Sulfur dioxide was recently added as a Proposition 65 chemical that could require warnings to consumers and employees as a chemical that may cause reproductive effects. The listing of sulfur dioxide will be particularly troublesome because sulfur dioxide is used as a fumigant and preservative on a number of fruits, including grapes and in related food products, such as wine. Please see our recent blog entitled, "Sulfur Dioxide Added to Prop 65 Could Have Broad Range of Impacts" and California Grape and Fruit Tree League comments for additional information.
