3.4. Temperature considerations
Advice provided for human milk storage intended for donation is more prudent than that for milk intended for home use (PATH,). For milk collected for ones own infant,freshly expressed milk is safe at room temperature for 4–6 h and at 15?C for 24 h (Pittard et al.,). At 4?C,human milk can be safely stored for 4–8 days. Breakdown of fat occurs at storage temperatures above −70?C,and samples stored at −20?C exhibit a reduction in fat over time (Schlotterer & Perrin,). Milk that is intended for donation should be chilled immediately and frozen within 24 h of expressing with a new container used every 24 h to reduce the introduction of contaminants. Freezing for up to 9 months does not appreciably affect total protein,fat,lactoferrin,sIgA or osmolality but reduces pH,folate,vitamin C,and total bacteria count (Ahrabi et al.,; Bank et al.,). Whilst recommendations differ,in North America,milk is acceptable for donation for up to 3 months from expression if stored in a freezer that is part of a fridge‐freezer and for up to 6 months from expression if stored in a free standing −20?C freezer (HMBANA,).","department":"
