Today, the new Kashrus symbol of the famed Landau Hashgacha has been updated. Since the passing of Rabbi Moshe Yehuda Leib Landau, the symbol has been redone to include the names of his son and successor, Rabbi Chaim Yitzchok Isaac Landau, together with his partner, Rabbi Shevach Tzvi Rosenblatt. The updated logo is gradually replacing the previous one.
