On many chili oil and chili crisp jars, you'll see a reference to California Proposition 65. Sometimes, you'll even see a notation "Not for sale in California". California is known for regulatory legislation which can often exceed the requirements set by federal agencies such as the FDA. Here's a breakdown of what Prop 65 entails and how it relates to the sale of chili oil and chili crisp products in the US:
California Proposition 65 (officially the Safe Drinking Water and Toxic Enforcement Act of 1986) requires businesses to provide a warning before exposing consumers to certain chemicals that the state has identified as causing cancer, birth defects, or other reproductive harm. The law applies to products sold in California, even if they are manufactured elsewhere.
For chili oils and chili crisp condiments, Proposition 65 has become a significant labeling and compliance issue, even though the products remain legal to sell.
Why chili oils and chili crisps often carry Prop 65 warnings
Several chemicals commonly associated with chili-based condiments can trigger Proposition 65 concerns:
1. Lead
Lead is probably the most common reason for a Proposition 65 warning on chili crisp products.
Trace amounts of lead can occur naturally in agricultural soils and can be absorbed by chili peppers and other ingredients. Lead may also enter the supply chain through environmental contamination, drying processes, or imported spices. Proposition 65's allowable exposure levels for lead are extremely low, so even tiny amounts can trigger warning requirements.
This is why consumers frequently see warnings such as:
"Consuming this product can expose you to chemicals including lead..."
on jars of chili crisp, chili oil, and spice blends.
2. Cadmium
Cadmium is another naturally occurring heavy metal that can be present in agricultural products grown in certain soils. California specifically identifies cadmium as a Proposition 65-listed chemical, and foods can contain trace amounts absorbed from the environment.
3. Acrylamide
Acrylamide forms when many plant-based foods are cooked or processed at high temperatures. Fried garlic, fried shallots, roasted peppers, and other browned ingredients commonly found in chili crisp can potentially contain acrylamide. California has long regulated acrylamide under Proposition 65, although warning requirements for food products have evolved through litigation and regulatory changes.
Why some brands have warnings and others don't
This often confuses consumers.
Two jars of seemingly identical chili crisp may be sitting side-by-side on a shelf:
- One has a Proposition 65 warning.
- The other does not.
That does not necessarily mean the warned product contains more lead, cadmium, or acrylamide.
Possible reasons include:
- One company tested its product and determined a warning was prudent.
- One company sells extensively in California while another does not.
- One company uses a warning as a legal precaution.
- One company has conducted expensive exposure assessments showing warnings are unnecessary.
- Different ingredient sourcing can produce different test results.
The presence or absence of a warning is not a direct measure of product safety. Proposition 65 is fundamentally a disclosure law rather than a product-ban law.
Impact on manufacturers and importers
For chili oil and chili crisp producers, Proposition 65 can create substantial compliance costs.
Manufacturers may:
- Test products for lead, cadmium, and other listed chemicals.
- Reformulate recipes.
- Change ingredient suppliers.
- Add warning labels to packaging.
- Face litigation if warnings are deemed insufficient.
- Simply opt to restrict sales into California altogether.
Many imported Asian condiments—including chili crisps from China, Taiwan, Japan, Korea, and Southeast Asia—have received Proposition 65 warnings because of concerns about trace heavy metals in peppers, spices, or other ingredients.
In practice, some companies choose to apply the warning nationwide rather than maintain separate California and non-California packaging.
Impact on consumers
For consumers, the result is that many chili oils and chili crisps sold throughout the United States now carry California-style warnings even when purchased outside California.
This can create the impression that the product is unsafe, but that conclusion is often not warranted.
A Proposition 65 warning means:
- California has identified a listed chemical that may exceed a specified exposure threshold.
- The manufacturer has chosen or been required to provide a warning.
It does not mean:
- The product violates federal food safety standards.
- The product is adulterated.
- The product is illegal to sell.
- The product is known to cause harm when consumed normally.
The warning is intended to inform consumers about potential exposure, not to prohibit sale of the product.
Specific examples in the chili crisp market
Many consumers have noticed Proposition 65 warnings on well-known chili crisp brands, including products from brands such as Lao Gan Ma and Fly By Jing. Public Proposition 65 notices have cited lead exposure concerns for some chili crisp products.
The warnings are generally associated with trace heavy-metal exposure rather than with the chili oil itself.
Practical takeaway
For chili oils and chili crisps, Proposition 65 warnings are most commonly related to:
- Lead in chili peppers or spices.
- Cadmium in agricultural ingredients.
- Acrylamide formed during frying or roasting processes.
The law has significantly influenced labeling, testing, sourcing, and legal compliance for manufacturers selling these products in California. As a result, many jars of chili crisp sold throughout the United States now display Proposition 65 warnings even though the products remain legal under federal food regulations and are consumed routinely by millions of people.
