Understanding Food Date Labels: Best Before vs. Use By
The most critical aspect of determining whether fruit is safe to eat is understanding the difference between a "use by" date and a "best before" date. While both appear on packaging, they serve very different purposes related to food safety versus quality. The European Food Safety Authority and other agencies emphasize that misinterpreting these labels is a major cause of preventable food waste.
Use By Dates
A use-by date is about food safety, not quality. This is the most important date to remember for highly perishable items. You should never eat, cook, or freeze food after its use-by date, even if it looks and smells fine. Harmful bacteria can grow on these products that you cannot see, smell, or taste, posing a significant risk of foodborne illness. In general, most fresh fruit does not carry a 'use by' date unless it is pre-packaged and highly perishable, such as a fruit salad or a smoothie pack. For these products, strict adherence to the label is necessary.
Best Before Dates
The "best before" date, sometimes labeled as BBE (best before end), is about quality, not safety. Foods with this label are still safe to eat after the specified date, but their flavor, texture, or freshness may be diminished. Many fruits fall into this category, especially those with longer shelf lives. For fruits with a 'best before' date, your senses are a valuable tool. Look, smell, and even taste (in small amounts) to determine if the quality is still acceptable. Examples include apples, citrus fruits, and dried fruits.
The “Sniff Test” and Other Sensory Clues
For most raw fruits, relying on sensory cues is the most reliable way to judge freshness. This is often referred to as the "sniff test," but involves more than just smell.
Visual Indicators:
- Mold: Any visible mold means it's time to toss the fruit. Soft fruits like berries and peaches with mold should be discarded entirely, as the mold spores and toxins can permeate the entire fruit. For hard fruits like apples or firm melons, you can sometimes cut away a large margin (at least one inch) around a small spot of mold, but this is done at your own risk.
- Bruises and Soft Spots: Small, localized bruises are generally fine. Simply cut them out. However, if soft spots are widespread and the fruit is becoming mushy, this is a sign of decomposition and bacterial growth.
- Color Changes: A change in color can indicate spoilage. For example, fresh-cut fruit turning brown is not a safety issue but a sign of oxidation, while a full fruit developing dark or black spots may indicate rot.
Tactile Indicators:
- Texture: Excessively soft, slimy, or wrinkled fruit is typically past its prime. Good fruit is firm and plump.
- Juice Leakage: If a fruit is leaking juice and becoming wet and sticky on the outside, spoilage bacteria are likely at work.
Olfactory Indicators:
- Smell: A foul, sour, or fermented smell is a strong indicator that the fruit has gone bad and should not be eaten.
Fruit spoilage by type
Different fruits spoil at different rates and in different ways. Here is a comparison to help you make an informed decision:
| Feature | Soft Fruits (e.g., Berries, Peaches) | Hard Fruits (e.g., Apples, Pears) | Citrus Fruits (e.g., Oranges, Lemons) |
|---|---|---|---|
| Shelf Life | Very short (3-7 days) | Long (several weeks to months) | Long (several weeks) |
| Primary Spoilage Indicator | Mold, mushiness, weeping juice | Soft spots, skin blemishes, wrinkles | Mold, dried-out texture, loss of flavor |
| Safety After Date | Do not eat once past 'use by' or when mold appears due to high moisture content. | Usually safe to eat past 'best before' if firm; cut away any bruised or moldy spots. | Safe to eat past 'best before' as long as there is no mold and the skin is intact. |
| Risk of Illness | Higher due to rapid spread of mold and bacteria. | Lower; visible spoilage is often contained on the surface. | Lower; acidic environment inhibits some bacterial growth, but mold can still pose a risk. |
Guidelines for Handling Fruit Safely at Home
To maximize the life of your fruit and minimize waste, proper handling and storage are crucial.
- Buy Smart: Choose fruits without bruises, cuts, or damaged skin, as these are entry points for bacteria.
- Wash Thoroughly: Always wash fruit under running water right before you eat, cut, or cook it, even if you plan to peel it.
- Separate Safely: Keep fresh produce separate from raw meat, poultry, and seafood in your shopping cart, grocery bags, and refrigerator.
- Refrigerate Properly: For most perishable fruits, refrigeration is key. Maintain your fridge temperature at or below 40°F (5°C).
- Cut and Store: Refrigerate all cut or peeled fruit promptly. Discard any cut fruit left at room temperature for more than 4 hours.
- Know When to Freeze: Freezing can extend the life of many fruits indefinitely, though quality may decline over time. Freeze fruit before the 'use by' date to pause the spoilage process.
Conclusion: A Common Sense Approach
Ultimately, whether you can safely eat fruit after its labeled date depends on a careful assessment of its condition, not just the number on the package. Pay close attention to the specific labeling—'use by' means a hard deadline for safety, whereas 'best before' indicates a peak quality guideline. For the majority of unpackaged, raw fruits, your senses are the best tools. Inspect for mold, changes in texture, and unpleasant odors. By understanding these distinctions and practicing proper storage, you can reduce food waste and protect your health.
