Home Commercial Refrigeration Preventive Maintenance Oklahoma Food Code Cold-Holding Temperature: The 41 °F Rule Learn Oklahoma Food Code Cold-Holding Temperature: The 41 °F Rule What Oklahoma's adopted food code requires for cold holding, how the four-hour rule works, and how refrigeration failures show up on a health inspection. Published 2026-09-07 · By Commercial Refrigeration Oklahoma City Oklahoma has adopted the FDA Food Code for retail food establishments, which requires cold time/temperature control for safety (TCS) foods to be held at 41 °F (5 °C) or below. TCS food between 41 °F and 135 °F for more than four cumulative hours must be discarded. A cooler reading above 41 °F with TCS food inside is a priority violation on a health inspection. The numbers to know Requirement Value Cold holding (TCS food) 41 °F (5 °C) or below Hot holding (TCS food) 135 °F (57 °C) or above The “danger zone” 41 °F – 135 °F Cold food out of temperature, discard after 4 cumulative hours above 41 °F Frozen storage (quality) 0 °F or below Receiving temperature for cold TCS food 41 °F or below (with limited exceptions) The four-hour rule in practice If a walk-in fails and product rises above 41 °F: Under 2 hours: return it to working refrigeration. 2 to 4 hours: use it immediately or cool it back down without delay. Over 4 cumulative hours: discard it. “Cumulative” matters — a unit that drifts warm during every lunch rush is accumulating time. This is why a refrigerated prep table that runs at 45 °F is a frequent write-up even though it “feels cold.” What inspectors check A working thermometer in each cold-holding unit, readable without opening the door where possible. Actual product temperature with the inspector’s probe. Increasingly, temperature logs — a dated record that you monitor and act on. Corrective action : when something is found warm, what did you do? How this ties to your refrigeration A single marginal unit — a dirty condenser, a weak evaporator fan, a torn gasket, a defrost fault — can keep a box hovering at 43–45 °F, safe-feeling but non-compliant. A quarterly maintenance visit with condenser cleaning, gasket checks, and a logged temperature for every unit is the cheapest way to stay clean on inspection. When something does fail, Commercial Refrigeration Oklahoma City leaves a dated temperature log documenting the correction. General summary of adopted food-code requirements.

Cold time/temperature control for safety (TCS) foods must be held at 41 °F (5 °C) or below, per the FDA Food Code adopted by Oklahoma for retail food establishments.

Under the four-hour rule for cold TCS food, product between 41 °F and 135 °F for more than four cumulative hours must be discarded. Between two and four hours it must be used or cooled immediately; under two hours it can be returned to refrigeration. Will a warm cooler fail my health inspection?
