Which statement about the storage of breast milk needs to be revised?

The statement indicating that fresh breast milk can be stored in the refrigerator for up to 1 week needs to be revised because the accepted guideline suggests that fresh breast milk should actually be used within 3 to 5 days when stored in the refrigerator. While some sources may state a storage duration up to 7 days, the more conservative and commonly recommended timeframe is 3 to 5 days to ensure the milk maintains its quality and safety for the infant.

The other statements regarding breast milk are aligned with established guidelines: breast milk can indeed be frozen for up to 6 months to maintain its nutritional value, freshly pumped breast milk should ideally be used within 4 hours to minimize bacterial growth, and once breast milk has been thawed, it should not be re-frozen to preserve its quality and safety. Therefore, the storage duration in the refrigerator is the statement that requires revision to reflect the more accurate recommendations.
