Understanding food shelf life is essential for maintaining food safety, reducing waste, and saving money. This guide will help you decode the often confusing labels and signs that indicate when food should be discarded.

What is Food Shelf Life?

Food shelf life refers to the length of time a food product remains safe to eat and retains its desired sensory, chemical, physical, and microbiological characteristics. It varies widely depending on the type of food, storage conditions, and packaging.

Key Terms to Know

Term	Meaning
Best Before Date	Indicates when the product is expected to be at its best quality, not a safety deadline.
Use By Date	The last date recommended for the safe consumption of perishable foods.
Sell By Date	A guide for retailers to manage stock, not a safety indicator for consumers.

Factors Affecting Shelf Life

Storage Temperature: Cooler temperatures generally extend shelf life.
Packaging: Vacuum-sealed or airtight packaging can slow spoilage.
Food Type: Perishable items like dairy and meat spoil faster than dry goods.
Exposure to Air and Moisture: Can accelerate deterioration.

How to Tell if Food Has Gone Bad

Visual Signs: Mold, discoloration, or unusual textures.
Smell: Off or sour odors.
Taste: If safe to sample, a strange or off taste indicates spoilage.

Avoid cross-contamination.
Freeze items if you won’t use them soon.
Keep your refrigerator clean and organized.
