General Food Storage Guidelines
Sequential Flow of Food Storage:
Receive and inspect food.
Label or date-mark food.
Wrap or cover food.
Store in the correct location.
Rotate using FIFO (First-In, First-Out).
Monitor temperatures and discard unsafe food.
Food Labeling Requirements:
Onsite Operations: Any food item removed from its original container must be labeled with the common name of the food or a clear identifier (e.g., bulk hamburger divided into smaller portions).
Retail Operations: Food packaged onsite that is sold for customers to use at home must be labeled appropriately.
Label Content: Labels must clearly identify the food item and include required holding or discard information when applicable.
Date-Marking Rules for Ready-to-Eat TCS Food:
Threshold: Ready-to-eat Time/Temperature Control for Safety (TCS) food must be date-marked if held for longer than .
Maximum Storage Duration: Can be stored for a maximum of when held at an internal temperature of or lower. Day 1 is the day the item was prepared or opened.
Commercial Commercially Processed Foods: If a commercially processed food item has a manufacturer use-by date that is less than from the date the container was opened, the container must be marked with the manufacturer's use-by date.
Combination Dishes: When combining foods with different use-by dates into a single dish, the discard date for the combined dish must be based on the earliest use-by date among all ingredients used (e.g., in chicken salad, the discard date is determined by the oldest TCS ingredient, not the day the salad was mixed).
First-In, First-Out (FIFO) Inventory Rotation:
Check expiration or use-by dates on food items.
Store items with the earliest expiration dates in front of items with later dates.
Use items stored in the front first.
Discard food that has passed its expiration date.
Temperature Guidelines for Storage Units:
Cold TCS Food Internal Temperature: or lower.
Hot TCS Food Internal Temperature: or higher.
Placement within Storage Units: Store meat, poultry, seafood, and dairy in the coldest part of the unit away from the door.
Cold Storage Units: Includes reach-in refrigerators and walk-in refrigerators. Units commonly utilize open wire shelving to ensure optimal cold air circulation; shelving should never be lined with foil or paper.
Maintenance: Defrost freezers regularly to maintain optimal equipment performance.
Preventing Cross-Contamination in Storage:
Cleanliness and Location: Store food in clean, dry areas away from potential environmental contaminants.
Defective Items: Discard any food that is damaged, spoiled, or improperly stored.
Designated Areas: Store food items and supplies strictly in designated food storage spaces, never in restrooms, mechanical rooms, or under unshielded utility lines.
Container Standards: Store food only in durable, leak-proof containers intended for food contact; single-use containers must never be reused.
Covering Rules: Safe storage begins by tightly wrapping or covering all food. Storage arrangement then depends on specific food types and unit capacity.
Recommended Top-to-Bottom Refrigerator Storage Order:
Top Shelf: Ready-to-eat food and food requiring only cooking temperature.
Second Shelf: Seafood (Fish, Shellfish).
Third Shelf: Whole cuts of beef and pork.
Fourth Shelf: Ground meat and ground fish.
Bottom Shelf: Poultry (Whole or ground chicken, turkey, duck) to prevent raw juices from dripping onto other items.
Storing Specific Types of Food
Meat Storage:
Temperature Standard: Receive and store fresh meat at an internal temperature of or lower.
Temperature Measurement: For airtight vacuum-sealed packages (Reduced-Oxygen Packaging / ROP), check temperature by sandwiching the stem of a calibrated thermometer between two sealed packages without puncturing the wrap.
Storage Location: Store immediately after delivery/inspection in its own designated storage unit or the coldest part of the cooler.
Quality Indicators: Piercing reduced-oxygen packaging introduces oxygen, which can cause meat to turn brown. A brown color alone does not necessarily render meat unsafe; however, a rancid odor or sticky, slimy texture indicates spoilage and requires immediate disposal.
Fish and Seafood Storage:
Temperature Standard: Store fresh fish at an internal temperature of or lower.
Packaging: Keep fish in its original packaging or wrap tightly in moisture-proof materials.
Ice Storage: Fresh whole fish may be packed in flaked or crushed ice in self-draining containers; ice must be changed continuously.
Delivery Conditions: Fish may arrive fresh packed on ice or frozen in reduced-oxygen packaging (ROP).
Shellfish Storage:
Shucked Shellfish: Store at an internal temperature of or lower.
Live Shellfish: Store at an air temperature of or lower in their original container.
Shellstock Identification Tags: Do NOT remove the shellstock tag from the container until the final shellfish is removed and served.
Record Keeping: Once the last shellfish is used, retain the corresponding shellstock tag on file in the operation's records for exactly .
Shell Egg Storage:
Air Temperature Standard: Store shell eggs at an ambient air temperature of or lower.
