Lead Paint Chips

My landlady told me the other day that my new apartment has lead paint in it, which has been covered over by non-lead paint. Not a huge concern of mine, considering it could have asbestos in it instead, or growing mold from within. However, she made it a point to state it as thus:
"The walls have lead paint on them. So don't chip off the paint and then eat it. I'm serious."

This makes me wonder if she's had problems with this sort of thing in the past.
