10 It is forbidden to buy asafoetida from non-Jews if it is cut with their knives which have come into contact with non-kosher food, and so too with mixtures of fish, because small unkosher fish gets into the mixers and it is impossible to separate them, and they sometimes place wine to soak in the mixture. And this is forbidden to eat, but to benefit from it is permitted. And if it is known that they put wine in all of these, then they are forbidden even to benefit from. Rema: And you can sell them all, except if it has non-Jewish wine in it. And if it is known that a non-Jew will later be in a city where they do not mix wine, even though that other non-Jews are accustomed to do so, this is permitted to buy from them, as long as you don't know for certainty that they have mixed wine in, because we rely on this lenience that perhaps they have not mixed anything in. And so too for anything like this that is forbidden rabbinically. And if it is known with certainty that some non Jews mix wine in, and some do not mix wine in, then we go according to the majority, as it is unusually for a person to deviate from the norm. But it is forbidden to buy from them when they are at home, because one half is just like the other half in this regard.
