EPA: saccharin not a health threat

摘要

The Environmental Protection Agency is taking saccharin and its salts off its list of hazardous substances. According to the agency, the crystalline powder "is no longer considered a potential hazard to human health." Saccharin was first listed as a hazardous waste in 1980 after studies in rats showed the sweetener caused higher rates of bladder cancer. The EPA subsequently determined it to be a "potential human carcinogen". Yet two decades later, the National Toxicology Programme and International Agency for Research on Cancer reversed that classification after scien- tists failed to link saccharin consumption to cancer in humans.
