DARBY STAYS COMPLIANT WITH PROP 65
Proposition 65 (Prop 65)
Enacted by the State of California in 1986, as the Safe Drinking Water and Toxic Enforcement Act.
Voters passed the proposition in response to growing concern about chemicals entering the
environment and drinking water supplies.
Prop 65 requires companies to provide “clear and reasonable” warnings to consumers if their products
contain a chemical, or chemicals, determined by the State of California to cause cancer,
birth defects or other reproductive harm and/or reproductive toxicity. Many of these chemicals
may be naturally present in the environment, for example, trace amounts found in soil. Prop 65
is among the strictest reporting laws in the nation.
Over 900 chemicals are currently listed under Prop 65, and the presence of these low
chemical levels require warnings only. Prop 65 does not ban the sale or use of any
product for health or safety reasons.
The Prop 65 Warning
The State of California has identified the following warnings to be clear and reasonable for consumer product protection:
"WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm."
"WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov"
Products that Require the Prop 65 Warning
Consumer products distributed or sold in California to consumers are subject
to Prop 65 warning requirements. The law also covers warnings for environmental and workplace
exposures to listed chemicals. Prop 65 warnings are required for products containing amounts
of chemicals that exceed the State of California’s daily exposure
thresholds, based on average consumption.
Chemicals that are subject to Prop 65 Warning
Under Prop 65, the State of California is required to maintain a list of chemicals
that it identifies as carcinogens or reproductive toxicants. The current list
of over 900 chemicals is routinely updated as chemicals are added or deleted.
The current list can be found at https://oehha.ca.gov/proposition-65/proposition-65-list
If you have lived in the state of California, you know that these warnings are very common.
They are found nearly everywhere. They are a requirement for nearly any organization that wants
to do business in California, and Darby is no different. Because Darby seeks to
comply with the strictest regulations of quality, Darby has voluntarily chosen to
include Prop 65 warnings on products sold.
Many common ingredients and minerals, like calcium can contain levels of Prop 65-listed chemicals.
These may include lead and other heavy metals, which are widely distributed
through soil, the air, water, and in food.
Levels of Prop 65-listed Chemicals that Trigger a Warning Label
The State of California’s threshold limits are very strict. For carcinogens, anything
above the “No Significant Risk Level” requires a label. This is the level of exposure
that would result in one case of cancer in 100,000 individuals, who would be
hypothetically exposed to high doses of the chemical every day over their lifetime.

Darby is Compliant with Federal Safety Guidelines
Darby takes pride in being fully compliant with all federal guidelines for product safety,
including those guidelines established by the Food and Drug Administration (FDA). The warning
thresholds identified by Prop 65 are often drastically lower than any federal guideline.

While Darby supports Proposition 65, it is important to remember that this is a “right to know”
statute, and that the inclusion of a warning does not mean that a product is necessarily unsafe.
