Cancer warning labels on products: A cause for concern?

By Elizabeth Landau
CNN.com Health Writer/Producer

For several months I have enjoyed recording digital music files through my keyboard, thanks to a simple device that connects it to my laptop. But it wasn’t until recently that I discovered that the following label came with it:

WARNING: This product contains chemicals, including lead, known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling.

I freaked out. How could a set of cables attached to a small blue blinking cylinder cause cancer? The USB connector and keyboard inputs seemed harmless enough, and I hadn’t felt obvious symptoms while making music. Was I risking my life for the sake of my four-person fan base?

So I called the company, M-Audio. Apparently, manufacturers have to put this label on certain products to comply with Proposition 65, a California law that requires a warning on anything containing lead or other hazardous substances found to cause cancer, birth defects, or other reproductive harm.

Under this law, whose full title is The Safe Drinking Water and Toxic Enforcement Act of 1986, warnings must be placed on products with a chemicals present in amounts larger than what the California government has decided is a “safe harbor number.”

These requirements are pretty strict. For example, for a cancer-causing chemical, according to the state’s Office of Environmental Health Hazard Assessment, “a person exposed to the chemical at the ‘no significant risk level’ for 70 years would not have more than a ‘one in 100,000’ chance of developing cancer as a result of that exposure.” So, if there would be more than one excess case of cancer out of 100,000 people over a period of 70 years because of exposure to that amount of the substance, slap on that label.

It’s not just computing equipment. Amazon.com outlines for its customers required warnings for California consumers placed on tools, lead crystal glasses, ceramic tableware, jewelry, Tiffany style lamps, electrical cords, beauty products, and even motor vehicles.

The consequences for violating Proposition 65 can be pretty fierce. One Los Angeles company had to pay a $10 million fine for failing to label lead-tainted lunch boxes (they sold 100,000 of them to the state health department), the Los Angeles Times reported earlier this year.

Still, does that mean I have to wash my hands every time I touch the cord? Mark Williams, spokesperson for M-Audio, says, “No! My gosh, no!”

In general, he says, electronics products carry this label because of the materials used in circuit boards, such as lead, for example. It’s not like there’s pesticide sprayed on the surface, he says.

In fact, according to the company’s official statement on the issue, a device with a lead warning might not have any lead at all:

Even in situations where an electronics device is completely free of lead, there is always a chance that standard third-party-manufactured accessories packaged with the device (such as a power cable, USB cable, or power supply) may contain trace amounts of lead. Out of professional diligence and a commitment to fully comply with the law, M-Audio properly marks all applicable products with a Prop 65 lead warning.

Maybe people are used to seeing these labels by now. Williams said mine was the first call he’s received on the issue in his five months in media relations at the company.

So, now I will make my techno versions of acoustic indie songs in relative peace.

    Back in the day, pencils had lead in them, I know I had them in my mouth, chewing away while in class or doing homework. I was actually stabbed with one when a classmate was handing one to me, I still have the mark on my palm if I look really hard for it, that was over 30 yrs ago and I'm still alive and kicking.

      Pencil "lead" is made with graphite and has been made with graphite since the 1500s or so. (Never lead. That was a misnomer.)

      Lead pencils contain graphite (a form of carbon), not lead. In fact, contrary to what many people believe, lead pencils never were made with lead. The ancient Romans used a writing device called a stylus. This was similar to the modern stylus used with smartphones and tablets, except it was bigger and made from lead.Nov 30, 2014

    The following text, as borrowed from Wikipedia, points out that the "lead" in pencils has been - for many a century now - made of graphite, etc., but not the (highly toxic) element Lead which was used by scribes in ancient Rome. I'm assuming you weren't chewing on pencils in school THAT long ago...

    "A pencil is a writing or drawing instrument consisting of a thin stick of pigment (usually graphite, but can also be coloured pigment or charcoal) and clay, usually encased in a thin wood cylinder..."

    ".. The archetypal pencil may have been the stylus, which was a thin metal stick, often made from lead and used for scratching on papyrus, a form of early paper. They were used extensively by the ancient Egyptians and Romans. The word pencil comes from the Latin word pencillus which means 'little tail'... "

    My main problem with all of these laws that go too far, including those that force you to be safe with your own life (seat belts) is the following.

    Are we trying to make people live forever? We do not have the room or resource for humans that live until 150 years old. Death is required. As horrible as that sounds, people need to die sooner or later.

    Frankly, a large portion of the population does nothing to add to the overall good. I'm talking about the increase in criminals and stupid kids that will never go anywhere. A bigger population just makes it worse by having less to go around, hindering the production of better people.

    I know this all sounds bad, even fascist in a way but its a fact that needs to be considered.

    Let people live they way they want and take the risks they want as long it doesn't pass on that risk to someone else. If they die....then so be it. I'd rather live to the fullest for a short period than lead a long dull existence. Live and stop worrying about death! There's nothing you can do to stop it.

      Wikipedia is not necessarily inaccurate or non-reputable; there's just a chance that the information may be bad if the author or an editor writes something without sourcing. However, if you think the information you're reading on Wikipedia is bogus, check to see if the writing is sourced. There will be a source number in line with the verbiage and a corresponding source at the bottom of the page for either a link or a reference to the paper source.

      This whole concept being passed around, especially by schools, of Wikipedia being labeled as a bad resource is nonsense. Now, that doesn't mean I would go write a paper and source Wikipedia, but I would be willing to go to Wikipedia to find sources.

