Did Peter's Vision of the Sheet Mean People & Food?

[sari83]

I think that Peter's vision is referring to a spiritual cleansing, in regards to the gentiles. I do not believe the genetic structure of unclean animals changed to make them clean. Scientific research has shown that the animals that the scriptures deem to be unclean in fact contain parasites & disease, partially due to genetic predisposition.

If all animals have been cleansed for food purposes, what do these verses mean?

Isa 65:4
Which remain among the graves, and lodge in the monuments, which eat swine's flesh, and broth of abominable things is in their vessels;
(KJV)

Isa 66:17
They that sanctify themselves, and purify themselves in the gardens behind one tree in the midst, eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith the LORD.
(KJV)
