Food safety is a top priority, and at FOODS.EDU.VN, we understand the confusion surrounding expiration dates. Discover whether it’s safe to consume products past their “best by,” “sell by,” or “use by” dates, and learn how to identify signs of spoilage. Learn about food storage, shelf life, and food waste reduction.
1. Understanding Food Expiration Dates: Quality vs. Safety
Many people believe that food expiration dates are strict indicators of when a product becomes unsafe to eat. However, the reality is more nuanced. Expiration dates, particularly “best by” dates, are primarily about food quality rather than safety. This means that a product past its “best by” date may not taste as fresh or have the same texture, but it is likely still safe to consume if stored properly. According to Janilyn Hutchings, a food scientist and certified professional in food safety at StateFoodSafety, “Food dating is more about food quality than food safety. With the exception of baby formula, the food dating system is not government-regulated or standardized, so the dates printed on most items are actually suggestions from the manufacturer to help you know when the product is at its best quality.”
Jennifer Kaplan, a former food systems instructor at the Culinary Institute of America, adds that expiration dates are “a manufacturer’s vague estimate of when the product is at its ‘freshest.’ Many foods will still be good to eat days, weeks, or months after those dates.”
1.1. The Role of Manufacturers and Regulations
It’s important to note that, with the exception of infant formula, expiration dates are not federally regulated. Manufacturers determine these dates based on their own assessments of product quality and shelf life. This lack of standardization can lead to confusion, as different manufacturers may use different criteria for setting expiration dates. The USDA provides guidance on date labeling to help consumers and manufacturers understand the different types of dates used on food products.
1.2. Key Differences: “Best By,” “Sell By,” and “Use By” Dates
Understanding the different types of date labels is crucial for making informed decisions about food safety and quality:
| Date Label | Meaning | Consumer Interpretation |
|---|---|---|
| Best By | Indicates when a product will have the best flavor or quality. | The product is safe to eat after this date, but its quality may decline. Ideal for items where peak flavor and texture are desired. |
| Sell By | Informs retailers how long to display the product for sale. | Consumers can still safely consume the product after this date. Primarily for inventory management in stores. |
| Use By | Suggests the last date for peak quality. Required on infant formula to ensure nutritional content meets standards. | Use by dates are more indicative of safety; consume before this date for the best quality and safety. For infant formula, adhere strictly to the date. |

1.3. The Importance of Proper Food Storage
Proper food storage is essential for extending the shelf life of food and minimizing the risk of spoilage. Factors such as temperature, humidity, and exposure to air can all affect how long food remains safe and of good quality.
Here are some general guidelines for storing food properly:
- Refrigerate perishable foods promptly: Foods that require refrigeration, such as meat, poultry, fish, dairy products, and cooked leftovers, should be refrigerated within two hours of purchase or preparation.
- Store food at the correct temperature: Refrigerators should be set to 40°F (4°C) or below, and freezers should be set to 0°F (-18°C) or below.
- Use airtight containers: Store food in airtight containers to prevent exposure to air and moisture, which can cause spoilage.
- Label and date food: Labeling food with the date it was purchased or prepared can help you keep track of how long it has been stored and ensure that you use it before it spoils.

2. Identifying Foods Whose Expiration Dates Matter Most
While many expiration dates are simply indicators of quality, some foods require closer attention due to the potential risks associated with spoilage. These include:
- Fresh Fruits and Vegetables: These items are prone to mold growth and bacterial contamination.
- Dairy Products: Milk, cheese, and yogurt can spoil quickly and harbor harmful bacteria.
- Meat and Poultry: Raw meat and poultry can contain pathogens that cause foodborne illness.
- Eggs: Eggs can become contaminated with Salmonella bacteria.
2.1. Risks of Consuming Spoiled Food
Eating spoiled food can lead to various health problems, ranging from mild discomfort to serious illness. Common symptoms of foodborne illness include nausea, vomiting, diarrhea, abdominal cramps, and fever. In severe cases, foodborne illness can lead to dehydration, hospitalization, or even death.

