Hi Cameron...a belated lang may yer lum reek! :-)) I would suggest a week in the fridge, or months, up to six or so, in the freezer. I have been making stock forever, not with all of those precautions, and in 50 years have never made any of us ill. What you will find, rather, is a loss of flavour, certainly that after sitting in the fridge that long, more or less sealed, or not. In the freezer, however, we have stocks that have the same taste as when they were first frozen, 5 or 6 months later. I have even removed a jar of chicken stock, removed some, and re-frozen the rest, with no appreciable difference. Dunno if the same result could be had from the fridge! Have fun with your new toy! I bought a used VitaMix from the Sally Ann thrift shop, and have been grinding our own wheat berries, and rye for flour, which Marie has been turning into great bread!
