1. What is Proposition 65 and Why Does It Matter?

Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a California law designed to protect the state’s citizens and drinking water sources from chemicals known to cause cancer, birth defects, or other reproductive harm. According to research from the University of California, Berkeley, in July 2025, P65 significantly increased awareness of chemical exposure risks.

Understanding the Core of Proposition 65

• Right to Know: Prop 65 mandates that businesses inform Californians about potential exposures to listed chemicals in their products or environment.
• Wide Scope: The list includes approximately 900 chemicals, encompassing substances found in food, consumer products, and workplaces.
• Warning Requirement: If a product exposes individuals to a listed chemical above a certain threshold, a clear and reasonable warning is required.

Why Should You Care About Proposition 65?

• Informed Choices: Prop 65 empowers you to make informed decisions about the products you consume and the environments you frequent.
• Increased Awareness: It raises awareness about the presence of potentially harmful chemicals in everyday items.
• Manufacturer Accountability: Prop 65 holds manufacturers accountable for the safety of their products and encourages them to reduce or eliminate harmful chemicals.

2. What Types of Foods Commonly Carry Proposition 65 Warnings?

Many types of foods can carry Proposition 65 warnings due to the presence of naturally occurring chemicals, contaminants from the manufacturing process, or chemicals produced during cooking. Díaz Leiva mentioned that foods may be labeled due to toxic chemicals from manufacturing or cooking, or naturally occurring chemicals like lead in soil.

Common Food Categories with Prop 65 Warnings:

Examples in Detail:

• Root Vegetables: These can absorb lead or cadmium from the soil in which they are grown.
• Fish: Certain types of fish accumulate mercury in their flesh.
• Coffee: The roasting process can create acrylamide.
• Imported Foods: May contain trace amounts of heavy metals due to varying agricultural practices.
• Supplements: Can be contaminated with heavy metals or other harmful chemicals during manufacturing.

3. How Concerned Should You Really Be About Prop 65 Warnings on Food?

The level of concern you should have about Proposition 65 warnings on food depends on various factors, including your individual health status, frequency of consumption, and the specific chemical in question. Gleason suggests that consumers should make their own choices after considering the information provided.

Factors Influencing Your Level of Concern:

• Individual Health Status: Pregnant women, nursing mothers, and infants are generally more vulnerable to the effects of chemical exposure.
• Frequency of Consumption: Occasional consumption of a food with a Prop 65 warning is less concerning than regular, high-volume consumption.
• Specific Chemical: The toxicity and potential health effects of different chemicals vary. Some chemicals pose a greater risk than others.
• Exposure Level: The actual amount of the chemical you are exposed to matters. Many Prop 65 warnings are for very low levels of chemicals that may not pose a significant risk.

Expert Perspectives:

• Michael J. Gleason: “Californians can’t avoid Prop 65 warnings—they’re on every gas station pump, every hotel, every amusement park in the state. People still go on with their lives and make the choice to go to a restaurant, for example. Like all food labels, they’re intended to provide information.”
• Jimena Díaz Leiva, Ph.D.: “In our day-to-day lives, we’re being exposed constantly to things in our immediate environment and in the food we eat. So it’s really dependent on who you are and what your particular concerns are.”

4. What Are the Specific Chemicals of Concern Mentioned in Prop 65 Warnings?

Proposition 65 covers around 900 different chemicals known to cause cancer, birth defects, or other reproductive harm. The most common chemicals of concern found in food products include lead, mercury, cadmium, and acrylamide.

Key Chemicals and Their Potential Sources:

Understanding the Risks:

• Lead: Even low levels of lead exposure can be harmful, especially for children and pregnant women.
• Mercury: High levels of mercury can damage the nervous system and brain.
• Cadmium: Long-term exposure to cadmium can lead to kidney and bone problems.
• Acrylamide: While acrylamide has been shown to cause cancer in animals at high doses, the risk to humans from dietary exposure is still being studied.
• PFAS: These chemicals are highly persistent in the environment and can accumulate in the body over time, potentially leading to adverse health effects.

5. What Does “Naturally Occurring Chemicals” Mean in the Context of Prop 65?

“Naturally occurring chemicals” refer to substances that are present in food products due to natural environmental factors rather than intentional addition or contamination during processing. Díaz Leiva mentions that sometimes they’re what the state calls ‘naturally occurring chemicals,’ things like lead that might be in the soil.

Examples of Naturally Occurring Chemicals:

• Lead in Soil: Lead can be naturally present in soil and absorbed by plants, especially root vegetables like sweet potatoes and carrots.
• Arsenic in Rice: Rice plants can absorb arsenic from the soil, particularly in areas with a history of pesticide use or natural arsenic deposits.
• Mercury in Fish: Fish can accumulate mercury from their environment, especially larger, predatory fish that consume smaller fish.

Why is This Important?

• Unavoidable Exposure: It’s often impossible to completely avoid exposure to naturally occurring chemicals in food.
• Risk Management: Understanding the sources of these chemicals allows you to make informed choices to minimize your exposure.
• Balanced Diet: A varied and balanced diet can help reduce your overall risk by limiting your intake of any single food source.

