That doesn't necessarily mean she recognizes you... that just means you don't smell like her food. Proof of that, for me, came when it took me 6 months to switch my rescued burm over from live rats to rabbits. She didn't "recognize" it as a rabbit...just didn't recognize it as something edible. Heck even right now I'm trying to switch 2 new balls over from live to frozen and they won't take it because they don't recognize the F/T as food.
If they really recognized you, you could rub a rat all over your hand and stick it in the tank without being bitten.
