If consuming the bulb of a cultivated onion, what safety principle applies to the attached green parts?

Answer

The attached green parts are safe components of the same edible plant.

The underlying principle governing the edibility of cultivated onion greens, derived from standard food varieties like bulb onions or red onions, is straightforward: since the bulb itself is being consumed, the attached leafy green portions are considered safe components of that same edible plant. This safety assessment applies because these greens belong to the *Allium* family members cultivated specifically for human consumption. They are functionally the leafy aspect of the plant, similar to chives or leek tops, and do not introduce new toxicity hazards provided they originate from standard food crops and are handled correctly.
