Low risk of SARS-CoV-2 transmission via fomite, even in cold-chain.

ABSTRACT:

Background

Countries continue to debate the need for decontamination of cold-chain food packaging to reduce possible SARS-CoV-2 fomite transmission among workers. While laboratory-based studies demonstrate persistence of SARS-CoV-2 on surfaces, the likelihood of fomite-mediated transmission under real-life conditions is uncertain.

Methods

Using a quantitative risk assessment model, we simulated in a frozen food packaging facility 1) SARS-CoV-2 fomite-mediated infection risks following worker exposure to contaminated plastic packaging; and 2) reductions in these risks attributed to masking, handwashing, and vaccination.

Findings

In a representative facility with no specific interventions, SARS-CoV-2 infection risk to a susceptible worker from contact with contaminated
