How Long Is Milk Good After Sell by Date?
Milk is generally good for up to 7 days after the sell-by date if it remains unopened.
However, if the milk has been opened, it is typically good for about 3 days after the sell-by date.
It is important to note that these dates may vary by manufacturer and are not necessarily expiration dates.
To determine if milk is spoiled, look for signs such as a sour smell, changes in color or consistency, and a sour or acidic taste.
Consuming spoiled milk can lead to gastrointestinal issues and should be avoided.
Proper storage in the refrigerator, away from the door, can help extend the shelf life of milk.
Alternatively, milk can also be frozen to prevent waste and prolong its usability.
Quick Tips and Facts:
1. Contrary to popular belief, milk can actually remain consumable for up to a week after its sell-by date if stored correctly.
2. The sell-by date on a carton of milk is primarily meant for the retailers, indicating the last day the product should be displayed for sale. It does not necessarily indicate the last day the milk is safe to consume.
3. An unopened carton of milk can often remain good beyond its sell-by date if refrigerated at the correct temperature (around 40°F or 4°C). Factors such as the milk’s storage conditions and the specific microbiological state at the time of purchase influence its shelf life.
4. If the milk has been opened and smells sour or exhibits a chunky texture, it is likely spoiled and should not be consumed, regardless of the sell-by date.
5. Ultra-high temperature (UHT) milk, also known as long-life milk, has undergone a sterilization process that extends its shelf life dramatically. Some UHT milk products can remain safe and palatable for several months or even up to a year when unopened, surpassing sell-by dates.
Milk Expiration Dates And Their Variations
When it comes to milk, many consumers rely on the dates printed on the packaging to determine its freshness and safety. However, it is important to understand that the United States Department of Agriculture’s (USDA) Food Safety and Inspection Service does not require dairy manufacturers to label or date their products.
Despite this, you may still come across four types of dates on milk:
- Best if Used By/Before: This refers to the date when the milk is at its peak quality.
- Sell-By: This indicates the last date at which retailers can sell the product.
- Use-By: This is the last recommended date for consuming the milk while it is still at its best quality.
- Freeze-By: This signifies the date by which the milk should be frozen to extend its shelf life effectively.
It’s crucial to note that these dates can vary from one manufacturer to another and they may not actually represent the milk’s expiration.
Signs Of Spoilage In Milk
Determining if milk is still good after its sell-by date involves examining several indicators of spoilage. The most distinguishable sign is the sour smell. If the milk emits an off-putting odor, it is likely no longer suitable for consumption. Additionally, keep an eye out for any changes in color. Spoiled milk can display variations ranging from a slightly yellowish tinge to a more profound discoloration.
Another indicator of spoilage is the milk’s consistency. Fresh milk should have a smooth, creamy texture. If you notice any clumps, lumps, or curdled bits in the liquid, it is best to discard the milk immediately. Finally, taste can provide valuable information. If milk tastes sour or acidic, it has likely started to spoil and should not be consumed.
The Shelf Life Of Opened And Unopened Milk
The shelf life of milk is dependent on whether it is opened or remains sealed. Once opened, a carton of milk typically remains fresh for about three days beyond the expiration date. However, this can vary based on storage conditions. Ideally, unopened milk can generally remain safe for consumption for up to seven days after the expiration date.
It is important to consider that individual factors such as temperature fluctuations and proper storage practices can greatly affect the freshness of milk. Therefore, it is crucial to check for signs of spoilage before consuming milk past its expiration date.

Differences Between Pasteurized And Unpasteurized Milk
When evaluating the shelf life of milk, pasteurization status is a crucial factor to consider. Pasteurized milk, which has undergone a heating process to eliminate bacteria and extend its shelf life, typically has a longer expiration date compared to unpasteurized or raw milk.
Raw milk, which has not been heat-treated or pasteurized, is known for its shorter shelf life and higher risk of bacterial contamination. It is vital to adhere to the expiration date when consuming raw milk and store it properly to prevent spoilage.
To summarize:
- Pasteurized milk has a longer shelf life due to the heating process it undergoes.
- Raw milk has a shorter shelf life and poses a higher risk of bacterial contamination.
