Stored Milk Information

Milk that has been in the freezer for six months or less can be donated once the donor screening process is finished. Milk donation can occur if:

  • Milk is stored in single-use, sterile breast milk pump bags or bottles
    • We do not accept milk stored in glass jars, ice cube/milk trays, zip bags or containers not intended for breast milk storage
  • Each bag or bottle is dated with the date the milk was pumped
    • Do not combine different pumping sessions from different dates
    • Do not mix temperatures when combining milk (only mix cooled milk with cooled milk)
  • Milk is frozen within 4 days (less than 24 hours preferred) of pumping
  • Milk is not scalded/heated before freezing or thawed and then re-frozen
  • It does not contain restricted medication or alcohol
  • Pump parts have been cleaned using hot, soapy water after each use
