Since September 2020, Germany has experienced the first ever outbreak of African swine
fever (ASF). The first known cases occurred exclusively in wild boar in forest areas in Brandenburg
and Saxony; in July 2021, infected domestic pigs were also confirmed for the first time. As wild boar
are considered the main reservoir for the virus in the European region, an effective interruption of this
infection chain is essential. In particular, the removal and safe disposal of infected carcasses and the
direct disinfection of contaminated, unpaved ground are priorities in this regard. For the disinfection,
highly potent as well as environmentally compatible disinfectants must be used, which are neither
influenced in their effectiveness by the soil condition nor by increased organic contamination. Thus,
in this study, slaked lime, milk of lime and quicklime (1% to 10% solutions) were selected for efficacy
testing against the test virus recommended by the German Veterinary Society (DVG), Modified
Vaccinia Ankara virus (MVAV), and ASF virus (ASFV) in conjunction with six different forest soils
from Saxony in two different soil layers (top soil and mineral soil) each. In summary, 10% of any
tested lime type is able to inactivate both MVAV and ASFV under conditions of high organic load
and independent of the water content of the soil. At least a 4 log reduction of the virus titer in all
tested forest soil types and layers and by all applied lime types was observed. In conclusion, the high
efficacy and suitability of all tested lime products against both viruses and in the presence of high
organic load in forest soil can be confirmed and will help to control ASF spread.
