Teshuvot Maharam
A. In France such bread is not eaten by Jews; even the sale of such bread to a Gentile is prohibited, lest the latter resell it to a Jew. The reason for this is that a Jew is permitted to eat bread baked by Gentiles from flour belonging to Gentiles, but he is not permitted to eat bread baked by a Gentile from flour belonging to a Jew.

Teshuvot Maharam
A. This bread may not be eaten, lest perchance one eat it with milk. However, it may be sold to a Gentile, since in a Rabbinical prohibition we do not take into consideration the remote possibility that the Gentile will resell the bread to a Jew.
This Responsum is addressed to R. Tobiah.
