I read a while ago about leek that was stolen while it was still toxic from the pesticides. Apparently the leeks needed some more weeks for the toxins to flush

  For leeks to have a white portion of the stem (usually the part that is eaten), you have to bury part of it underground or it turns green. Presumably they use something like a soil fumigant to prevent spoilage of this underground part. Pretty nasty stuff if it actually renders the plant toxic for 6 weeks.
