Can I feed frozen pig liver to a Caucasian?

A Caucasian can eat a little frozen pig liver, but thaw and steam or boil it first to avoid bacteria and parasites. When cooking, add no seasoning except a few grains of salt, never much, to avoid metabolic burden.

Do not feed only liver; mix chicken, beef, duck, and fruits/vegetables for balanced nutrition. Never feed liver long term, because its high vitamin A can cause vitamin A toxicity.
