Toshiba AC adapter causes birth defects?

I needed a new AC adaptor for my Toshiba M4 and it arrived today.  For a simple AC adapter (Toshiba Part Number PA3283U-3ACA), it came in a huge box. 

Then when opening the box, the first sheet on top was:

In case the text is hard to read off of my Smartphone camera:

"WARNING: Handling the cord on this product will expose you to lead, a chemical known to the State of California to cause birth defects or other reproductive harm.  Wash hands after handling. "

WTF?  I realize California has some regulations on the books that require everything that may in the slightest way cause you harm be labeled, but since when did an electrical adapter cord contain lead?  The cord seems to be just plain ol electrical cord, covered in an insulator.  I don't get it. 

FWIW, there are two cords - the one that plugs into the wall has the following markings: "(PS)E JET HRS ICI VCTFK 2X0.75mm2 =F= 2006 CMC N.M  (UL) W69167-2 TYPE NISPT-2 2X18AWG VW-1 HI-RISE CSA LL973391 TYPE SPT-2 2x18AWG FT2"

The side that plugs into the tablet says "EVERTOP (S)E117873 <some weird symbol> AWM STYLE IS71 16AWG VW-1 80º 30V  CSA LL82009 AWM II A 80º 30V  FTI =F= JACKET LM"

I know there is probably some way to look up these codes, I just don't have the patience.  I always thought lead was a conductor and would have no place on the outside of a cable.  I'll have to keep this thing away from my wife since our second child is due in a few weeks.
