A general but off-topic question was posed related to this thought. See here: What is the significance of Acts 10:13, 11:7 "make sacrificial slaughter"
Acts 10:10-16 describes Peter's vision of animals of all sorts being placed before him with the command to kill and eat. Peter's statement in verse 14 seems to imply that his concern was the unclean status of the animals in front of him. He does not state anything about blood.
That being said, is there any implication of blood consumption in the wording of verse 13?
καὶ ἐγένετο φωνὴ πρὸς αὐτόν ἀναστάς Πέτρε θῦσον καὶ φάγε
