Expressed breast milk is a valuable resource for nursing mothers. Whether you’re returning to work or just want some extra flexibility, pumping and storing breast milk can be a real game-changer. But how long can expressed milk stay in the refrigerator before it goes bad?
When it comes to storing breast milk, it’s important to follow the guidelines to ensure the safety and quality of the milk. The general rule of thumb is that expressed milk can be stored in the refrigerator for up to four days. However, there are a few factors to consider that may affect this timeline.
The freshness of the milk plays a significant role in how long it can be stored. If the milk is freshly pumped and hasn’t been sitting out at room temperature for an extended period, it will last longer in the refrigerator. On the other hand, if the milk has been left out for more than an hour, it’s best to discard it instead of refrigerating.
Another factor to consider is the temperature of your refrigerator. It’s crucial to keep the refrigerator temperature at or below 4°C (39°F) to ensure the milk stays fresh for the recommended timeframe. If your refrigerator is warmer than this, the milk may spoil sooner, and it’s recommended to use it within two to three days.
Guidelines for storing expressed milk
Proper storage of expressed milk is essential to maintain its quality and ensure its safety for your baby. Follow these guidelines to safely store your expressed milk:
1. Clean and sterilize containers
Before expressing milk, make sure to clean and sterilize the containers you will be using for storage. Wash them with warm water and mild soap, then rinse thoroughly. You can also use a dishwasher to sterilize bottles and pump parts.
2. Label the containers
After cleaning and sterilizing the containers, label them with the date and time of expression. This will help you keep track of the freshness of the milk and ensure that you use the oldest milk first.
3. Use airtight containers
Store expressed milk in airtight containers to prevent contamination and maintain its freshness. You can use glass or BPA-free plastic containers specifically designed for breast milk storage. Avoid using regular plastic bags as they may leak or break.
4. Store in the refrigerator
The refrigerator is the best place to store expressed milk for short-term use. Place the containers at the back of the refrigerator where the temperature is colder and more consistent.
Here are the general guidelines for storing expressed milk in the refrigerator:
- Freshly expressed milk: Up to 4 hours
- Room temperature milk: Up to 6-8 hours
- Thawed milk: Up to 24 hours
Remember to always check the milk for any changes in smell, color, or texture before feeding it to your baby. If in doubt, discard the milk.
5. Consider freezing for long-term storage
If you don’t plan on using the expressed milk within the recommended time frame, consider freezing it for long-term storage. Freezing slows down the growth of bacteria and helps preserve the nutrients in the milk.
Here are the general guidelines for freezing expressed milk:
- In a standard freezer: Up to 6 months
- In a deep freezer: Up to 12 months
Remember to use airtight containers or breast milk storage bags specifically designed for freezing. Label the containers with the date of expression and use the oldest milk first.
When thawing frozen milk, do it gradually in the refrigerator or under warm running water. Avoid using the microwave as it can create hot spots and destroy some of the beneficial properties of the milk.
By following these guidelines, you can safely store and use your expressed milk, providing your baby with the essential nutrients and benefits of breastfeeding.
How to store expressed milk safely
Proper storage of expressed breast milk is essential to ensure its safety and maintain its nutritional value. Here are some guidelines to follow:
1. Wash your hands
Before expressing milk or handling any storage containers, it is important to thoroughly wash your hands with soap and water to reduce the risk of contamination.
2. Use clean containers
Choose BPA-free containers that are specifically designed for storing breast milk. Clean these containers with hot, soapy water or wash them in the dishwasher before use.
3. Label the containers
Always label the containers with the date and time of expression. This is important to ensure that the oldest milk is used first.
4. Store milk immediately
After expressing breast milk, store it in the refrigerator as soon as possible. The sooner you refrigerate it, the longer it will retain its quality.
5. Store in small quantities
It is recommended to store breast milk in small quantities, such as 2 to 4 ounces, to reduce waste. This also allows for faster thawing when needed.
6. Avoid overfilling containers
Avoid filling storage containers to the brim. Leave some space at the top as breast milk expands when frozen.
7. Use refrigerator thermometers
Keep a refrigerator thermometer in the fridge to ensure that it is set to the optimal temperature for storing breast milk, which is between 32°F and 39°F (0°C and 4°C).
8. Follow the “rule of four”
Stored breast milk can be safely given to a baby as long as it has been stored for no more than four hours at room temperature, four days in the refrigerator, or up to six months in a freezer compartment within a refrigerator.
9. Thaw milk carefully
If frozen, thaw breast milk by placing the container in the refrigerator overnight or by warming it in a bowl of warm water. Avoid using a microwave to thaw or warm breast milk as this can cause hot spots that may scald the baby.
10. Shake gently
Before feeding breast milk to a baby, gently swirl the container to mix the cream that may have separated. Avoid vigorous shaking, as this can damage the proteins and nutrients in breast milk.
Following these guidelines will help ensure that your expressed breast milk remains safe and nutritious for your baby.
Factors influencing the storage time of expressed milk
1. Temperature: The temperature at which expressed milk is stored plays a crucial role in determining its shelf life. Breast milk can be stored in the refrigerator at a temperature of 4°C (39°F) or lower. This low temperature helps inhibit the growth of bacteria and other microorganisms, extending the storage time.
2. Cleanliness: Ensuring proper cleanliness during the expression, handling, and storage of breast milk is essential for maintaining its quality and safety. Make sure to wash your hands before expressing milk and use clean containers to store it. This helps prevent the introduction of bacteria and other contaminants that can spoil the milk.
3. Air exposure: Exposure to air can lead to the oxidation of expressed milk, reducing its nutritional value. It is important to minimize air exposure when storing breast milk. Use containers with tight-fitting lids or covers and avoid shaking or stirring the milk excessively.
4. Storage containers: The type of storage containers used for expressing and storing milk can also affect its shelf life. It is recommended to use BPA-free plastic bottles or storage bags specifically designed for breast milk storage. These containers are sterilized, safe, and help maintain the quality of the milk for a longer period.
5. Freshness: The freshness of expressed milk at the time of storage also influences its storage time. Refrigerating milk soon after expression helps preserve its freshness and extends its shelf life. Avoid storing milk that has been left at room temperature for more than 2 hours, as it may become unsafe for consumption.
6. Guidelines: It is important to follow the guidelines provided by healthcare professionals or breastfeeding consultants for proper milk storage and handling. These guidelines take into account factors such as storage time, maximum duration, and temperature limits to ensure the milk remains safe and suitable for feeding your baby.
7. Quality of breast milk: Lastly, the quality of the breast milk itself can affect its storage time. Milk from mothers who have a healthy diet, adequate hydration, and proper breastfeeding techniques tends to have a longer shelf life. Taking care of your health and following a balanced diet can positively influence the storage time of expressed milk.
In conclusion, several factors influence the storage time of expressed milk, including temperature, cleanliness, air exposure, storage containers, freshness, guidelines, and the quality of breast milk. By considering these factors and adopting proper milk storage practices, you can ensure the longevity and safety of your expressed milk.
