Laboratory research using in vitro, ex vivo and in vivo models has been accelerated to understand the pathogenesis of SARS-CoV-2 infection. However, such experimental research involving SARS-CoV-2 is restricted to biocontainment/safety level-3 (BSL-3) settings, due to the high pathogenicity of this virus. Since many of the downstream analyses of SARS-CoV-2-infected biological samples need to be conducted in a non-BSL3 setting, it is important to ensure that the samples are fully decontaminated and safe for subsequent analysis. Here, we report the effectiveness of standard procedures used to fix cells and tissues for pathological analysis, including 2% or 4% paraformaldehyde, 50%-70% ethanol, 10% neutral buffered formalin and ultrafiltration using membranes with a molecular weight cut-off (MWCO) ranging from 3 to 30 kDa, for inactivating or eliminating SARS-CoV-2. We validated these methods in experimental laboratory samples, such as viral inoculum in cell culture media, SARS-CoV-2 infected host cells and animal tissue lysates. We found that 15 minutes' treatment of viral inoculum (10(5) plaque-forming units; PFU) or SARS-CoV-2 infected cells with paraformaldehyde or 70% ethanol resulted in complete inactivation of the virus. The treatment of infected hamster lung tissues with 10% neutral buffered formalin also fully inactivated the virus. However, only 3 kDa ultracentrifuge filter was effective in eliminating the virus to an undetectable limit in the filtrate. Our validated methods are useful for decontaminating biological samples to reduce infection risk and safe handling in BSL2 facilities.
