African Swine fever (ASF) is an acute, virulent, and highly contagious infectious disease caused by the African swine fever virus (ASFV) infecting domestic pigs and wild boars. It is listed as a statutory report by the World Organization for Animal Health (OIE) Animal diseases, China has also listed it as a type of animal epidemics to focus on prevention.
Acidic electrolyzed water (abbreviation: AEW, with hypochlorous acid as the main component, pH 5.0–6.5) is prepared with a commercially available "electrolyzed water generator", and its effective chlorine concentration (FCC) is 5–140 ppm, the researcher The effect of acidic electrolyzed water in reducing the titers of African swine fever virus (ASFV) and avian influenza virus (AIV) was tested under different organic concentration conditions. The results are as follows:
Under low-level organic pollution conditions, AEW with FCC≥40ppm is effective for ASFV; under high-level organic pollution conditions, AEW with FCC≥80ppm is effective for ASFV.
Under low-concentration organic pollution conditions, AEW with FCC≥60ppm has an inhibitory effect on AIV; under high-concentration organic pollution conditions, AEW with FCC≥100ppm has an inhibitory effect on AIV.
Based on the above research data, we recommend that under the conditions of low and high levels of organic pollution, when using acidic electrolyzed water for routine disinfection in livestock and poultry breeding, the recommended concentrations are as follows: for ASFV disinfection, 50 ppm and 100 ppm; for AIV Disinfection, 75 ppm and 125 ppm, respectively.
Acidic electrolyzed water has a strong killing effect on African swine fever virus and can be used for disinfection of livestock and poultry farms. At the same time, we recommend that when using acidic electrolyzed water as a biological control measure for livestock and poultry farms, the presence of organic matter should be minimized.
