[Avodah] Pesach - Lecithin does not render chocolate non-KLP for Ashkenasim

[Ben Waxman via Avodah]

1) Has anyone on this list EVER strained milk and found chameitz (or 
anything else)? Have you even spoken to someone who did?
2) The prohibition of being m'vateil an issur applies to the super 
corporations that run the milk industry?

whether that would apply to chocolate, which was once liquid but is now 
solid.
