Do your snakes remember you?

[mrmertz]

And the jacob organ helps recognize the difference between are sent and the sent of food, the question is not can the snake recognise the same sent over and over again, the problem lies in the snakes inability to remember that sent and connect it to a person.

Okay, then I misunderstood the OP. If he was asking can a snake scent an individuals discreet scent, then no - I don't believe they can.
