Are chicken livers that are brown rather than pink still good?

It depends. Chicken livers can vary in color naturally, and sometimes they may appear brown due to oxidation or storage conditions. If the livers smell fresh, are firm and spring back when touched, and have no signs of spoilage such as off odors, sliminess, or mold, then they are likely still good. However, it is always recommended to cook the livers thoroughly to ensure their safety. If the brown color is accompanied by other signs of spoilage, it's best to discard the livers.
