of epidemic diseases. When in use, a scientific preparation method is adopted as needed. According to the instructions, the actual concentration, suitable temperature and solvent selection should be prepared, and the drugs should be prepared now, not for a long time; Some disinfectants are prepared and used many times at a time, but the content of effective components should be determined first, and then prepared and used according to the determination results. \x0d\ Second, the disinfection method should be appropriate \x0d\ Choose an efficient and feasible disinfection method according to different disinfection environments, disinfection objects and types of disinfected objects. Generally, it is carried out by spraying, soaking, drinking water and fumigation. In addition, there are flame, high temperature, cooking, biological fermentation and other disinfection methods. Scientific disinfection procedures should be designed in production, and compatibility taboos should be avoided when two or more drugs are used together. When disinfection is carried out, the diluted disinfectant should be directly used for disinfection. After a certain period of time, the dirt on the disinfected object should be removed, especially the organic matter should be thoroughly cleaned. Repeat disinfection with disinfectant again, so that the operation effect will be better. Long-term use of disinfectants should be cross-used, so as to avoid high-dose or long-term use of the same disinfectant, otherwise it is easy to produce drug resistance, and even lead to environmental pollution and drug residues in animal products exceeding the standard. Therefore, it is necessary to cross-use drugs according to specific conditions in production. \x0d\ III。 Pay attention to preventive disinfection \x0d\ Preventive disinfection can play a multiplier role in disease prevention and control. Regular disinfection should be carried out according to local conditions. Although there is no epidemic sometimes, if the environment is not disinfected and purified in time, the pathogens in the environment will accumulate more and more. When the number and virulence of pathogens reach a certain level, it is easy to cause an epidemic. At the same time, there will be a blind spot of disinfection, which will also pose a threat through the media such as air, wild birds, mice, surrounding environment and trees. Therefore, we should always choose different disinfectants and disinfection methods for vehicles, people and articles, pens and utensils. According to the different disinfection objects.
