a small deposit of blood (very little) at the bottom of chilled ebm bottle. is it safe to consume?

Personally, I wouldn't do it but like the mommy above said, if you are okay with it, then go ahead. Here's an article with more information :) http://www.livestrong.com/article/549279-if-i-pump-blood-gets-in-the-bottle-is-it-still-ok-to-give-the-baby/

it's ok! it depends on how comfortable you are with it, i've seen mums feed their babies with bottles with blood that has tainted the milk pink. if you're not comfortable, then dont do it.
