It would have been on the surface of the onions. Most likely from using untreated water to clean them prior to shipping.

Actually green onions grow close to the ground and when watered with contaminated water, the water is taken up within the scaly bulb of the green onions.

Other onions aren't as susceptible since they usualy have a tougher skin.

Also I have read that a lot of green onions are imported since green onions have to be hand picked which is very expensive. Other onions can be mechanically harvested.
