Please Note: If you look on the packaging, you will see a warning on the label, which states:

What does that mean if no nuts are used in the ingredients of the Kit Kat Bar? We take a deeper look at it below.

Do Kit Kat Chocolate Contain Nuts/Peanuts?

In Canada, tree nuts and peanuts are priority allergens, which means that Canadian labeling regulations require them to be declared in the ingredient list (if it’s part of the product) or under a “May Contain” statement (if there is a chance for cross-contamination) on the label. If they are not listed, the product does not contain nuts.

What Does May Contain Nuts, Peanuts Mean on Candy Bars?

Do you have a severe nut allergy?  If you look on the Kit Kat chocolate bar label, you will see “May Contain Nuts, Peanuts.” But what does that actually mean?

The FDA defines “may contain” as:” A food allergen labeling statement that warns consumers that a food product was manufactured on shared equipment and may contain trace amounts of an allergen.” So, even if a product doesn’t have any nuts or peanuts listed as an ingredient, there’s still a chance that it was contaminated during manufacturing.

A Quora post from 2016, gives us another look at why Kit Kat’s have that warning label.

As you can see, most big companies have production plants in which many different things are made at the same time, and there is always a chance that particles from an allergen like nuts could contaminate other foods.

Wrapping it up

We’ve reached the end and as you can see, the answer to “Do Kit Kats Have Peanuts” is no. The ingredients in a Kit Kat chocolate bar do not list peanuts or nuts.

However, there is a warning label that states “May Contain Nuts, Peanuts.” This means that there is a chance that the product was contaminated with nuts during manufacturing.
