California Proposition 65 FAQ

California's Proposition 65 entitles California consumers to special warnings for products that contain chemicals known to the state of California to cause cancer and birth defects or other reproductive harm if those products expose consumers to such chemicals above certain threshold levels. We care about our customers' safety and hope that the information below helps with your buying decisions.

We are providing the following warning for products linked to this page:
----
WARNING: This product can expose you to chemicals including lead which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov/food.

What is this warning?
These warnings are required by California labeling law Proposition 65 (or Prop 65 for short), which is meant to notify individuals in California of exposures to Prop 65-listed chemicals. Prop 65 does not ban the sale of any products containing these chemicals; it only requires warnings.

Does this law apply everywhere?

The “Prop 65” warnings are only required under California law. Prop 65 standards are among the most stringent standards in place anywhere and are often far more stringent than federal standards. Our products, for example, fall well below the lead limit set by the United States Pharmacopeia, as well as the limit the FDA has set for juice (50 ppb) and candy (100 ppb).

What kinds of substances require warnings?

Over 800 chemicals have been listed under California Prop 65. They include pesticides, heavy metals, and Vitamin A at certain levels. Certain listed chemicals, such as lead, are widely distributed through the environment in air, soil, water, and rocks. As a result, these types of chemicals are often found in commonly eaten foods and throughout the food supply even though these chemicals are not added to foods or nutritional supplements. Common foods that naturally contain lead include seafood, chocolate, cocoa powder, potatoes, wine, cheese, milk (and proteins from cheese and milk), cabbage, cereal, lettuce, avocado, and many more.

Should I be concerned?

You should always be aware and take heed of all product warnings, but also always do research of your own. For Prop 65 reproductive toxicants, the level for warnings is 1000 times lower than the lowest level at which animal studies reported no reproductive health effect. A Prop 65 warning does not automatically mean that the product is unsafe.

How are these warnings determined?

California has a formal process for adding chemicals to the Prop 65 list. Prop 65 allows chemicals to be listed in various ways, including through reports that are based on animal studies. In many instances, these animal studies involve extremely high dosages of chemicals.

What kinds of substances are we talking about?

Many dietary supplements contain substances that require a warning in California. One vitamin that requires a warning above a certain level is Vitamin A. Incidental contaminants such as lead and mercury also require warnings above a certain level even if they are not added intentionally to a product.

How do the California warnings compare to federal limits?

It should be noted that California product label warning requirements are not usually the same as federal safety requirements. This causes a mismatch between warnings on products sold in California and what is required elsewhere in the U.S.A. So this can explain why sometimes you may see a California Prop 65 warning on a product sold in California but no warning on the same product sold elsewhere. The products are not different; it’s just that Prop 65 warnings are required for sales to California consumers. Additionally, there are various substances that require a California Prop 65 warning at levels that are far more stringent than federal action limits. One example is lead. The Prop 65 standard for warnings for lead is 0.5 micrograms per day, which is far more stringent than United States Pharmacopeia and international standards for lead.

Why don’t all similar products carry the warning?

There could be a variety of reasons. The most common being, many companies are not aware that they are supposed to be showing it if they are selling their product in California. If a company has been involved in a Prop 65 lawsuit, and if that company reaches a settlement, that settlement may require Prop 65 warnings for products. Other companies that are not involved in the settlement, although they may nonetheless sell similar products, may not provide a warning on their product. Because of inconsistent Prop 65 enforcement, this sometimes explains why you will see certain products in the market with warnings, and virtually identical products without warnings. Other companies may elect not to provide warnings because, in their assessment, they conclude that they are not required to do so under Prop 65 standards. A lack of warnings for a product does not necessarily mean that the products is free of the same substances at similar levels.

I’m confused, now what?

Prop 65 warnings are seen throughout California in a wide range of settings -- in restaurants, grocery stores, hotels, schools, hospitals, and on a wide variety of consumer products. In addition, some internet and mail order retailers have chosen to provide Prop 65 warnings on their websites or in catalogs for all their products and for all consumers. If you want more information, the one thing to do is to ask the manufacturer to explain the warning. But please remember that just because another brand does not have the warning, this does not automatically mean that the other brand is free of the substance or has lower levels.