2.2. Infant Formula: A Special Case
Infant formula is the one product where expiration dates are strictly regulated by the U.S. Department of Agriculture (USDA). Past the expiration date, there’s no guarantee that the formula matches the nutrition information on the packaging. Using expired infant formula can deprive a baby of essential nutrients and potentially harm their health.
2.3. Nutritional Value Over Time
Even if a food remains safe to eat after its expiration date, its nutritional value may decline over time. Vitamins, minerals, and other nutrients can degrade, reducing the health benefits of the food. This is particularly important for foods that are major sources of essential nutrients.
3. Recognizing Signs of Spoilage: More Than Just the Date
Relying solely on expiration dates can be misleading. It’s essential to use your senses to detect signs of spoilage, regardless of what the date label says.
Dr. Luiza Petre, a cardiologist who also specializes in nutrition, weight management, and wellness, advises, “Always watch for warning signs like odors, flavors, and colors that don’t look, smell, or taste right, and discard immediately, regardless of the date on the label.”
3.1. The Sniff Test and Visual Inspection
The “sniff test” remains a reliable way to assess food safety. If a food has an unusual or unpleasant odor, it is likely spoiled and should be discarded. Visual inspection is also important. Look for signs of mold growth, discoloration, or changes in texture.
3.2. Common Signs of Spoilage
| Food Type | Signs of Spoilage |
|---|---|
| Milk | Sour odor, curdled texture, discoloration. |
| Meat | Slimy texture, foul odor, discoloration (gray or green). |
| Poultry | Slimy texture, foul odor, discoloration (gray or yellow). |
| Fish | Fishy odor, slimy texture, discoloration. |
| Eggs | Foul odor, runny white, discolored yolk. |
| Bread | Mold growth, stale texture. |
| Fruits & Vegetables | Soft spots, mold growth, discoloration, foul odor. |
3.3. Proper Storage and Packaging
Food that isn’t properly stored or packaged can spoil even before its expiration date. Make sure to store food in airtight containers and at the correct temperature to prevent spoilage. Damaged packaging can also compromise food safety, so inspect food packages carefully before purchasing or using them.

4. What to Do With Food Past Its Expiration Date
If you’ve determined that a food is still safe to eat after its expiration date, there are several ways to use it:
- Cook it: Cooking can kill harmful bacteria and improve the taste and texture of slightly stale food.
- Use it in recipes: Incorporate slightly past-its-prime ingredients into recipes where their texture or flavor won’t be as noticeable.
- Donate it: According to the USDA, you can even donate food after the expiration date has passed.
4.1. Non-Perishables: A Longer Shelf Life
Non-perishable foods, such as canned goods, dried beans, and pasta, can often be kept and consumed well past their expiration dates. However, their taste, quality, and nutrition may be compromised over time.
4.2. Food Banks and Donations
Food banks often accept donations of food that is past its expiration date, as long as it is still safe to eat. However, it’s important to check with the food bank to see what their specific policies are.
4.3. Composting as a Sustainable Option
If a food is no longer safe to eat, composting is a sustainable way to dispose of it. Composting reduces food waste and creates nutrient-rich soil that can be used to grow plants.
5. Deciphering Different Date-Labeling Phrases
The variety of date-labeling phrases can be confusing. Here’s a breakdown of what each one means:
5.1. ‘Best By’ Date: Quality Assurance
According to Hutchings, “The ‘best by’ date gives the consumer a deadline for when the product will have the best flavor or quality.” Products past their “best by” dates should still be safe to eat (as long there aren’t any signs of spoilage), but they might taste a little less than fresh since they’re the manufacturer’s best estimate of when their product will still be the best quality.
5.2. ‘Sell By’ Date: Retail Guidance
In contrast, “sell by” dates are really more for stores than consumers. According to the USDA, “sell by” dates tell grocery stores and other retailers how long the product should be on display and available for sale. It’s also not a measure of safety, and most products should be good even after the “sell by” date has passed.
5.3. ‘Use By’ Date: Peak Quality
“The ‘use by’ date tells the consumer the last date the product will be at its peak quality,” Hutchings says. And according to the USDA, “use by” dates are only a measure of safety when they’re used on infant formula. All other products should still be safe to eat.

7. Addressing Common Misconceptions About Food Safety
There are many misconceptions about food safety that can lead to unnecessary food waste. Here are a few common myths and the facts behind them:
- Myth: The “5-second rule” is safe. Fact: Bacteria can transfer to food within seconds of it falling on the floor.
- Myth: Washing meat and poultry is necessary. Fact: Washing meat and poultry can spread bacteria around your kitchen.
- Myth: Freezing food kills bacteria. Fact: Freezing food only slows down bacterial growth.
7.1. Debunking the “5-Second Rule”
The “5-second rule” is a popular myth that suggests it’s safe to eat food that has been dropped on the floor as long as you pick it up within five seconds. However, studies have shown that bacteria can transfer to food within seconds of it coming into contact with a contaminated surface.
7.2. The Truth About Washing Meat and Poultry
Washing meat and poultry is not necessary and can actually be harmful. Washing can spread bacteria around your kitchen, increasing the risk of cross-contamination. The best way to ensure that meat and poultry are safe to eat is to cook them to the correct internal temperature.
7.3. Freezing and Bacteria: What You Need to Know
Freezing food slows down bacterial growth but does not kill bacteria. When food is thawed, bacteria can start to multiply again. It’s important to handle thawed food properly and cook it to the correct internal temperature to kill any harmful bacteria.
