This is Turtle.
1] If meat is vacuumed packed like Edwin said or frozen in water . they could be good for up to 3 or 4 years. If just in a Ziplock bag sealed up. Ity will last maybe a few months.2] a chest type freezer full to the top will go up to 7 days before the food or meat becomes bad. Then it will stay frozen enought to refreeze up to 4 days with the lide not opened and letting heat in it. We had a power outage of 7 days here a few years ago and the power staied off for about 4 days before i bought a Generator and put power back on the Chest type freezer and my freezer staied froze & good for that 4 days.