Washing Prohibitions: Do NOT wash shell eggs prior to storage. Washing strips the natural protective coating and allows surface bacteria to enter through shell pores or micro-cracks during handling.
Handling Protocol: Keep shell eggs in refrigerated storage and remove only the quantity required for immediate preparation.
Pasteurized Egg Requirement: Use pasteurized shell eggs or pasteurized liquid egg products when preparing undercooked egg dishes, particularly for high-risk populations.
Poultry Storage:
Temperature Standard: Store fresh poultry at an internal temperature of or lower.
Packaging: If removed from original packaging, place in clean, airtight containers or wrap tightly in airtight material.
Ice-Packed Poultry: Ice-packed poultry may be held in cold storage units as received, provided melting ice is controlled and drained into a drip pan or drained shelf placed underneath to prevent raw poultry juices from leaking across floors and prep areas.
Fresh Produce Storage:
TCS Produce: Refrigerate TCS produce (cut melons, cut tomatoes, and cut leafy greens) at or lower.
Whole Produce: Store whole citrus fruits, squash, eggplants, and root vegetables at .
Dry Storage: Whole citrus and root vegetables can be stored in dry-storage areas in well-ventilated containers.
Pre-Storage Washing: Do NOT wash most produce prior to storage, as excess moisture accelerates mold growth and rot.
Thermometer Rule: Never insert a thermometer stem into intact whole watermelons or pineapples, as piercing intact skin introduces surface contaminants into the fruit core.
Dry Food Storage:
Environment: Store dry food in clean, low-humidity environments.
Container Integrity: Keep flour, cereal, sugar, and grain products stored in airtight, food-grade containers with tight-fitting lids.
Pest Inspection: Check packaging and containers for signs of pest damage or infestation prior to opening.
Humidity Impacts: High relative humidity causes hygroscopic dry goods (such as salt or sugar) to absorb moisture, leading to clumping and quality degradation.
Food Preparation Practices
General Food Preparation Practices:
Cross-Contamination & Time-Temp Abuse Reduction: Clean and sanitize all workstations, utensils, and equipment before use. Remove only as much TCS food from the cooler as can be prepped in a short time frame; return prepped portions immediately to refrigeration or begin cooking promptly.
Honest Presentation: Present food to guests without misleading additions or misrepresentations (e.g., using food/color additives improperly to alter apparent freshness).
Corrective Actions: Discard food that has been contaminated or rendered unsafe, unless it can be safely reconditioned according to approved safety parameters.
Approved Thawing Methods for TCS Food:
Refrigeration: Thaw in a cooler at an ambient temperature maintaining the food at or lower.
Running Water: Submerge food completely under clean, running drinkable water at or lower. Water flow must be strong enough to agitate and float off loose food particles into the sink drain; use ice if needed to keep running water temperatures at or below .
Microwave: Thaw in a microwave oven only if the food item will be cooked immediately following the thawing process.
Cooking: Thaw food directly as part of an uninterrupted cooking procedure (e.g., cooking frozen hamburger patties directly on a grill).
ROP Frozen Fish Thawing: Reduced-Oxygen Packaged (ROP) frozen fish must remain frozen until ready for use and must be removed from its packaging before thawing under refrigeration or immediately after thawing under running water.
Prepping Specific Foods:
Meat, Poultry, and Seafood: Clean and sanitize all prep tools and surfaces. Prepare raw meats separately from fresh produce. Remove only immediate working quantities from cold storage.
Salads Containing TCS Ingredients (Chicken, Tuna, Egg, Pasta, Potato): Prepare in small batches. Use leftover TCS ingredients only if they were cooked, held, cooled, and stored safely for no more than at or lower. Chill all ingredients prior to mixing.
Eggs and Egg Mixtures: Handle pooled eggs (multiple eggs cracked and combined into one container) with extra care. Cook pooled eggs immediately or store them at or lower. Clean and sanitize all pooled egg bowls between batches. Use pasteurized eggs when serving raw or undercooked egg dishes or when serving high-risk populations.
Batters and Breading: Mix batters in small batches and store in cold refrigeration. Discard breading or batter that comes into contact with raw meat, poultry, or seafood. Cook breaded items thoroughly.
Fresh Juice: Treat fresh juice according to an approved HACCP plan (e.g., pasteurization) or affix a mandatory FDA warning label. Operations serving high-risk populations must NEVER serve unpasteurized juice.
Produce Handling: Keep raw, unwashed produce separated from ready-to-eat foods. Wash produce thoroughly under running drinkable water prior to cutting, combining, or serving. Refrigerate cut melons, cut tomatoes, and cut leafy greens at or lower.
Ice Safety: Make ice exclusively from safe, drinkable (potable) water. Never reuse ice that was used to chill food or beverage containers as an ingredient in food or drink. Store dedicated ice scoops outside the ice machine in a clean, sanitized container.
