443. Being Repaid with Non-Kosher Food

64:3 One may accept non-kosher foods as payment for a debt so long as he sells them immediately. This is because one may not retain such things in order to make money off of them. One may, however, hang onto them so that they not lose their original value.

64:4 One may engage in business involving something that is only forbidden by rabbinic enactment, such as non-Jewish cheese.
