Health Inspection Refrigeration Checklist for California Kitchens

Home › Refrigeration Help › Health inspection checklist

Refrigeration is where many health inspection write-ups start: a prep table running at 44°F, a reach-in with no thermometer, pink slime inside the ice machine, a torn gasket, water pooling under the walk-in. Almost all of it is preventable with a few minutes a day. This checklist covers what inspectors look at on your refrigeration under California's Retail Food Code, and the routine that keeps you ready for an unannounced visit.

It is part of our Commercial Refrigeration Help Center, written for Bay Area restaurants, grocers, cafes, bars and convenience stores.

Who inspects, and under which rules

California's Retail Food Code (CalCode, in the Health and Safety Code) is the binding law for restaurants and markets. County environmental health departments enforce it. As the California Department of Public Health puts it, your "local environmental health agency is primarily responsible for enforcing the current California Retail Food Code" (CDPH). The FDA Food Code 2026 is a national model code (FDA Food Code 2026); it shapes good practice, but CalCode is what your inspector cites.

How seriously a problem is scored depends on the county's system. Santa Clara County's environmental health department explains that the 41°F holding requirement "would be a major violation at a temperature reading above 50 degrees F. and minor between 42- and 50-degrees F," and that "Major critical violations do require either closure or immediate correction with a timely follow up inspection" (Santa Clara County DEH). Its current inspection reports still score "Proper hot and cold holding temperatures" in major and minor columns (sample DEH report).

What inspectors check on refrigeration

1. Cold holding at 41°F or below

Potentially hazardous food must be held "at or below 41°F" (CalCode 113996). A few items may be held at or below 45°F, including raw shell eggs, unshucked live molluscan shellfish, and pasteurized milk products in original sealed containers. Expect the inspector to probe food, not only read the unit's display. Prep tables and sandwich units are the usual problem: the top rail holds food in open pans, and it warms fastest when lids stay up or the condenser under the counter is clogged.

2. A thermometer in every unit

"A thermometer shall be provided for each refrigeration unit." It must read the air "in the warmest part of the unit," be "affixed to be readily visible," and read in increments no greater than 2°F (CalCode 114157). The warmest part is usually near the door and high up, not at the back by the coil. A missing or broken thermometer is an easy finding to avoid; keep spares.

3. Frozen food stays frozen, and thawing follows the rules

"Frozen foods shall be stored and displayed in their frozen state unless being thawed" by an approved method (CalCode 114018). Approved methods include thawing under refrigeration at 41°F or below, or fully submerged under running potable water at 70°F or below for no more than two hours (CalCode 114020). A freezer with soft product or a case of meat thawing on a counter will be noticed.

4. Cooling cooked food

Cooked food must cool from 135°F to 70°F within two hours and to 41°F or below within six hours in total (CalCode 114002). Deep stock pots and tightly wrapped hot pans in a walk-in cool slowly and warm everything around them. Shallow pans and ice baths help, and so does a walk-in with healthy refrigeration capacity.

5. Ice machines and ice bins

Ice is food under CalCode (CalCode 113781). Ice makers and bins must be cleaned "at a frequency specified by the manufacturer, or, absent manufacturer specifications, at a frequency necessary to preclude accumulation of soil or mold" (CalCode 114117). Manufacturer intervals differ by brand and model:

• Manitowoc says to descale and sanitize "every six months" (Manitowoc manual).
• Hoshizaki's KM-series cleaning sheet says "at least once a year" (Hoshizaki); check your model's manual.
• Scotsman's CU-series manual says "a minimum of twice per year," and to change water filter cartridges installed more than 6 months (Scotsman manual).

Plumbing counts too. "Liquid waste drain lines shall not pass through an ice machine or ice storage bin" (CalCode 114171), and ice machines, ice bins and walk-ins must drain through indirect waste pipes with an air gap into a floor sink (CalCode 114193). Our ice machine problems guide covers slime, scale and cleaning.

6. Equipment clean and in good repair

CalCode requires equipment to be "kept clean, fully operative, and in good repair" (CalCode 114175). On refrigeration, inspectors notice:

• Gaskets that are torn, brittle, moldy or do not seal. Kolpak recommends cleaning metal surfaces, magnetic door gaskets and door sweep gaskets "frequently with a mild detergent" (Kolpak manual).
• Frost or condensation around a walk-in door. Kolpak says this points to an inoperable door heater or excess moisture.
• Water or ice on the walk-in floor, walls or ceiling. Norlake links it to door gaskets, hardware and doors left open, warning that doors open more than five minutes can leave a film of ice or moisture (Norlake manual). See our refrigeration water leaks page.
• Drips from coils or drain lines onto food or packaging.
• Dirty interiors, rusted shelving and dusty fan guards.

7. Storage habits inside the unit

Good storage keeps food safe and helps the equipment work. Keep food covered and labeled, raw meat below ready-to-eat food, and product off the floor. Do not block the evaporator fans or pack cases against the coil; the cold air has to circulate to reach the thermometer and the food. Avoid overloading a unit beyond what it can hold at temperature.

A daily and weekly refrigeration checklist

These frequencies are a practical routine, not legal requirements. Where a manufacturer gives an interval, it is cited.

Our commercial refrigeration maintenance schedule goes further, task by task.

Warning signs to fix before the inspector sees them

• A unit that reads fine in the morning and 43°F by mid-afternoon. That is usually condenser airflow, a failing fan, or a door or gasket problem, and it will get worse in summer.
• A prep table top rail that will not hold 41°F with the lid open during service.
• Frost that returns on the evaporator coil after defrost.
• Water that keeps coming back under a walk-in or reach-in.
• An ice machine with visible slime, or ice that is cloudy or smells off.

These are repair calls, not cleaning jobs. Our post on regular cooling system inspections for restaurants and grocers explains how routine visits catch them early.

If an inspector finds a temperature problem

Move the food to working refrigeration or follow the inspector's direction on discarding it, document what you did, and get the unit repaired. Keep the service invoice; it shows the problem was corrected. If the failure is sudden or the whole unit is down, use our food safety when refrigeration fails guide for the keep-or-discard rules.

How we help kitchens stay inspection-ready

A preventive maintenance plan puts coil cleaning, gasket and door checks, drain service and ice machine cleaning on a schedule, and a technician flags problems before they become violations. Lotus Thai in San Jose relies on us for preventive maintenance and emergency repair of its HVAC and refrigeration. Every repair carries our 1-year parts and labor warranty. For restaurant owners in San Jose, see our restaurant HVAC and refrigeration service.
