Research supporting formula be made with 70 degree water

[Hopingforastickyone]

Hi,

Am currently having an argument with my father in law who is a professor of medicine regarding how formula should be made up.

He thinks the 70 degree rule is the silliest thing he has ever heard and would never hold up in a lab environment. He thinks the recommendation must be more due to preventing scalding as 70 degrees will not kill off all serious germs.

Unless i show him serious evidence I have no way of winning this argument.

Can anyone help me or point me in the direction of some valid research?

Thank so much!

is this any use

this had the above link

70C is the minimum temperature recommended. Presumably he's happy to drink pasteurised milk which involves heating milk to 71.7C?! The aim isn't to sterilise the milk but to kill off the majority of harmful bacteria, particularly Enterobacter sakazakii which is sensitive to temperatures above 60C. Essentially by making up babymilk this way you are pasteurising it, which is a fairly well established way of making milk safe to drink

TBH though, I doubt you'll win the argument whatever evidence you show him, it's probably got more to do with the "we never did this and our children survived" train of thought commonly exhibited by grandparents IME!
