Key result
UK approved disinfectants show substantial efficacy data gaps against ASF virus across several classes.
Why the study?
Data on disinfectant susceptibility of African swine fever virus and comparative efficacy of UK approved disinfectants were incomplete and needed review.
This review highlights the efficacy of UK approved disinfectants against African swine fever virus while identifying significant data gaps for certain disinfectant classes.
Informs UK disinfectant approvals for ASF control; leaves open need for field validation against contemporary strains.
A review of African swine fever (ASF) was conducted, including manifestations of disease, its transmission and environmental persistence of ASF virus. Findings on infectious doses of contemporary highly-pathogenic strains isolated from outbreaks in Eastern Europe were included. Published data on disinfectant susceptibility of ASF virus were then compared with similar findings for selected other infectious agents, principally those used in the UK disinfectant approvals tests relating to relevant Disease Orders for the control of notifiable and zoonotic diseases of livestock. These are: swine vesicular disease virus, foot and mouth disease virus, Newcastle disease virus and Salmonella enterica serovar Enteritidis. The comparative data thus obtained, presented in a series of charts, facilitated estimates of efficacy against ASF virus for some UK approved disinfectants when applied at their respective General Orders concentrations. Substantial data gaps were encountered for several disinfectant agents or classes, including peracetic acid, quaternary ammonium compounds and products based on phenols and cresols.

Wales et al. (2021) conducted a review in African swine fever. Disinfectants vs. Other infectious agents was evaluated on Disinfectant efficacy against ASF virus. Estimates of efficacy against African swine fever virus for UK approved disinfectants were facilitated by comparative data, revealing substantial data gaps for several disinfectant classes.
