By following safe preparation and storage techniques, nursing mothers and caretakers of breastfed children can maintain a high quality of expressed breast milk and the health of the baby.
Refrigerated or frozen breast milk may be stored in
|Countertop, table||Room temperature (up to 77°F or 25°C)||4 hours||Containers should be covered and kept as cool as possible; covering the container with a cool towel may keep the milk cooler.|
|Insulated cooler bag||5-39°F or -15-4°C||24 hours||Keep ice packs in contact with milk containers at all times. Limit opening the cooler bag.|
|Refrigerator||40°F or 4°C||4 days||Store milk in the back of the main body of the refrigerator.|
|Freezer compartment of a refrigerator||5°F or -15°C||2 weeks||Store milk toward the back of the freezer where the temperature is the most constant. Milk stored for a longer duration in the freezer may cause lipids in the breast milk to degrade resulting in lower quality|
|Freezer compartment of a refrigerator with separate doors||0°F or -18°C||3-6 Months|
|Chest or upright deep freezer||-4°F or -20°C||6-12 months|
