Free the Sudan-1 The guys at Lea & Perrins are understandably cheesed off with the Sudan dye scare as Worcester sauce is noted as the primary source (no pun intended) of the banned colourant. L&P’s famous ingredient for Bloody Marys does not and never has contained the dye but the problem centres around their rival Premier Foods' chilli powder, which was used in a Worcester sauce then used to make other products. Small consolation for the thirty-five employees of Lea & Perrins who’ve been making the famous sauce since 1835.
