5.2 Proper Food Storage

Proper storage prevents contamination, maintains quality, and ensures food safety.

The FIFO Method

FIFO = First In, First Out

  • Use older products before newer ones
  • When stocking shelves, place new items behind old items
  • Label all foods with receiving or preparation date
  • Check dates regularly and rotate stock

Storage Rules

Height Requirements:

  • Store all food at least 6 inches off the floor
  • Store at least 6 inches away from walls
  • Allows air circulation and easier cleaning

Separation:

  • Store raw meats below ready-to-eat foods (by cooking temperature)
  • Keep chemicals away from food
  • Store food away from cleaning supplies
  • Keep dry goods dry - away from moisture sources

Refrigerator Storage

Temperature: Must maintain 41°F (5°C) or below

Storage Order (top to bottom):

  1. Ready-to-eat foods
  2. Seafood, whole beef/pork (145°F)
  3. Ground meats (155°F)
  4. Raw poultry (165°F)

Best Practices:

  • Don't overcrowd - allows air circulation
  • Store in food-grade, covered containers
  • Date all items
  • Check temperatures daily

Freezer Storage

Temperature: Should be 0°F (-18°C) or below

Freezer Tips:

  • Food quality degrades over time (even frozen)
  • Label with date and contents
  • Don't refreeze thawed food
  • Package properly to prevent freezer burn

Dry Storage

Conditions:

  • Temperature: 50°F to 70°F (10°C to 21°C)
  • Humidity: 50% or lower
  • Clean, dry, well-ventilated

Best Practices:

  • Keep products in original packaging or food-grade containers
  • Store 6 inches off floor
  • Keep away from walls for air circulation
  • Organize by date (FIFO)

Safe Thawing Methods

Four approved thawing methods:

MethodRequirements
RefrigeratorSafest; keep at 41°F or below
Running waterUnder 70°F running water; use within 4 hours
MicrowaveMust cook immediately after
CookingThaw as part of cooking process

Never thaw at room temperature! This allows the outside to enter the danger zone while the inside is still frozen.
