(1) Food must be stored as follows to prevent potential contamination:

(a) Food must be stored in a clean, dry location where it is not exposed to contamination and is at least 6 inches (15 centimeters) above the floor.

(b) Food in packages and working containers may be stored less than 6 inches (15 centimeters) above the floor if it is stored on case lot handling equipment, such as dollies, racks, or pallets.

(c) Pressurized beverage containers; food in waterproof containers, such as bottles or cans in cases; and milk containers in plastic crates may be stored on a floor that is clean and not exposed to floor moisture.

(d) Food may not be stored in toilet rooms; dressing rooms; garbage rooms; mechanical rooms; under sewer lines that are not shielded to intercept potential drips; under leaking water lines, including leaking automatic fire sprinkler heads; under lines on which water has condensed; under open stairwells; or under other sources of contamination.

(e) Food packages must be in good condition and protect the integrity of the contents so that the food is not exposed to adulteration or potential contaminants.

(f) Working containers holding food or food ingredients that are removed from their original packages, such as cooking oils, flour, herbs, potato flakes, salt, spices, and sugar, must be identified with the common name of the food. The labeling must be on the container or on a nondetachable lid. Those containers holding food that can be readily and unmistakably recognized, such as dry pasta, need not be identified.

(g) Packaged food may not be stored in direct contact with water or undrained ice if the food is subject to the entry of water because of the nature of its packaging, wrapping, or container or its positioning in the water or ice.

(h) Whole raw fruits or vegetables, cut raw vegetables such as celery or carrot sticks, cut potatoes, and tofu may be immersed in ice or water that is at a safe temperature.

(i) Raw chicken and raw fish that are received immersed in ice in shipping containers may remain in that condition while in storage awaiting preparation, display, service, or sale.

(2) Packaged and unpackaged food must be protected from cross-contamination by:

(a) cleaning and sanitizing equipment and utensils as specified under ARM 37.110.215;

(b) storing food removed from its original container or package in a clean and sanitized covered container. Covers must be impervious and nonabsorbent, except that clean laundered linens or napkins may be used for lining or covering containers of bread or rolls. Quarters or sides of meat or whole and uncut processed meats may be hung uncovered on clean sanitized hooks if no food product is stored beneath the meat;

(c) cleaning hermetically sealed containers of food of visible soil before opening;

(d) storing damaged, spoiled, or recalled products being held for credit, redemption, or return in designated areas that are separated from food, equipment, utensils, linens, and single-service and single-use articles;

(e) separating fruits and vegetables, before they are washed as specified under ARM 37.110.207(3) from ready-to-eat food;

(f) separating raw animal foods during storage, preparation, holding, and display from raw ready-to-eat food, including other raw animal food such as fish for sushi or molluscan shellfish; other raw ready-to-eat food, such as vegetables; and cooked ready-to-eat food;

(g) separating types of raw animal foods from each other, such as beef, fish, lamb, pork, and poultry, during storage, preparation, holding, and display by any of the following methods:

(i) using separate equipment for each type;

(ii) arranging raw animal products by cooking temperature, with those products requiring lower cooking temperatures at the top and those products requiring higher cooking temperatures at the bottom;

(iii) arranging each type of food in equipment so that cross-contamination of one type with another is prevented; or

(iv) preparing each type of food at different times or in separate areas.

(3) Enough conveniently located refrigeration facilities or effectively insulated facilities must be provided to assure the maintenance of potentially hazardous food at 41 � F (5 � C) during storage except as specified in ARM 37.110.203(61) . Each refrigerated facility storing potentially hazardous food must be provided with a numerically scaled indicating temperature measuring device, accurate to � 3 � F (1.5 � C) , located to measure the air temperature in the warmest part of the facility and located to be easily readable. Recording temperature measuring devices, accurate to � 3 � F (1.5 � C) may be used in lieu of indicating temperature measuring devices.

(4) Frozen food must be kept frozen.

(5) Enough conveniently located hot food storage facilities must be provided to assure the maintenance of food at the required temperature during storage. Each hot food facility storing potentially hazardous food must be provided with a numerically scaled indicating temperature measuring device, accurate to � 3 � F (1.5 � C) located to measure the air temperature in the coolest part of the facility and located to be easily readable. Recording temperature measuring devices, accurate to � 3 � F (1.5 � C) may be used in lieu of indicating thermometers. Where it is impractical to install temperature measuring devices on equipment such as bainmaries, steam tables, steam kettles, heat lamps, cal-rod units, or insulated food transport carriers, a product temperature measuring device must be available and used to check internal food temperature.

(6) The internal temperature throughout potentially hazardous foods requiring hot storage must be 135 � F (57.2 � C) or above except during necessary periods of preparation. Potentially hazardous food to be transported must be held at a temperature of 135 � F (57.2 � C) or above unless maintained in accordance with (3) and (4) of this rule.

(7) In the event of a fire, flood, power outage, or similar event that might result in the contamination of food, or that might prevent potentially hazardous food from being held at required temperatures, the person in charge shall immediately contact the regulatory authority. Upon receiving notice of this occurrence, the regulatory authority shall take whatever action that it deems necessary within its statutory authority to protect the public health.
