322. People Whose Kashrus Standards are Unknown

46:21 If we don’t know what degree of kashrus a person might observe, we may not purchase from him wine or other foods that might be non-kosher. However, if one is a guest at this person’s home, one may eat unless he has reason to suspect the food might not be kosher. 46:22 One should not leave a cooking utensil in non-Jew’s home because he might use it with non-kosher food. If one gave a non-Jewish craftsman such a utensil to repair, if there is reason to suspect that he might use it, an authority must be consulted.
