How about Trash's death in "Return of the Living Dead"? The scene cut away before we got to see her being eaten, and given the intelligence level of the zombies; you can definitely get creative in where she's bitten, and still pretend it's cannon.

Other ideas would be Clair Redfield having a run in with a Licker.

Or Mary Jane getting raped and devoured by either Carnage or a zombified Peter Parker.

Lots of emphasis on red. I love guro involving red heads. The curtains match the carpets and their insides do too!
