The stained amniotic fluid (called "meconium liquor" or "meconium-stained liquor") is recognized by medical staff as a possible sign of fetal distress. Some post-dates pregnancies (when they are more than 40 weeks pregnant) may also have meconium-stained liquor without fetal distress. M…

Etymology
The Latin term meconium derives from the Greek μηκώνιον, mēkōnion, a diminutive of μήκων, mēkōn, i.e. poppy, in reference either to its tar-like appearance that may resemble some raw opium preparations or to Aristotle's belief that it induces sleep in the fetus.
Other uses
• In biology, meconium describes the metabolic waste product from the pupal stage of an insect that is expelled through the anal opening of the adult upon eclosion from the pupa. Other insects, such as beetles and some Hymenoptera (Aculeata) expel the meconium at the end of the larval stage, before becoming a pupa.
