Milky Iceberg...ever happen to you?

[critter101]

Last night, I cut a head of iceberg lettuce in half, and it started oozing a milky liquid. It was coming from between the leaves. Needless to say, we didn't use it. But, I've never seen this before, and I have been cooking for a looooong time. Has it ever happened to you? Any idea what caused it?

Yes and with romaine. It is fine to eat.

From Wikipedia if you trust that..."The thick ribs, especially on the older outer leaves, should have a milky fluid which gives the romaine the typically fine-bitter herb taste."

No and I hope never to have it happen.
