Olga posted these links on the liver and bacon post out of personal experience but as they won't get seen there, here they are again.
Vit A toxicity 1
Vit A toxicity 2
Vit A toxicity 3
To reiterate, you have to be very, very, very unlucky to become ill from eating reasonable amounts of liver, but it does appear to be possible... For the rest of the world, outside of this small number people with specific vitamin A intolerance, enjoy liver. Bacon and onions are a great accompaniment!
Just for everyone's information.
