4-hydroxystyrene occurs frequently in different ciders, wines, foods and berries, e.g. cloudberry. Styrene is a prohapten metabolized in the skin by aryl hydrocarbon hydroxylase (AHH, EC 1.14.14.1) to styrene epoxide acting as the true hapten. Styrene occurs in nature and as a synthetic product.(PMID: 6713846). 4-Vinylphenol is found in many foods, some of which are asparagus, highbush blueberry, tea, and beer.
