There are more FDA Outbreak Investigations closed with no answers, in the just updated FDA CORE Outbreak Investigation Table. So far nine outbreaks this year have ended unsolved.

For the two Cyclospora outbreaks, the outbreaks are over and the investigations have closed with no answers.

Traceback has been initiated in that … [Read more...]