- Adhering to the expiration date and proper storage practices are essential for raw milk consumption.
Identifying Spoiled Milk Through Visual Cues
In addition to the smell, color, and taste, visual cues can also help identify spoiled milk. One common indicator is the presence of mold, which can range in color from black to blue. If you notice any mold growth on the milk or around the rim of the container, it is a clear indication that the milk is no longer safe to consume.
Furthermore, changes in the milk’s consistency should be taken seriously. Fresh milk should have a smooth, homogeneous texture. If you observe any clumps, chunks, or lumps in the milk, it is a sign of spoilage. These visual cues provide valuable insights into the milk’s freshness and safety.
- Look for mold growth on the milk or around the rim of the container
- Check for clumps, chunks, or lumps in the milk
Remember: If you notice any of these visual cues, it is best to avoid consuming the spoiled milk.
Proper Storage Methods To Extend Milk’s Freshness
To ensure that milk stays fresh for as long as possible, proper storage methods are crucial. It is recommended to store milk on the shelf toward the back of the refrigerator, where the temperature remains consistently cold. Storing milk in the refrigerator door exposes it to temperature fluctuations, affecting its shelf life and quality.
Additionally, it is essential to check for signs of spoilage before consuming milk past its expiration date. This includes inspecting the smell, color, consistency, and taste. If any of these indicators suggest spoilage, it is best to dispose of the milk.
For those looking to extend the shelf life of milk, freezing is an effective technique. Freezing milk can prevent food waste and allow for an extended storage period. However, it is crucial to transfer the milk to an airtight container and leave room for expansion as the liquid freezes. Thawed milk may have a different consistency, so it’s optimal for cooking and baking rather than consuming directly.
Understanding the nuances of milk expiration dates and proper storage practices is essential in determining whether milk is still good after its sell-by date.
Tips for proper milk storage and extending its shelf life:
- Store milk on the back shelf of the refrigerator to maintain consistent temperature.
- Check for spoilage signs: smell, color, consistency, and taste.
- Dispose of milk if spoilage is indicated.
- Freeze milk in an airtight container to prolong its storage period.
- Allow room for expansion when freezing.
- Thawed milk is best used for cooking and baking purposes.
By paying attention to the signs of spoilage and following recommended storage guidelines, consumers can minimize food waste and safely enjoy milk for as long as possible.
Frequently Asked Questions
Can you use milk 5 days past sell-by?
According to some evidence, milk that is 5 days past its sell-by date can still be safely consumed. This is especially true for pasteurized milk, which is known to have a shelf life of 2–5 days beyond the sell-by date. However, it is important to note that different methods of pasteurization can significantly extend the freshness of milk. Ultra-pasteurized milk, for instance, can remain fresh for around 30–90 days, making it a suitable option for those who might need to use milk beyond the usual expiration period.
Can you drink 1 week expired milk?
While it is generally considered safe to consume milk up to a week after its expiration date if it has been stored properly in the refrigerator, caution should still be exercised. The smell and appearance of the milk should be carefully inspected before deciding to drink it. Proper refrigeration can extend the drinkability of milk up to two weeks beyond the date label, but it is essential to trust your senses and discard it if any signs of spoilage are detected.
Can I drink expired milk if it doesn’t smell?
While your sense of smell and taste are indeed important in determining whether milk is safe to drink, it is crucial to remember that they are not foolproof. Even if expired milk doesn’t have a strange smell or taste, there is still a risk that harmful bacteria might be present. The expiration date is there for a reason, as it indicates the time by which the milk should be consumed for guaranteed safety. Consuming expired milk, regardless of its smell or taste, may lead to adverse health effects, so it is best to err on the side of caution and avoid drinking it.
How do you know if milk has gone bad?
One can easily determine if milk has gone bad by observing its texture, color, and smell. Spoiled milk often becomes lumpy, thick, and may acquire a slightly yellow hue. In terms of odor, fresh milk has a minimal scent, while spoiled milk emits a distinct sour smell that is hard to miss. Thus, by examining its consistency, color, and scent, one can easily identify if milk has gone bad.
