Where this comes from
FDA publishes the warning letters it sends. Each row is one letter as the agency posted it: the company it is addressed to, the date on the letter, the date FDA posted it, the office that issued it and the agency's own subject line, with a link to the full letter. A warning letter states the agency's findings at the time it was written; it is not a final determination, and the company may have responded or since corrected the matter. Read the letter, and any response or close-out letter FDA has posted, before relying on it.
