California Proposition 65: What is it and what is its impact?

Proposition 65, officially known as the Safe Drinking Water and Toxic Substances Enforcement Act of 1986, is a state regulation in California that has had a significant impact on industry, commerce, and consumers since its passage.


This law was designed to protect California residents from exposure to chemicals that can cause cancer, birth defects, or other reproductive harm.


In this article, we will explore in depth the background, objectives, operation, and implications of Proposition 65, highlighting its relevance to both manufacturers and consumers.

Main objectives of Proposition 65

  1. Inform the public about the presence of hazardous chemicals in their environment, food or consumer products, so that they can make informed decisions.

  2. Prevent contamination of drinking water by regulating substances that may be hazardous to human health.

  3. Encourage manufacturers and distributors to reduce exposure to toxic substances by encouraging product reformulation and the elimination of harmful chemicals.


Proposition 65 has become a key public health tool in California, requiring companies to warn consumers about potential risks associated with certain products and forcing industry to seek safer alternatives.


Operating Mechanisms

Proposition 65 operates through a system of warnings and regulations that

companies must follow. Its central axis is a list of chemicals that the state of California considers carcinogenic or toxic to reproduction.


This list is maintained and regularly updated by the Office of Environmental Health Hazard Assessment (OEHHA). As of October 2024, the list contains over 900 chemicals.


Mandatory warnings

One of the key requirements of Proposition 65 is that companies must provide clear and reasonable warnings if their products contain any chemicals at levels that may pose a health risk.


These warnings are often found on product labels, in stores, or on websites, and are easily recognized by the phrase:

Mandatory warnings

"WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm."


"Warning: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm."


Exceptions and security levels

Although the law is strict about warnings, not all exposures require product labeling. OEHHA has established safe exposure levels, which indicate the minimum amounts of certain substances that do not pose a significant risk to health. If exposure to a substance is below these levels, no warning is required.


Impact on Industry and Consumers


Implications for businesses

Proposition 65 has had a major impact on manufacturers, distributors, and retailers selling products in California. To comply with the law, many companies have chosen to reformulate their products to reduce or eliminate hazardous chemicals from their production lines, thereby avoiding the need to post warnings.


In some cases, non-compliance can result in costly litigation, as Proposition 65 allows any citizen, organization, or environmental group to file lawsuits against companies that fail to comply with regulations. This has led to a high volume of litigation and financial penalties in cases of non-compliance, increasing pressure on companies to adjust their business practices.


Impact on consumers

For consumers, Prop 65 provides critical information about the risks associated with certain products. Warnings allow people to make informed decisions about what they buy, whether they choose to avoid products with warnings or simply become familiar with the potential risks. However, there has also been some criticism and confusion due to the number of warnings visible on common products, raising concerns about whether the warnings are being interpreted correctly or whether they cause unnecessary alarm.


Controversies and Criticisms

Despite its goal of protecting public health, Prop 65 is not without its critics. One of the most common complaints is that the law can lead to “over-warning,” meaning that many companies, to avoid legal risks, place warnings even on products with minimal exposures that do not pose a significant risk.


This can dilute the impact of warnings and create confusion among consumers, who may not be able to distinguish between products that pose a real risk and those that are labeled as a precaution.

.

The law has also been criticized for giving rise to abusive lawsuits, known as "Proposition 65 lawsuits," where interest groups file mass litigation to obtain financial settlements from companies, regardless of the actual risk of exposure.


Evolution and Future of Proposition 65

Prop 65 has been revised and adjusted several times since its implementation to improve its effectiveness and respond to criticism. Recently, the regulations have been updated to make warnings more specific, indicating the chemicals involved and potential health effects.

Going forward, Proposition 65 is expected to continue to be a powerful tool in protecting public health, and other jurisdictions may consider adopting similar legislation.


At the same time, the law will continue to evolve in response to the concerns of both consumers and businesses, balancing the need for clear and effective warnings with protection against excessive litigation.



Conclusion

California's Proposition 65 has set an important precedent for regulating hazardous chemicals in consumer products.


Through its focus on transparency and prevention, it has incentivized companies to reformulate products to avoid public health risks and empowered consumers with valuable information about potential exposures. Despite criticism of warning overload and litigation, this law remains a fundamental pillar of environmental and health protection in the state of California.


For businesses, compliance with Prop 65 is not only a legal imperative, but also an opportunity to improve the safety of their products and contribute to public health. For consumers, the law remains a key tool for making informed decisions in a market saturated with potentially risky products.
