Is mayonnaise exempt from listing ingredients on label?

Mayonnaise is not exempt from listing ingredients on its label. In the United States, the Food and Drug Administration (FDA) requires that all packaged food products, including mayonnaise, include a complete list of ingredients. This labeling helps consumers make informed choices about the food they purchase and consume. However, there may be some exceptions for certain types of foods, but standard mayonnaise sold in stores must have its ingredients clearly listed.
