The Center for Public Integrity (CPI) has discovered that two groups of common pesticides, generally considered to be "safer" chemicals, are responsible for one quarter of reported human pesticide poisonings, based on the U.S. Environmental Protection Agency's (EPA) own data. CPI spent several years demanding the release of the data through repeated Freedom of Information Act (FOIA) requests. A trade association representing the interests of the consumer specialty products industry denounced the report.
