If you are that paranoid, you should not even own a computer or printer!

I rarely play with anything higher than a few MHz.
 
The "pill" molded transistors in early TV tuners weren't so robust - they
weren't exactly molded as such, they were 2 plastic shells glued together.

They pack *EVERYTHING* in anti static bags - there was a time anti static

All semiconductors need special handling. Usually I just wet my hands
and ground myself. That is plenty. Wet hands cant cause static
electricity. No other passive components need that (as far as I know).
Tubes are safe too.