6. How Do High-Temperature Cooking Processes Affect the Presence of Harmful Chemicals in Food?

High-temperature cooking processes, such as roasting, toasting, frying, and baking, can lead to the formation of acrylamide, a chemical that has been shown to cause cancer in animals at high dosages. According to the Food and Drug Administration, acrylamide is a human health concern.

The Science Behind Acrylamide Formation:

• Maillard Reaction: Acrylamide forms as a byproduct of the Maillard reaction, a chemical reaction between amino acids and reducing sugars that occurs during high-temperature cooking.
• Starchy Foods: Foods high in starch, such as potatoes, bread, and coffee beans, are more likely to form acrylamide when cooked at high temperatures.
• Factors Influencing Formation: The amount of acrylamide formed depends on the cooking temperature, cooking time, and the specific food being cooked.

Minimizing Acrylamide Formation:

• Lower Cooking Temperatures: Cook foods at lower temperatures whenever possible.
• Shorter Cooking Times: Avoid overcooking foods, as longer cooking times increase acrylamide formation.
• Soaking Potatoes: Soaking raw potatoes in water for 15-30 minutes before cooking can reduce acrylamide formation.
• Toasting Bread Lightly: Toast bread to a light golden color rather than a dark brown.

7. Are Foreign-Made Products More Likely to Have Prop 65 Warnings?

Yes, foreign-made products, especially those from East Asia and Latin America, are more likely to carry Proposition 65 warnings due to varying agricultural practices and potential trace heavy metal contamination. Díaz Leiva notes that there’s a lot of labeling on imported ingredients, particularly for trace heavy metal contamination.

Reasons for Increased Labeling:

• Different Standards: Other countries may have different environmental and food safety standards than the United States.
• Agricultural Practices: Some countries may use pesticides or fertilizers that contain heavy metals or other chemicals of concern.
• Manufacturing Processes: Manufacturing processes in some countries may not be as tightly regulated, leading to potential contamination.
• Increased Scrutiny: Imported products are often subject to increased scrutiny and testing for contaminants.

What to Consider:

• Source of Ingredients: Pay attention to the source of ingredients in the products you buy.
• Reputable Brands: Choose reputable brands that have a commitment to food safety and quality.
• Organic Certification: Look for organic certification, which indicates that the product has been produced without the use of synthetic pesticides and fertilizers.

8. What About Supplements? Are They Also Subject to Prop 65 Warnings?

Yes, supplements, including multivitamins and protein powders, can also be subject to Proposition 65 warnings due to potential contamination with heavy metals or other harmful chemicals during manufacturing. According to Díaz Leiva, everything from multivitamins to protein powder could also be labeled because of packaging that might contain forever chemicals.

Common Contaminants in Supplements:

• Lead: Can be present in raw materials or introduced during manufacturing.
• Cadmium: Similar to lead, cadmium can contaminate supplements through raw materials or manufacturing processes.
• Arsenic: Some supplements, particularly those made from seaweed or other marine sources, may contain arsenic.
• Forever Chemicals (PFAS): Packaging materials can sometimes contain PFAS, which can leach into the supplement.

How to Choose Safer Supplements:

• Third-Party Testing: Look for supplements that have been tested by a third-party organization (e.g., NSF International, USP) for purity and potency.
• Reputable Brands: Choose reputable brands that have a commitment to quality and safety.
• Ingredient Sourcing: Research the brand’s ingredient sourcing practices to ensure they are using high-quality, uncontaminated raw materials.

9. What are “Forever Chemicals” (PFAS) and Why Are They a Concern?

“Forever chemicals,” also known as per- and polyfluoroalkyl substances (PFAS), are a group of man-made chemicals that are highly persistent in the environment and the human body. Díaz Leiva adds that supplements could be labeled because of packaging that might contain forever chemicals.

Properties of PFAS:

• Persistence: PFAS do not break down easily in the environment or the human body, hence the name “forever chemicals.”
• Widespread Use: PFAS have been used in a wide range of products, including non-stick cookware, food packaging, and firefighting foam.
• Bioaccumulation: PFAS can accumulate in the body over time, leading to potential health problems.

Health Concerns Associated with PFAS Exposure:

• Immune System Effects: PFAS can weaken the immune system, making individuals more susceptible to infections.
• Thyroid Disruption: PFAS can interfere with thyroid hormone production, leading to thyroid disorders.
• Increased Cholesterol Levels: PFAS have been linked to elevated cholesterol levels.
• Increased Risk of Certain Cancers: Studies have suggested a possible link between PFAS exposure and an increased risk of kidney and testicular cancer.

Minimizing Your Exposure to PFAS:

• Avoid Non-Stick Cookware: Use stainless steel or cast iron cookware instead of non-stick cookware.
• Choose Uncoated Food Packaging: Avoid food packaging that is coated with PFAS, such as some types of microwave popcorn bags and fast food wrappers.
• Filter Your Water: Use a water filter that is certified to remove PFAS.