Special Preparation Practices Requiring a Regulatory Variance:
A official variance (and typically a formal HACCP plan) approved by the local regulatory authority is required for:
Packaging fresh juice on-site for later sale without a warning label.
Smoking food as a method of food preservation (rather than for flavor).
Using food additives or adding components (such as vinegar) to alter or preserve food so that it no longer requires time/temperature control.
Curing food.
Custom-processing animals for personal use.
Packaging food using Reduced-Oxygen Packaging (ROP) methods (including sous-vide, cook-chill, and vacuum packaging).
Sprouting seeds or beans.
Operating a live shellfish display tank used to store shellfish that will be served to guests.
Cooking Guidelines & Standards
Minimum Internal Cooking Temperatures and Holding Times:
Poultry (Whole or ground chicken, turkey, duck): for .
Ground Meat (Beef, pork, or other meat): for .
Food from Plants (Fruits, vegetables, grains, legumes for hot holding): with no minimum holding time.
Microwave Cooking (Meat, seafood, poultry, eggs): Must be cooked to an internal temperature of . Food must be covered, rotated or stirred halfway through heating, allowed to stand covered for at least after cooking to equalize temperature, and checked in multiple places.
General Cooking Guidelines:
Recipe Verification: Specify exact cooking times and target minimum internal temperatures in standardized recipes.
Thermometer Execution: Insert calibrated food thermometers into the thickest section of the item. Take multiple readings in various areas, especially for irregularly shaped items.
Equipment Usage: Avoid overloading cooking equipment, which lowers unit heat and prevents food from reaching safe internal temperatures. Allow cooking units to recover temperature between batches.
Consumer Advisories:
Disclosure: Clear notice must be provided on menus identifying any items that are served raw or undercooked (e.g., using asterisks linking to a footnote).
Remind/Advise: Explicitly inform guests about the elevated risk of foodborne illness associated with consuming raw or undercooked meats, poultry, seafood, shellfish, or eggs.
Children's Menu Prohibition: Never offer raw or undercooked meat, poultry, seafood, or eggs on a children's menu.
High-Risk Populations (Hospitals, Nursing Homes, Daycare Centers):
Operations serving high-risk populations must NEVER serve:
Raw seed sprouts.
Raw or undercooked eggs, meat, poultry, or seafood.
Unpasteurized milk or juice.
Packaged foods (e.g., frozen vegetables) that have not been fully cooked according to manufacturer instructions.
Partial Cooking (Non-Continuous Cooking) Requirements:
Initial Heat Limit: Do not heat food for longer than during initial preparation.
Immediate Cooling: Cool food immediately after initial heating according to approved cooling procedures.
Cold Storage: Freeze or refrigerate partially cooked food immediately after cooling ( or lower).
Final Heating: Heat food to its required minimum internal cooking temperature before serving.
Secondary Cooling: Cool food again if it will not be served immediately or transferred to hot holding.
Documentation: Maintain written procedures on site outlining initial heating times, cooling protocols, and responsible monitoring personnel.
Cooling and Reheating Food
Two-Stage Cooling Process for TCS Food:
Total Allowable Time: Cooling TCS food must occur within a maximum total duration of .
Stage 1: Cool food from down to within the first .
Stage 2: Cool food from down to or lower within the remaining .
Failure Correction: If food does not reach within the initial , it must be reheated to for and the cooling process restarted from the beginning.
Factors Affecting Cooling Rate:
Thickness and density of the food item.
Volume and size of the food mass.
Type and material of storage container (thin stainless steel transfers heat significantly faster than thick plastic).
Approved Cooling Methods:
Ice-water bath: Place food containers into a sink or basin filled with ice and water, stirring frequently.
Ice paddle: Stir hot liquid foods using hollow plastic paddles filled with water and frozen.
Blast or tumble chiller: Use specialized equipment that circulates cold air or chilled water around food containers.
Ice or cold water as an ingredient: Cook food with less liquid, adding clean ice or cold water at the end of cooking.
Container Placement: Divide large batches into small, shallow metal pans. Loosely cover containers during cooling; seal tightly only once food reaches .
Reheating Standards:
Reheating for Immediate Service: Food prepared and cooled on-site can be reheated to any temperature if served immediately to an individual guest.
Reheating TCS Food for Hot Holding: Must be reheated to an internal temperature of for at least . The entire reheating process must take less than .
Commercially Processed RTE Food: Reheat commercially packaged ready-to-eat food to an internal temperature of at least .
Equipment Rule: NEVER use hot-holding equipment (such as steam tables or soup warmers) to reheat food. Reheat food rapidly on cooking equipment first, then transfer to holding units.
