Question: where in the bible does it say not to eat raw meat?
Answer: No. It might not be wise, but it's not a sin. After the Flood, God gave meat to man to eat. In 1 Corinthians chapters 8, 9, and 10, Paul states that all things are lawful to eat; even meat offered to idols, if it is done with a clear conscience and doesn't cause another to sin.
