How Quickly Must Non-Frozen Ready-to-Eat Foods Be Consumed?

Ready-to-eat foods, as the name suggests, are items that can be eaten without additional preparation or cooking. Because of their convenience, they’ve gained popularity in today’s fast-paced world. However, the shelf life of non-frozen ready-to-eat foods can be a concern. So, how quickly should they be consumed to ensure safety and optimal taste?

1. Check the ‘Use By’ or ‘Best Before’ Date

Always start by checking the product’s “Use By” or “Best Before” date. While these dates might sound similar, they have distinct meanings:

  • “Use By” Date: This is a safety indicator. Consuming products after this date might put your health at risk. This label is commonly seen on perishable items.
  • “Best Before” Date: This indicates the product’s optimal quality. While it’s safe to consume the product after this date, its taste, texture, or appearance might be compromised.

2. Refrigerated vs. Room Temperature

Refrigerated Ready-to-Eat Foods:

Examples include deli salads, pre-packaged sandwiches, or certain dairy products.

  • Shelf Life: Typically, they should be consumed within 3-5 days once opened, unless specified otherwise by the manufacturer.

Room Temperature Ready-to-Eat Foods:

Examples include chips, certain bakery items, and some canned goods.

  • Shelf Life: They often last longer, sometimes weeks to months, depending on the product. However, once opened, the shelf life can significantly reduce, often requiring consumption within a week for optimal freshness.

3. High Protein Foods

Ready-to-eat foods high in protein, like deli meats or certain dairy products, can be a breeding ground for bacteria.

  • Shelf Life: Once opened, it’s advisable to consume them within 3-4 days. Some might last a bit longer, but always check for signs of spoilage.

4. Signs of Spoilage

Look out for:

  • Unusual odors
  • Discoloration or mold
  • Changes in texture

If any of these signs are present, discard the product.

5. Storing Correctly

To extend the life of ready-to-eat foods:

  • Refrigerate items that require cold storage promptly.
  • Use airtight containers to store open products.
  • Avoid cross-contamination by using clean utensils.


While non-frozen ready-to-eat foods offer convenience, it’s crucial to ensure they’re consumed within a safe timeframe to avoid health risks. Always check labels, store products correctly, and be vigilant for signs of spoilage to enjoy these foods safely.
