Quality of human milk expressed in a human milk bank and at home

J Pediatr (Rio J). 2018 Jul-Aug;94(4):399-403. doi: 10.1016/j.jped.2017.07.004. Epub 2017 Aug 30.


Objective: To evaluate the quality of the human milk expressed at home and at a human milk bank.

Methods: This a retrospective, analytical, and observational study, performed by assessing titratable acidity records and the microbiological culture of 100 human milk samples expressed at home and at a human milk bank, in 2014. For the statistical analysis, generalized estimating equations (GEE) and the chi-squared test were used.

Results: When comparing the two sample groups, no significant difference was found, with 98% and 94% of the samples being approved among those collected at the milk bank and at home, respectively. No main interaction effect between local and titratable acidity records (p=0.285) was observed, and there was no statistically significant difference between the expected and observed values for the association between the collection place and the microbiological culture results (p=0.307).

Conclusions: The quality of human milk expressed at home and at the milk bank are in agreement with the recommended standards, confirming that the expression of human milk at home is as safe as expression at the human milk bank, provided that the established hygiene, conservation, storage, and transport standards are followed.
