The use-by date is a label found on packaged food products that indicates the last date by which the food is considered to be at its peak quality and safety. However, many people are unsure about what this date really means and whether it is safe to eat food after it has passed. In this article, we will delve into the world of food safety and explore the concept of use-by dates, including how they are determined, what they mean for consumers, and how long you can safely eat food after the use-by date has expired.
What is the Use-By Date?
The use-by date, also known as the “best if used by” date, is a label that food manufacturers are required to include on their products. This date is determined by the manufacturer based on a variety of factors, including the type of food, the packaging, and the storage conditions. The use-by date is not a safety date, but rather a quality date, meaning that it indicates the last date by which the food is considered to be at its peak quality.
How is the Use-By Date Determined?
The use-by date is typically determined through a process of testing and evaluation. Food manufacturers will conduct sensory testing, which involves tasting and smelling the food to determine its quality and freshness. They will also conduct microbiological testing to determine the level of microbial growth in the food. Based on the results of these tests, the manufacturer will determine the use-by date, which is the last date by which the food is considered to be safe and of high quality.
Factors that Influence the Use-By Date
There are several factors that can influence the use-by date, including:
The type of food: Different types of food have different shelf lives. For example, perishable foods such as meat and dairy products typically have shorter shelf lives than non-perishable foods such as canned goods.
The packaging: The type of packaging used can affect the shelf life of the food. For example, foods that are packaged in airtight containers or bags may have a longer shelf life than foods that are packaged in open containers.
The storage conditions: The way that food is stored can also affect its shelf life. For example, foods that are stored in the refrigerator or freezer may have a longer shelf life than foods that are stored at room temperature.
Can You Eat Food After the Use-By Date?
The answer to this question is not a simple one. While the use-by date is not a safety date, it is still important to follow safe food handling practices to minimize the risk of foodborne illness. It is generally recommended that you do not eat food after the use-by date has expired, as the quality and safety of the food may be compromised. However, if you have stored the food properly and it looks, smells, and tastes okay, it may still be safe to eat.
What Happens to Food After the Use-By Date?
After the use-by date has expired, the quality and safety of the food may begin to decline. This can happen for a variety of reasons, including:
The growth of microorganisms: As food ages, microorganisms such as bacteria, yeast, and mold may begin to grow, which can cause the food to spoil and become unsafe to eat.
The degradation of nutrients: Over time, the nutrients in food may begin to break down, which can affect the nutritional value of the food.
The development of off-flavors and off-odors: As food ages, it may begin to develop off-flavors and off-odors, which can affect the quality and safety of the food.
How to Determine if Food is Still Safe to Eat
If you are unsure whether food is still safe to eat, there are several things you can do to determine its safety. First, check the food for any visible signs of spoilage, such as mold, sliminess, or an off odor. If the food looks, smells, and tastes okay, it may still be safe to eat. However, if you are still unsure, it is always best to err on the side of caution and discard the food.

- Perishable foods such as meat and dairy products: 1-7 days
- Non-perishable foods such as canned goods: 5-10 years
This list is not exhaustive, but it gives you an idea of the varying shelf lives of different types of food. Always check the use-by date and follow safe food handling practices to ensure that the food you eat is safe and of high quality.
What is the difference between a use-by date and a best-by date?
The use-by date and the best-by date are two types of date labels that are often found on food products. While they may seem similar, they have distinct meanings. The use-by date is the last date on which the food product is considered safe to consume. It is usually determined by the food manufacturer and is based on the product’s shelf life, as well as factors such as storage conditions and handling practices. The use-by date is an important indicator of food safety, and consumers should avoid consuming products that are past this date.
In contrast, the best-by date is an indicator of the product’s quality, rather than its safety. It is the date by which the product is expected to retain its optimal flavor, texture, and nutritional value. While consuming a product that is past its best-by date may not pose a health risk, the product may not taste or smell as fresh as it would have before this date. It is worth noting that date labels are not always regulated, and their meanings may vary depending on the country or region. As a result, it is essential for consumers to understand the differences between these date labels and to use their best judgment when deciding whether to consume a product that is past its labeled date.
How do I store food to extend its shelf life and maintain its safety?
Proper food storage is crucial for maintaining the shelf life and safety of food products.
