factory line residue

Question

What would be the maximum proportion of issur that could conceivably be found in any given food item as a result of factory line residue? Can you please address if there is any inyan to avoid such residue altogether?

Answer

Answered by Chaim Yisrael Abadi

it would be a minute amount, which would not be a problem. There is no inyan to avoid this at all, as there is no inyan to avoid batel b'shishim. CYA
