The Food and Drug Administration (FDA) recognizes Diacetyl as generally safe. However, high levels of diacetyl have been linked to flavorings-related lung disease. Diacetyl poses a greater risk of toxicity when it is heated.
Bottom line: Limit your exposure to synthetically flavored butter products.
