Is food safe in refrigerator at 49 degrees for 12 hours?

The safe temperature range for refrigerating food is between 34°F and 39°F. At a temperature of 49°F, food can enter the "danger zone," where bacteria multiply rapidly and can cause foodborne illness. Keeping food at this temperature for 12 hours is unsafe and could lead to spoilage and potential health risks. It's best to discard any perishable foods that have been left in the refrigerator at 49°F for such an extended period.
