• FDA warning letters

Public domain (U.S. government work). Letters are as FDA lists them in its warning letters table: the company, the issue and posting dates, the issuing office and FDA's subject line. Subject groups are SpecStream's, read from the words of that subject line. FDA posts a letter some weeks after it issues it, so the newest weeks fill in later.
