Understanding Food Labeling: Use-By, Best Before, and Sell-By Dates

Many consumers are familiar with yellow stickers on food products, indicating their shelf life. But how critical are these dates? Nutrition experts emphasize the importance of understanding food labels and the implications of consuming items past their marked dates.

The Different Types of Dates on Food Labels

Food products typically carry several date labels, including “use-by,” “best before,” and “sell-by.” Each of these serves a distinct purpose:

• Use-By: This date is critical for safety. Foods must be consumed, cooked, or frozen by this date to avoid health risks. Perishable items like meat, fish, and dairy are particularly susceptible to bacterial growth if consumed after this date.
• Best Before: This indicates quality rather than safety. Products might begin to lose their flavor or texture after this date, but they are generally safe to consume if stored correctly. This label is prevalent on dry, canned, and frozen goods.
• Sell-By: This label primarily guides retailers on how long to display products for sale. It does not indicate safety for consumers.

Misunderstandings about these labels can lead to waste due to unnecessarily throwing away good food or, conversely, risking food-borne illnesses.

Foods to Avoid After the Use-By Date

Health professionals recommend exercising caution with the following items, adhering strictly to their use-by dates:

• Fresh or cooked meat
• Poultry
• Fish
• Soft cheese
• Pâté
• Deli meats
• Fresh ready meals
• Chilled desserts

These foods are notorious for being breeding grounds for dangerous bacteria, especially for vulnerable populations such as pregnant individuals, the elderly, and those with weakened immune systems.

Foods That Can Often Be Consumed After Their Date

In contrast, the following foods may still be safe past their dates if stored correctly:

• Pasta
• Rice
• Cereals
• Flour

If these items are kept in a cool, dry place and stored in airtight containers, they can often be consumed months or even years past their best before dates. Frozen foods also tend to be safe beyond their best before dates, provided they remain continuously frozen.

Considering Food Quality

While it’s essential to be cautious with use-by dates, assessing food quality is equally important for best before items. It is advisable to rely on your senses:

• Check the appearance of the food.
• Smell the product.
• Use common sense to judge its freshness.

However, it’s crucial to discard any food that shows signs of mold or an unusual odor, as these can be indicators of spoilage or food safety issues.

What About Supplements?

Supplements also have expiration dates, which primarily indicate the maximum time for guaranteed potency rather than safety. While many remain effective post-expiration, nutrients may gradually degrade. It is vital to refrain from relying on these products after their dates if they are intended for addressing nutritional deficiencies or specific health concerns.

Be particularly cautious with supplements that contain oils, like fish oil or evening primrose, as they can go rancid if not stored correctly.

Final Recommendations

Understanding food labeling can significantly impact food safety and waste reduction. Always prioritize safety by respecting use-by dates, while also considering the best before dates for food quality. For supplements, adhere to storage guidelines and be cautious of using them past their expiration to maintain efficacy.
