A Jew is not allowed to sell food forbidden on the biblical level, even to non-Jews. These include neveilot and treifot (section 11 above) as well as non-kosher animals, fish, or sheratzim (section 7 above). Similarly, a Jew may not raise non-kosher animals to provide food for non-Jews. Nevertheless, if a Jew happens to come into possession of forbidden food (for example, one owned an animal which became a treifa, or one laid a trap for a kosher animal but caught a non-kosher one), one may sell it to a non-Jew.
