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.

Either way, applying proper judgement is key.
