Like the title says. We use fridges to keep food, so when temperatures are sufficiently low (and below) food decay timer could stop just like in powered-on fridges. Makes so much sense I'm convinced it has already been asked. Alternative could be to allow players to adjust the lower limit temperature where food decay stops in the configs (ecf) files. This could allow having non-powered food caches in the wilderness, or on ship wrecks in space...
