Almost all power cords and extension cords in the US contain lead: the lead is added to the plastic part of the cord when the plastic is still "molten" and its purpose is to make the plastic less flammable.
Although I did not do a chemical assay on it or anything, I am pretty sure that the power cord Apple included with my 2011 Mac mini contains no lead. (The cord has a different, more rubbery feel to it that strongly suggests a completely different material, and I might have seen a claim to that effect somewhere on the web.)
