How Long Will Food Last in the Fridge: A Comprehensive Guide
When it comes to food safety, proper storage is key. Knowing how long different types of food can last in the fridge can help you reduce waste, save money, and most importantly, keep you and your family safe from foodborne illnesses. In this guide, we will explore the recommended storage times for various foods in the refrigerator.
Understanding Food Shelf Life
Understanding food shelf life is essential for maintaining food safety. While the "best by" or "use by" dates on food packaging can provide guidance, they are not set in stone. It's important to use your senses - such as sight, smell, and taste - to determine if a food is still safe to eat.
Factors Affecting Food Spoilage
Several factors can affect how long food will last in the fridge, including:
- Temperature: The ideal temperature for a refrigerator is 40°F (4°C) or below.
- Humidity: Some foods require high humidity, while others do better in low humidity.
- Packaging: Properly sealed containers or bags can help extend the shelf life of food.
- Freshness: The fresher the food is when it's stored, the longer it will last.

Dairy Products
