This sounded like an urban legend to me, so I looked into it and learned that the lab that tested L'il Critters vitamins found trace amounts of lead in every single brand of vitamin that they tested, and in every case, the lead levels were all far less the amount considered unsafe. And in fact, the concenration wasn't any higher than that found in fruits and vegetables (yes, even organic produce).
Essentially the explanation is that lead is in our air and water, and can't be entirely eliminated (and this isn't necessarily all due to "contamination." Lead isn't only a contaminant, it's also a naturally occuring element. You can't get it out of everything, even if you wanted to.
So the issue really isn't "is there lead" (because there is - everywhere), but "are the levels of lead, safe," and from everything I could find online, the answer appears to be yes.
