This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Unprecedented SARS-CoV-2 infections in farmed minks raised immediate concerns regarding human health which initiated intensive environmental investigations. Air sampling was performed in infected mink farms, at farm premises and at residential sites. A range of other environmental samples were collected from minks housing units including bedding material. Inside the farms, high levels of SARS-CoV-2 RNA were found in airborne dust, on surfaces, and on various other environmental matrices. This warns for occupational exposure which was substantiated by considerable SARS-CoV-2 RNA concentrations in personal air samples. Dispersion of SARS-CoV-2 to outdoor air was found to be limited and SARS-CoV-2 RNA was not detected in air samples collected beyond farm premises, implying a negligible environmental exposure risk for nearby communities. Our occupational and environmental risk assessment is in line with whole genome sequences analyses showing mink-to-human transmission in farm workers, but no indications for direct zoonotic transmission events to nearby communities.
