The food safety website says the danger zone for chilled food is between 40°F and 140°F. Even if frozen food has begun to thaw, it can be safely refrozen if it remains below 40°F or still has ice crystals on it. However, the website actually suggests you avoid storing food outdoors.

Generally speaking, you should be okay to store food outside as long as the temperature is somewhere between 30 and 40 degrees. Anything colder and food will freeze (which isn't an issue if you're trying to keep frozen food frozen) and anything warmer may lead to the growth of harmful bacteria.How cold does it have to be to keep food frozen?

The most vulnerable food products in your fridge are those with high water content such as dairy, meat, poultry, eggs, and seafood.Will food freeze at 32 degrees?
