The purpose of disinfection is to eliminate the pathogens that are transmitted by the source of infection in the external environment in order to cut off the route of transmission and prevent the spread of the disease.
The main methods of disinfection are:
(1) Mechanical elimination is mainly through cleaning, scrubbing, ventilation, filtration and other mechanical methods to eliminate pathogens. This method is an ordinary and commonly used method, but it cannot achieve the purpose of thorough disinfection. As an auxiliary method, it must cooperate with other disinfection methods.
(2) The physical disinfection method uses sunlight, ultraviolet rays, drying, high temperature and other methods to kill bacteria and viruses.
(3) Chemical disinfection is a method of killing pathogens with chemical drugs, and is most commonly used in epidemic prevention. The choice of disinfectant should consider the broad spectrum of bactericidal effect, low effective concentration, quick action, good effect; harmless to humans and livestock, stable in nature, easily soluble in water, not easily affected by organic matter and other physical and chemical factors; easy to use, inexpensive and easy to use Promotion; odorless, odorless, no damage to the items being sterilized; less residue or side effects after use. According to the chemical composition of the disinfectant can be divided into: 1 phenolic disinfectant, there are carbolic acid, Lai Su Er, Ke Lilin, bacterial enemy, agricultural welfare, etc.; 2 aldehyde disinfectant, formaldehyde solution, glutaraldehyde and so on; 3 Alkali disinfectants, including sodium hydroxide, lime (calcium oxide), and ash, etc.; 4 Disinfectants containing chlorine, bleaching powder, calcium hypochlorite, triads, sodium dichloroisocyanurate, chloramines (chlorine Yaming), etc.; 5 peroxide disinfection drugs, hydrogen peroxide, peracetic acid, potassium permanganate, ozone, etc.; 6 quaternary ammonium salt disinfectants, there are benzalkonium, chlorhexidine, diclofen, disinfection net and so on.
(4) Biological disinfection method In the veterinary epidemic prevention practice, this method is commonly used to contaminate the accumulated feces. Fermentation with thermophilic bacteria produces heat of up to 70°C. After 1 to 2 months, virus and bacteria (spore) can be produced. Except for), parasite eggs and other pathogens kill, both to achieve the purpose of disinfection, but also maintained the fertilizer effect. However, this Act does not apply to diseases caused by spore pathogens such as anthrax and emphysema. The feces of such diseases should be incinerated or buried deeply.
(5) Implementation of disinfection 1 Regular disinfection: 2 to 4 times a year, at least once in spring and autumn. All utensils in the beef barn should be disinfected once a month. The following drugs can be used to disinfect the cowshed and manure urine: 5% to 10% hot alkali water, 3% caustic soda, 3% to 5% lecithin, or stinky water solution spray disinfection, with 20% lime milk Paint the walls. Feeding management tools, cattle pens, cattle beds, etc. are 5% to 10% hot alkali water, or 3% caustic soda solution, or 3% to 5% susu, or disinfected with an aqueous stinking solution, 2~6 after disinfection. Hours, rinse the trough and cattle bed with fresh water before placing the cows. Clean the playground, remove the weeds, and disinfect with 5% to 10% hot alkaline water or lime. 2 Temporary disinfection: After detecting and removing tuberculosis, brucellosis or other diseased cattle from the herd, the cowsheds, utensils and playground shall be temporarily disinfected. When an abortion occurs in a diseased cattle, the flow products and the contaminated sites and utensils must be thoroughly disinfected. The excreta of diseased cattle should be accumulated in a place far away from the cowshed, and they can be used as fertilizer after conducting biothermic fermentation. The maternity room conducts a large disinfection once a month, and the delivery room conducts one disinfection before and after the production of the live cow. All cattle who have died of or died of a disease such as brucellosis or tuberculosis must be dissected or slaughtered at the designated location under the guidance of a veterinary epidemic prevention officer. The bodies should be disposed of in accordance with the relevant national regulations. After the treatment is completed, the staff, venues and utensils on the site are thoroughly disinfected. It is strictly forbidden to dissect cows suspected of anthrax death, etc., and dispose of them in accordance with relevant state regulations.
