I pretty positive that the warning was not to eat the Sun cows of Apollo, and after i think a month of being stranded on an island inhabited by them, some men killed a few of them and ate them, and no amount of offerings or libations could have saved them.
Circe wasn't a goddess she was a sorceress who lived on the island Aeaea and turned any men who came to her island into pigs until Odysseus stopped her with the help of the god Hermes.
