Abstract


Meat processing plants have been at the center of the SARS-CoV-2 pandemic. There are several
 factors that contribute to the persistence of SARS-CoV-2 in meat processing plants and one of the
factors is the formation of a multi-species biofilm with virus. Biofilm can act as a reservoir in
protecting, harboring, and dispersing SARS-CoV-2 from biofilm to the meat processing facility
environment. We used Murine Hepatitis Virus (MHV) as a surrogate for SARS-CoV-2 virus and
 meat processing facility drain samples to develop mixed-species biofilms on commonly found
materials in processing facilities (Stainless-Steel (SS), PVC and tiles). The results showed that
MHV was able to integrate into the environmental biofilm and survived for a period of 5 days at
7°C. There was no significate difference between the viral-environmental biofilm biovolumes
developed on different materials SS, PVC, and tiles. There was a 2-fold increase in the virus-
environmental biofilm biovolume when compared to environmental biofilm by itself. These results
indicate a complex virus-environmental biofilm interaction which is providing enhanced
 protection for the survival of viral particles with the environmental biofilm community......
