Cooking with and refreezing EBM...

[macdoodle]

Some quick advice before next ad break
I have a few oz left over EBM this has prev been frozen and defrosted and warmed up (in boiling water)and has now been stood at room temp for about 3 hrs
I also have some left over boiled potatoes - is it ok to use the EBM for a batch of mash/puree potatoes and then freeze it...??
Complicated I know - so can frozen EBm be defrosted/warmed up/cooked with and then refrozen???

No. Not if it was just warmed up (so not boiled) and then stood at room temp for 3 hours. That's plenty of time for bacteria to multiply.

If you cooked the milk after defrosting, so it came up to boiling point and was held at this temp for a while, and then quickly cooled it and froze it and then heated it up to over 75C after defrosting it would be ok. But not now.

I wouldn't

if you'd cooled it and stuck it back in the fridge after dd didn't drink it then I might, but the 3h at room temp makes me say no

use cows' milk in the spuds if she's >6m
