A food service establishment shall have adequate refrigeration and hot holding and storage facilities for the proper storage, transportation, display, and service of potentially hazardous foods. Specific refrigeration and hot holding and storage needs shall be based upon the menu, number of meals, frequency of delivery, and preparation in advance of service.
(a) Refrigeration. Refrigerators shall be capable of maintaining and shall maintain potentially hazardous foods at or below 41 degrees Fahrenheit (5 degrees Celsius) at all times. Food preparation procedures should be conducted so that refrigerators are opened on only a limited basis.
(1) Shelving. Shelving for walk-in and reach-in refrigeration units shall be made of food grade material that is smooth and easily cleanable.
(2) Air circulation and cooling ability. Air circulation within refrigeration units shall not be obstructed and shall allow for an even and consistent flow of cold air throughout the units. Fans circulating air within refrigeration units shall be kept clean, dust free, and in working condition. Gaskets shall be kept clean and intact and shall be replaced as needed so that refrigeration units may maintain food at required temperatures.
(3) Thermometers. Refrigeration units shall have numerically scaled or digital indicating thermometers, calibrated to be accurate to (+) or (-) 2 degrees Fahrenheit. The thermometer shall be placed to measure air temperature in the warmest part of the unit.
(4) Placement. Refrigeration units, unless specified by the manufacturer and designed for such use, shall not be located directly adjacent to cooking equipment or other high heat producing equipment which may tax the cooling system's operation.
(5) Walk-in refrigerator floors. Walk-in refrigerator floors that are water-flushed for cleaning or that receive discharge of liquid waste or excessive melt water, shall be non-absorbent and sloped to drain.
(6) Outdoor walk-in refrigerators. Refrigerators located outdoors shall be kept clean, locked, secure, and in operating condition, and shall not permit entry or harborage of pests.
(b) Hot holding. Hot holding and storage equipment shall be capable of maintaining and shall maintain potentially hazardous foods at or above 140 degrees Fahrenheit (60 degrees Celsius) at all times.
(1) Thermometers. Hot holding units shall have numerically scaled or digital indicating thermometers, calibrated to be accurate to (+) or (-) 2 degrees. The thermometer shall be placed to measure air temperature in the coolest part of the unit.
