| description | SARS-CoV-2 contaminated items in the cold chain becomes a threat to public health, therefore the effective and safe sterilization method fit for the low temperature is needed. Ultraviolet is an effective sterilization method while its effect on SARS-CoV-2 under low-temperature environment is unclear. In this research, the sterilization effect of high-intensity ultraviolet-C (HIUVC) irradiation against SARS-CoV-2 and
Staphylococcus aureus
on different carriers at 4 °C and − 20 °C was investigated. The results showed that dose of 15.3 mJ/cm
2
achieved more than 3 log reduction of SARS-CoV-2 on gauze at 4 °C and − 20 °C. The vulnerability of coronavirus to HIUVC under − 20 °C was not significantly different than those under 4 °C. Four models including Weibull, biphasic, log-linear tail and log linear were used to fit the survival curves of SARS-CoV-2 and
Staphylococcus aureus
. The biphasic model fitted best with R
2
ranging from 0.9325 to 0.9878. Moreover, the HIUVC sterilization correlation between SARS-CoV-2 and
Staphylococcus aureus
was established. This paper provides data support for the employment of HIUVC under low-temperature environment. Also, it provides a method of using
Staphylococcus aureus
as a marker to evaluate the sterilization effect of cold chain sterilization equipment.
