The 35-page complaint says Kerrygold butter, sought after for its rich flavor and creamy texture attributed to grass-fed cows, is falsely advertised as “Pure Irish Butter” given that the sticks contain per- and polyfluoroalkyl substances (PFAS), man-made chemicals known to be harmful to humans and the environment.

The quality of the milk used in Kerrygold and the higher fat content does impact recipes. This butter is often more flavorful thanks to the grass the cows eat, so Irish butter can provide more buttery flavor recipes.

It stated: "Kerrygold butter is graded, produced and packaged in Ireland. We are currently working with the Wisconsin authorities on a solution which will enable consumers throughout the state enjoy the great taste of Kerrygold butter."

Kerrygold products are not organic, and Kerrygold does not seek to apply that label to our products. Like organic farmers, Irish dairy farmers' practices promote healthy nutrient rich soil; encourage wildlife which naturally controls pests and our farmers place animal welfare at the heart of our farming traditions.

Because the remaining percentage in butter contains mostly water, it takes away the flavor and creaminess of the butter. Even though the butters can be used interchangeably, Irish butter has a higher fat and lower water count than American butter, so it has a better taste and makes it a better choice for baking.

Irish butter is delicious over fresh corn and other simply steamed vegetables. Bakers can use Irish butter in cakes and cookies, as it makes for an especially flaky pastry crust, is great in butter cookies, and takes Rice Krispies treats to a whole new level.

The difference between organic butter and non-organic butter is just that organic cream is used rather than standard cream. The energy and fat content is no different - it just means that it has been produced from cream has been sourced from a cow which has been raised and fed on organic pastures.
