The main purpose of the "Ban Harmful Food Dyes Act" is to improve food safety by prohibiting the use of certain color additives in food products. The act aims to protect public health by classifying these additives as unsafe and adulterated, meaning they are not fit for consumption. Key provisions of the act include a specific list of color additives that will be deemed unsafe for use in food starting January 1, 2027. This list includes well-known dyes such as Red No. 40, Yellow No. 5, and Titanium Dioxide, among others.
