From personal experience, I was a one-sided nurser and the milk was ALWAYS
bluish tint from the side with high production.  The other breast was hardly
ever nursed on, didn't have great production, and it's milk was ALWAYS
yellow.  After pumping I would pour the two collection bottles together....
aha.. the milk was green.

Once in a while the same subject being tossed around on Lactnet has also
been discussed on other lists.
I saw these replies on NICUNET (listserv for neonatologists and HCP's
working in NICUs)
a while ago and thought you might be interested in some of their replies:

1.  "The greenish tinted  milk that I have seen has generally been related
to something in mom's diet i.e. a lot of green vegetables or a dietary
supplement such as alfalfa.  This subject is addressed in Dr. Ruth
Lawrence's book  "Breastfeeding for the Medical Professional".  I just
looked up colors of milk in the index yesterday, as a matter of fact.  There
are many colors of breastmilk - pinkish  (if a capillary has burst, or if a
mom has bleeding cracked nipples there may be a tinge of blood), bluish
milk, rust-colored milk, orange, golden, etc.  With most of these
variations, the milk is fine - if the infant were nursing, no one would ever
know what color the milk had been anyway.  Hope this helps."

2.  "My one experience with green breast milk was that the breast milk
> culture was positive for Serratia.  The milk was only slightly green
> tinged and our mother also did not have any symptoms of being ill or
> having mastitis.  This milk was fed to a 32 week premie while the
> breast milk culture was pending.  At about the same time that we got
> the culture result back, the infant was also exhibiting some subtle
> signs of possible sepsis, i.e. increased apnea.  The infant was
> treated with antibiotics based on culture sensitivies and the maternal
> breast milk was discarded until repeat culture was negative two weeks
> later.  The infant responded well to the antibiotics and had no
> sequelae.  Mother received intensive education on the proper storage
> techniques for breast milk.  It turned out that in order to prevent
> dripping of breast milk and staining through her blouse, she had the
> same towel over her breasts for days without washing and without
> cleansing between breast pumping times."

3.   "We have had a similar situation with Green Breast Milk. The milk grew
Serratia . In another infant who developed Serratia Sepsis We cultured his
mother breast milk and it grew Serratia. The Milk was only slightly dark. We
teach mothers proper pumping procedures through our lactaion consultant."

Something to think about?    My own healthy full-term daughter never
exhibited any signs of illness, GI disturbance, etc. from my green milk.
