Public Health - Seattle & King County

Artificial trans fat

  • Starting May 1, 2008
    The first phase to eliminate trans fat in King County applies to fry oils and shortenings, used for deep frying. All food establishments with operating permits from Public Health - Seattle & King County are required to stop using oils or shortenings that contain partially hydrogenated oil - also called artificial trans fat - for deep frying or in spreads. The exception to this is the deep frying of yeast dough or cake batters, such as donuts.

  • Starting February 1, 2009
    Food establishments must not store, use, distribute or serve any products containing artificial trans fat, except if served in the original package, such as potato chips, by February 1, 2009. Food establishments need to identify healthy alternatives for margarines, oils and shortening used for preparation of all other foods, including baked products, deep frying of yeast dough and cake batter. The regulation requires that artificial trans fat must be less than 0.5 grams per serving.
