Coffee makers, especially those of the Ninja brand, are some of the most popular coffee makers on the market. This is because they are easy to use, provide excellent quality coffee, and are relatively affordable. However, many users may not realize that some of these coffee makers come with a warning label: “This product contains chemicals known to the State of California to cause cancer, birth defects, and other reproductive harm.” While it might be a shock to learn that your coffee maker could pose a potential health risk, knowing the facts is essential to make an informed decision. This blog post will explore why Ninja coffee makers come with a cancer warning and what you can do to protect yourself.

The Ninja Coffee Maker has a cancer warning as a result of acrylamide, a chemical compound found in coffee. Studies have linked the presence of acrylamide in coffee to an increased risk of developing cancer. While this risk is relatively small, the California Office of Environmental Health Hazard Assessment (OEHHA) has deemed it necessary to inform consumers of the potential risk. Therefore, the Ninja Coffee Maker is labeled with a cancer warning in accordance with OEHHA guidelines.

Ninja Coffee Makers Have High Levels of Acrylamide

Recently, the California Environmental Protection Agency has warned that Ninja coffee makers have been found to have elevated levels of acrylamide in their brewed coffee. Acrylamide is a chemical that is classified as a probable carcinogen, meaning it can be linked to an increased risk of cancer. While the amount of acrylamide found in the coffee brewed by Ninja coffee makers is below the safe limits set by the EPA, it is still higher than the amount found in coffee from other manufacturers. As such, the California Environmental Protection Agency has issued a cancer warning on Ninja coffee makers to inform consumers of the elevated risk.

Acrylamide is a byproduct of the Coffee Roasting Process

In the process of coffee roasting, the beans are exposed to high temperatures that can cause acrylamide formation. This chemical is classified as a potential carcinogen. This byproduct can be found in other coffee brewers as well. Still, Ninja Coffee Makers are subject to additional warning labels as they are used with a higher temperature setting than other machines. The high temperature combined with long roasting times can increase the formation of acrylamide, which is why Ninja Coffee Makers are required to have a cancer warning.

The FDA Recommends Reducing Acrylamide Exposure

The Food and Drug Administration (FDA) recommends reducing exposure to coffee makers containing acrylamide when possible. The Ninja Coffee Makers have a cancer warning displayed on their product due to their potentially high levels of acrylamide. The FDA recommends selecting a low-acrylamide coffee to reduce the potential exposure to this potential carcinogen. Consumers should also be aware that coffee makers that use paper filters can reduce the acrylamide levels in coffee.

Follow The Instructions Included With Coffee Makers

To reduce acrylamide exposure from brewed coffee, it is crucial to follow the instructions included with the coffee maker. Acrylamide is a chemical compound formed when starchy food is cooked at high temperatures and is thought to be a potential health hazard. While research is ongoing, it is best to take precautionary measures to reduce exposure to acrylamide. Following the instructions provided by the coffee maker will help to reduce the risk of acrylamide exposure from brewed coffee.


In conclusion, it is essential to remember that a cancer warning on Ninja coffee maker products does not necessarily indicate heightened cancer risk. Instead, the presence of the warning is a product of California’s Proposition 65, which requires products containing certain chemicals to be labeled with a warning to inform consumers of potential risks. Despite the warning, Ninja coffee makers remain a popular and convenient way to make your morning cup of coffee.
