Organizing Your Fridge

Keeping your fridge organized helps stop germs from spreading. It also keeps food fresh longer.

Proper organization can reduce the chance of cross-contamination in your fridge. This keeps your family safe.

Storage Zones

Your fridge has different zones with different temperatures. Use these zones to store food safely.

Keep raw meat on the bottom shelf to stop drips from contaminating other foods. Store ready-to-eat foods higher up.

  • Bottom shelf: Raw meat, poultry, and fish
  • Middle shelves: Dairy products and leftovers
  • Top shelves: Ready-to-eat foods and drinks
  • Fridge door: Condiments and sauces
  • Crisper drawers: Fruits and vegetables

Labeling Containers

Labeling helps you know what is inside each container. It also shows when the food was stored.

Use clear labels with the food name and date. This helps you use food before it goes bad.

  • Write the food name clearly
  • Include the date you stored the food
  • Use waterproof labels or masking tape
  • Replace labels if they get dirty or wet

Proper Food Storage

Keeping food safe in your fridge helps stop germs from spreading. Proper storage lowers the risk of cross-contamination.

Organize your fridge so foods do not touch or drip onto each other. This keeps harmful bacteria away.

Raw Meat And Seafood

Store raw meat and seafood separately from other foods. Keep them in sealed containers to avoid leaks.

Place these items on the lowest shelf. This stops their juices from dripping onto other foods below.

  • Use airtight containers or sealed plastic bags
  • Label packages with the date
  • Keep raw meat and seafood on the bottom shelf
  • Clean spills immediately

Dairy Products

Keep dairy products in their original containers. Store them on shelves, not in the fridge door, for a stable temperature.

Avoid placing dairy near raw meat or seafood. This helps prevent bacteria from spreading.

  • Store milk, cheese, and yogurt on middle or upper shelves
  • Keep containers tightly closed
  • Check expiration dates regularly

Fruits And Vegetables

Wash fruits and vegetables before storing them. Use the fridge drawers designed for produce to keep them fresh.

Do not store fruits and vegetables near raw meat or seafood. This reduces the chance of contamination.

  • Keep produce in clean, dry drawers or containers
  • Separate fruits and vegetables if needed
  • Remove spoiled items quickly

Temperature Control

Keeping the fridge at the right temperature helps stop bacteria from growing. This prevents food from spoiling and lowers the risk of cross-contamination.

Good temperature control keeps food safe and fresh for longer. It is a key step in preventing germs from spreading inside the fridge.

Ideal Fridge Temperature

The fridge should be set to the right temperature to keep food safe. The ideal temperature slows down bacteria growth and keeps food fresh.

Most experts say the fridge should stay at or below 40°F (4°C). This temperature helps stop harmful bacteria from multiplying.

  • Set fridge temperature at 37°F to 40°F (3°C to 4°C)
  • Keep freezer at 0°F (-18°C) or below
  • Avoid placing hot food directly in the fridge

Regular Temperature Checks

Check the fridge temperature often to make sure it stays in the safe range. This helps catch problems early before food spoils.

Use a fridge thermometer to get an accurate reading. Write down the temperature to track any changes over time.

  • Place the thermometer in the middle shelf
  • Check temperature at least once a week
  • Adjust fridge settings if temperature is too high
  • Clean the fridge regularly to keep it working well

Knowing what each label means helps you decide if food is safe or should be thrown out.

  • Use By:Eat before this date for safety.
  • Best Before:Food is best quality before this date.
