Donor milk (DM) is of increasing interest as primary nutritional source for preterm infants. Safe access requires special infrastructure, trained staff, sophisticated algorithms, and standard operating procedures as well as quality control measures.
DM has limitations like low protein content and unpredictable composition of the other macronutrients, despite fortification frequently not meeting recommendations – both of them compromising growth. The first paragraph is devoted to COVID-19 and how it impacts processes of DM banking. The following paragraphs review aspects of “pasteurization,” “safety audits/donor screening,” and “DM nutrient variability.”
In summary, (i) Holder pasteurization still is the most suitable procedure for milk banks, but high-pressure pasteurization or ultraviolet C irradiation conserve the unique properties of DM better and deserve more research to make it suitable for clinical routine. (ii) In regard to safety/screening, guidelines are valuable for safe DM bank operation, but they differ between legislations.
There is a surprisingly high rate of non-disclosed donor smoking (0.3%, p > 0.05) and of adulteration of delivered DM (up to 2%, p < 0.05) not detected by standard donor screening procedures. Frequencies differ between remunerated and non-remunerated programs.
(iii) Neonatal caregivers should be aware of unpredictable composition of DM. They should be trained on how these can be overcome to avoid negative impact on growth and long-term outcomes like (a) measuring and disclosing nutrient contents of delivered DM batches to customers, (b) implementing certain types of donor pooling to reduce the risk of macronutrient depleted DM, (c) additional supplementation using 0.3–0.5 g protein/100 mL seems to be reasonable, (d) adjusted fortification may help to improve growth, but is not efficient in all preterm infants, (e) target fortification seems to improve growth (and probably also neurodevelopmental index) compared to standard fortification, (f) more research and clinical studies are needed.
