Breast milk is known to be the best source of nutrition for infants, providing them with all the necessary nutrients and antibodies to support their growth and development. However, it’s important to store and handle breast milk properly to ensure its safety and quality.
One of the common questions among new mothers is how long breast milk can stay fresh if it is not refrigerated. The answer to this question depends on various factors, such as the temperature of the environment and the cleanliness of the containers used for storage.
In general, freshly expressed breast milk can be safely stored at room temperature for a short period of time. According to the American Academy of Pediatrics, breast milk can stay good for up to six to eight hours at room temperature (around 25°C or 77°F). However, it’s important to note that this time frame may vary depending on the surrounding conditions.
If the ambient temperature is higher, it’s recommended to store the breast milk in a cooler or insulated bag to maintain its freshness for a longer period. On the other hand, if the room temperature is lower, the breast milk may stay fresh for a slightly longer time.
Storage Recommendations for Breast Milk
Proper storage of breast milk is essential to ensure its safety and quality for your baby. Here are some recommendations on how to store breast milk:
Refrigeration
For short-term storage, storing breast milk in the refrigerator is recommended. Place the breast milk in clean, capped glass or BPA-free plastic containers. Make sure to label each container with the date and time of collection. Breast milk can be stored in the refrigerator for up to 4 days at a temperature of 0-4°C (32-39°F).
Freezing
To store breast milk for a longer period, freezing is the best option. Use breast milk storage bags or clean, capped glass or BPA-free plastic containers that are specifically designed for freezing breast milk. Label each container with the date and time of collection. Breast milk can be stored in the freezer for up to 6 months at a temperature of -18°C (0°F) or lower.
Here are some tips to consider when freezing breast milk:
- Always use the first-in, first-out rule. Use the oldest milk first before using the more recently stored milk.
