Fish
Question
When the man in the supermarket cuts the kosher fish, it's possible that there might be some oil left on his knife, even if he washed it off. Is this something to be concerned with, or is it batel be-shishim?
Answer
Answered by Aaron AbadiThe fish is raw & cold & will be washed when you get home. The problem will be when it is Sushi. Aaron Abadi
