(3)The manure in the pigsty should be thoroughly removed, and the pig manure scattered in the yard should be collected and stored for sealed fermentation or incineration.

Highly pathogenic porcine blue ear disease virus has poor survival ability in external environment. As long as disinfection measures are appropriate, disinfectants commonly used in pig production practice, such as aldehydes, chlorine-containing disinfectants, phenols, oxidants, alkalis, etc., can kill viruses in the environment. It is better to use the following disinfectants to disinfect the environment of the house:

(1)Aldehyde disinfectants: formaldehyde, polyformaldehyde, etc., among which formaldehyde fumigation is the most commonly used. Closed pens can be fumigated by adding 7~21 grams of potassium permanganate per cubic meter to 14~42 ml of formalin. When fumigating, the room temperature should generally not be lower than 15℃, the relative humidity should be 60%-80%, potassium permanganate can be added to the container first, then formalin, closed doors and windows for more than 7 hours can achieve the purpose of disinfection, and then open the doors and windows ventilation, eliminate residual smell.

(2)Chlorine-containing disinfectants: including inorganic chlorine-containing disinfectants and organic chlorine-containing disinfectants. The disinfection effect depends on the content of available chlorine. The higher the content, the stronger the disinfection ability. 5% bleach solution can be sprayed on animal housing, cages, feeding troughs and vehicles for disinfection.

(3)Alkali preparations: mainly sodium hydroxide and quicklime, etc., most of the sodium hydroxide preparations for disinfection are crude lye containing 94% sodium hydroxide, which are often heated into 1%-2% aqueous solution, which are used for disinfection of poultry house floors, walls, sports grounds and dirt contaminated by viruses, as well as for disinfection of slaughterhouses, food factories and other floors and transportation vehicles. Spray for 6-12 hours and rinse with clean water.
