New tests that promise to speed up diagnosis of food poisoning pose an unexpected problem: They could make it more difficult to identify dangerous outbreaks like the one that sickened people who ate a variety of Trader Joe's peanut butter this fall.

It's about to get faster and easier to diagnose food poisoning, but that progress for individual patients comes with a downside: It could hurt the nation's ability to spot and solve dangerous outbreaks.
Unless one is found, the CDC's Dr. John Besser said the tests' unintended consequence could be that ultimately, more people become sick.
"These improved tests for diagnosing patients could have the unintended consequence of reducing our ability to detect and investigate outbreaks, ultimately causing more people to become sick," said Dr. John Besser of the CDC.
