Roman bread stamps?

[nancylebov]

This article about a beautifully preserved loaf of bread from Pompeii, mentions"a Roman bread stamp, which bakeries were required to use in order to mark the source of the loaves, and to prevent fraud", but I haven't been able to find out anything about the regulations or how bread stamps were supposed to keep the bread supply honest. Anybody know?

Bread stamps would make the bread loaves trackable -- if someone's bread made people ill, or contained plaster or wood dust instead of flour, the stamp would make it possible to find out who baked it, and have the Praetorian Guards go investigate.
