You dont need to worry. Teflon is made entirely from fluorine and carbon. Fluorine is so electronegative that the bond with carbon is insanely strong and teflon is therefore intensly difficult to break down into anything that could do you harm. its just too stable, that cooker could never ever get to the temperature required to do you harm.
As for dangerous substances, im in a pharmaceuticals degree so im regularly exposed to various acids, drugs, carcinogenics etc. of course i wash my hands afterwards, but over the years ive even had small amounts of heroin get on me and if you set alight my labcoat it would probably burn blue or something. Ive also been in contact with various radioactive substances spanning the whole length of alpha to gamma radiation, as well as exposed to multiple types of microscopic organisms used in research.
