Yes, but meat that is 100% frozen to the touch and infrared thermometers at well under 32F is still safe. Meat needs to thaw to 40F for bacteria to begin to multiply. A restaurant absolutely needs to cover its bases but at home the chance that food is rotting at ambient 20f is next to none.
Food safety standards require the freezer temperature to he zero or below.

Either way, applying proper judgement is key.
