Kefir Kashrut
Question
Hello Rabbi,
What is your opinion regarding the kashrut of homemade kefir that was taken from a secular Jew? There is a discussion laying out the sides of the doubt at this link; there it seems they are lenient, but it looks like a non-simple leniency, and I wanted to check what your opinion is.
Best regards,
Answer
I see there that the issue is complicated, and unfortunately I do not have time right now to get into it.
Stay far away, my brother, stay far away. Eat only things that are definitely safe; don’t get involved with it.
