More on Prop 65

The law requires California to publish a list of chemicals known to cause cancer or reproductive toxicity, and for businesses with 10 or more employees to provide warnings when they knowingly and intentionally cause significant exposures to listed chemicals.

As per the Prop 65 regulations, if a product, including foods and supplements, sold in California contains one or more chemical that is listed on the Prop 65 list of chemicals(https://oehha.ca.gov/proposition-65/proposition-65-list) that are “known to the state of California to cause cancer or reproductive toxicity”, then businesses need to notify customers about their presence with a warning for the product which may be required if exposure to that chemical is above the Safe Harbor Level (if one has been established). Failure to comply with the regulations can result in your company being issued a “60-Day Notice” of non-compliance or “Notice of Violation” and your company can be taken to court if a settlement is not reached. Settlement fees can cost companies tens of thousands to as much as several hundred thousand dollars. Compliance with this regulation cannot be ignored.

Is your business exempted ?

  • Governmental agencies and public water utilities.
  • Businesses with 9 or fewer employees.
  • Exposures that pose no significant risk of cancer.
  • Exposures that will produce no observable reproductive effect at 1,000 times the level in question.
  • Exposures to listed chemicals that occur naturally in foods.
  • Discharges that do not result in a "significant amount" of the listed chemical entering any source of drinking water.
