14 Aug 2013 --- D.D. Williamson (DDW) announces that its natural coloring manufacturing site — located in Port Washington, Wisconsin — is officially certified by the Global Food Safety Initiative (GFSI). GFSI is widely considered to be the “gold standard” for international food safety. DDW has added to last year’s achievement of GFSI certification at all caramel color production facilities to place the company at the leading edge of advanced food safety practices.
