Interpretive Guideline No. 2012-02, Consumption of Sulfur Dioxide in Dried Fruits

Go to downloads

Under Proposition 65, a warning for exposure to sulfur dioxide (SO2) from consumption of dried fruit is not required because SO2 exposure will be below the proposed Maximum Allowable Dose Level (MADL) when the reasonably anticipated rate of intake by the average user of the product is considered.

The Office of Environmental Health Hazard Assessment (OEHHA) may issue an Interpretive Guideline that interprets Proposition 65 and its implementing regulations, as applied to specific facts.  The Interpretive Guideline reflects OEHHA’s scientific interpretation of the available information as the lead agency for implementation of the Act.

SO2 was listed as a chemical known to cause reproductive toxicity under Proposition 65, effective July 29, 2011.  This interpretative guideline applies only to SO2 in dried fruit resulting from the use of SO2 on fruit during the production process.  This guideline calculates average exposures to SO2 in various dried fruits and compares them to the proposed Maximum Allowable Dose Level (MADL) for the chemical.  Exposures at or below a MADL are exempt from the warning requirements of Proposition 65.
