Can You Store Breast Milk in Regular Ziploc Bags?
Storing breast milk is a crucial aspect of breastfeeding, especially for mothers who need to express milk for later use. The question of whether regular Ziploc bags can be used for this purpose has garnered attention, and the answer is nuanced.
Yes, You Can Use Ziploc Bags, But With Caution
According to various sources, it is indeed possible to store breast milk in Ziploc bags, provided they are clean and food-safe. This option can be particularly useful in situations where specialized breast milk storage bags are unavailable. Ziploc bags can be used for both refrigeration and freezing of breast milk, making them a convenient alternative in a pinch.
However, there are important considerations to keep in mind. While Ziploc bags are generally thicker and BPA-free, they were not specifically designed for breast milk storage. This raises concerns about potential leaks and contamination. The risk of spills is higher with Ziploc bags compared to containers that are specifically made for breast milk, which are designed to be sterile and leak-proof.
The Risks of Using Ziploc Bags
Experts caution against using Ziploc bags as a primary storage method for breast milk. The main issues include:
1. Sterility: Ziploc bags are not sterile, which increases the risk of bacterial contamination. Breast milk is a delicate substance that can spoil if not stored properly.

2. Leakage: Many mothers have reported issues with Ziploc bags leaking, especially when thawing frozen milk. This can lead to waste and frustration.
3. Durability: While Ziploc bags are thicker than standard plastic bags, they are still more prone to punctures and tears compared to dedicated breast milk storage bags.
Best Practices for Storing Breast Milk
If you choose to use Ziploc bags for breast milk storage, here are some best practices to follow:
– Ensure Cleanliness: Always use clean, food-safe Ziploc bags. Wash your hands before handling the bags and the milk.
– Label and Date: Clearly label each bag with the date and time the milk was expressed. This helps in managing the freshness of the milk.
– Limit Storage Time: While breast milk can be stored in the freezer for up to six months, it’s advisable to use Ziploc bags for shorter periods to minimize the risk of spoilage.
– Consider Alternatives: Whenever possible, opt for breast milk storage bags that are specifically designed for this purpose. These bags are made to withstand freezing and are often pre-sterilized, reducing the risk of contamination.
In conclusion, while Ziploc bags can serve as a temporary solution for storing breast milk, they are not the ideal choice. For the best results and to ensure the safety of your milk, investing in dedicated breast milk storage bags is highly recommended.

Can bacteria grow in Ziploc bags?

“You can reuse Ziploc bags as long as they haven’t been used for raw meat or other TCS foods,” Hutchings said. “TCS (time/temperature control for safety) foods are more susceptible to bacterial growth than shelf-stable foods, so if you store a TCS food item in a Ziploc bag, there may be more germs inside the bag.”
