ToxStrategies has California-based staff and decades of experience assisting clients, including their internal or external counsel, who may be subject to the requirements of Proposition 65 or involved in litigation. ToxStrategies is a leading firm providing Proposition 65 expertise, with toxicologists who understand the calculation of safe harbor levels, exposure experts with experience conducting human-use exposure simulations, and scientists who regularly assess chemical exposures via food.

California’s Proposition 65, officially known as the Safe Drinking Water and Toxics Enforcement Act of 1986, established two primary requirements:

  1. Prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water.
  2. Requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm.

The Office of Environmental Health Hazard Assessment (OEHHA) is charged with implementing the requirements of Proposition 65. While perhaps well intentioned, Proposition 65 has spawned a slew of unintended consequences and significant litigation, greatly affecting companies doing business in California

ToxStrategies has assisted clients in evaluating a variety of situations relevant to Proposition 65:

  • Air emissions
  • Environmental exposures
  • Food or food-contact products
  • Household consumer products
  • Industrial products
  • Medical devices
