Breast milk transport steps can differ between home, ward and milk-bank settings. Check current health-authority and institutional guidance together with instructions for the specific container instead of using a general online time limit.
Keep identity and status with every container. Keep the identity details required by procedure, expression date and time, and milk status legible on the container. At handoff, compare label, record and container integrity; transfer or pooling steps must come from approved instructions.
For storage, thawing and feeding decisions, follow the health service's current written procedure. A general transport article cannot determine whether milk is suitable for an infant.
