I think this needs thinking about with a view to how food is moved from field to freezer. If it is contaminated by, say, someone in a supermarket then technically it could lie dormant and possibly reactivate. I am not trying to be alarmist and know this is possibly unlikely. I also know that covid 19 hasn’t been around for two years so we do not know if it would survive as long as other corona viruses. I just wanted to mention it in case it can get broadcast so supplier and supermarkets could take it into consideration
