There was a pot of soup that a fly fell into it. The fly was not located and therefore the whole soup became prohibited. Even though the soup might have 60 parts against the fly, still since the fly is an entity in and of itself it is not nullified in the soup even if there would be a 1000 parts against it.
The soup by mistake was then divided entirely into 3 separate bowls. Could we then say in such a situation that the soup is now permitted to eat since if looking at these three separate bowls we could say that the fly is in one of the bowls, however that it becomes nullified in the other bowls (the majority - 1 in 2 - bittul b'rov)
My doubt in this is since the pot of soup became prohibited to begin with it would therefore remain prohibited even when divided out into 3 bowls. Or perhaps now it would become nullified.
What is the din and what is proof for this?