      Enough said. Don't dog Wikipedia anymore. It's a fantastic product. You just need to know how to use it properly.

    Personally, I won't buy any product with this warning label. The onus should be on the manufacturer to use alternative and safer materials... why should I spend money on something that's going to give me and my family cancer. 1 in 100,000 (even after 70 years) is far too much. This junk needs to get off the market. Wake up, people.

      Does this stuff cause cancer in 1 in 100,000 people? I think the probability itself presents such a dramatic differential it would require an instrumentation of measurement not yet, or maybe ever, available to the upright bipedal humanoid. It seems like they could also say 1 in 100,000 people who's favorite color is blue get cancer, which may be true, and so on. At any rate, I'd like to know what scientific backing is available, if any, before I try to return that awesome knife I just bought. Let me know.

      I do, however, see where this could set a horrible precedent. WARNING labels are placed on everything; we buy them. Then there becomes no way to distinguish the highly toxic one from the not so toxic ones. Very bad business in my opinion if this is the case, and usually is. Look at our water supply.

      Joe- I see your point but almost everything we buy has that cancer warning label. My Faberware electric coffee pot and every other thing, including some pocket knives and food products have chemicals that may have traces of chemical causing cancer. California Proposition 65 requires that warning labels be placed on products containing chemicals causing health concerns in California so I think we should use these products in every other state except California or the politicians of every other state feel our health concern in not important enough to require that warning label to be required in their state.

    Death by music player? I think not.
    I think this law is just a LITTLE bit harsh.

    "...one in 100,000’ chance of developing cancer as a result of that exposure.”

    Yeah, let us attempt to save that 100, 101st person from dying of cancer from a MIDI used for 70 years straight even though it was probably obsolete by the fifth year they had it, and that the other 100,000 people will be saved, even though half of the other 100, 000 people will probably have cancer in some form anyway. Give me a break. But I do admit, as a rabid nature lover, I do give them props for ,erm, exuberance?

    My only fear with this is the meaning of the label is diminished. How does a person know how much lead or other dangerous chemical is in an object? I would imagine some products bearing that label may actually be dangerous to handle more than necessary, while evidently there is no danger at all to handle other products.

    It's amazing how there's no one leading one big effort to twarf the cancer epidemic. People die of cancer by the hundreds of thousands and no one knows why. They just keep going to work, hoping to be avoided. First there was the Dodo bird, then there was the chemical soup happy Dodo humans. We're killing the environment in which we live in and we're killing others and ourselves. Some Godly image. Looks like we are doing the same thing as a cancer does. -Frank was here.

    I understand the need for the warning labels on products, but there has to be a better measuring stick than the "more than one excess case of cancer out of 100,000 people over a period of 70 years". That is beyond extreme and just plain silly. Given what has been described in the article, I'm surprised we don't see that sticker on EVERY single item sold.

    California had a good intent in writing that law, but they went beyond sane. Overkill like this will cause those warning stickers to be useless as no one will bother to read/care about them since they will be ubiquitous.

    Just to clear up a point on some of the earlier posts - the lead in pencils was in the yellow paint on the outside, not in the graphite.

    Lead in anything is a bad thing. My family was poisoned by lead in our drinking water. It came from plumbing materials used to deliver the drinking water. It was a nightmare trying to identify what was causing our symptoms. The most vulinerable population are children who have developing brains and the fetus who can't expel the lead once exposed.

    I agree with John on this one. It is becoming more difficult to say what is really dangerous and what is not. Despite that, I appreciate labels of the sort that are definitely more honest than say- the mobile phone retailers who are quick to declare that mobile phone or wifi radiation is completely safe.

    But the article brought out the main drawback – out of fear of litigation, every company will put the sticker on every item, regardless of whether it contains lead or not, simply to cover their bases. We're reaching a point where every item on the market will have a generic, overly broad warning that it might in some way cause harm.

    Anyone using a computer right now has toxic heavy metals right next to them. To say "I refuse to buy these items for my health" might as well throw their computer, car, TV, cell phone, etc out right now. This is nothing new in our lives.

    You are right you shouldn't buy products with this warning label...but the warning label was in manual which was sealed in a plastic bag inside the box! Maybe if they put it on the outside like a pack of cigarettes but when they put in the back of the manual right after the Japanese section how am I suppose to see it before I buy it? Am I really going to go through the trouble of returning this product now? What a pointless thing! Now I don't like the idea of using this keyboard and my desire to study is really diminished.

    You interviewed ONE individual for your article, who happened to be the company spokesperson selling the item with the proposition 65 label.

    Is it any surprise that he would say that there is no cause for alarm?

    Poor journalism aside, it is irresponsible to the public for you to post biased opinions as fact.

    When I was 9 years old 1952, I found a piece of lead. The dimensions of the lead were about 4 inches long, 1 1/2 inches wide and 1/2 inch thick. I polished it with my hands daily, it was so smooth I even rubbed it on my face. This went on for about 3 months, until I lost the piece of lead. Knock on wood! I am now 67 years old, no signs of cancer yet. I have 4 healthy children ranging from ages of 37 to 47. I have 8 wonderful Grandchildren 5 to 20 years, all healthy. I thank God above for all.

    I find it ironic that California has cancer causing labels on all these innocent products, yet there are no warning labels on foods that are doused with cancer causing pesticides and herbicides( or preservatives for that matter). Aspartame itself causes poisoning resulting in MS symptoms. Now that's a label worth putting on.
