I would eat all vacuum-packed raw meat within 7-10 days max. Any longer, and the unaerated environment creates a nasty, toxic taste in the raw meat, which, to me, is a bad sign.
Best way to store raw meat= Store your raw meat carcasses in a room chilled to between 2 to 4 degrees Celsius. It won't freeze, and will very slowly age.
Storing in a fridge with the raw meat exposed to the air is not "unaerated".
In the hot northern Italian summer, I would avoid the fridge for making "high-meat", as it takes so long, and non-RVAFers I know anyway get hysterical over the notion of storing aged, raw meat in the fridge.I would instead, store the raw meat within a plastic container, making sure at least half of the container contained just air, I would then store that container within a much larger empty container, then surround both containers within 2 big plastic bags and then store it all underground(so as to avoid otherwise easy contamination by flies re live maggots infesting the raw meat). I would then air the raw meat for c.2 minutes once a day, until, after 3-4 days max, it was ready for consumption as "high-meat".
