SACRAMENTO, Calif. — The California attorney general has filed a lawsuit against four body care household-cleaning product companies, including Whole Foods Market, Austin, Texas, whose products have tested highest for the carcinogenic contaminant 1,4-dioxane. The other companies are Avalon Natural Products, Beaumont Products and NutriBiotic. Under California's Proposition 65, consumer products that contain toxic levels of 1,4-dioxane must have warning labels stating they may cause cancer. "We have conducted our own investigation into the allegations that some of our products contain 1,4-dioxane and do not believe these products represent a health risk or are in excess of California's Proposition 65 safe harbor level for 1,4-dioxane," Libba Letton, a Whole Foods spokeswoman, was quoted in the Los Angeles Times. "We're cooperating with the attorney general's office to resolve the claims as quickly as possible."
