What does green breastmilk mean?(TMI)

I’m not sure if I had the stomach bug or food poisoning from old food I accidentally consumed, but I was (TMI) throwing everything in my stomach up and diarrhea and so on to the point nothing was in my system at all and that night I had to pump and my husband fed the baby because I couldn’t. The next morning I checked the milk I pumped (which I only got one ounce of milk out :((. ) and it was a greenish color. I didn’t have any leafy greens or green or blue colored foods. Is that bad? What’s wrong with my milk and is it safe to feed baby like this?
