Continuity mistake: In the first "Present day" scene, the Ravencroft wardens enter Shriek's cell to feed her. She is lying on one side in the establishing dolly, and she's just lying on her back in the next shot. (00:04:10)

Answer: It is deliberately never shown on screen, so unless it gets answered in a sequel the audience is left to speculate. Mulligan does come into direct contact with Carnage since Cletus is the person who kidnapped him. In addition, the fight between Venom and Carnage takes place all over the church with the pair constantly stabbing, slashing, and bludgeoning each other. A piece of either symbiote could be somewhere in that building. Again, though this is just speculation since it's never shown how Mulligan is infected.
