More salmonella! As someone with a compromised immune system, it’s now pretty scary to get these warnings.

Federal food safety officials warned Monday that consumers should stop eating all foods containing pistachios while they figure out the source of a possible salmonella contamination.

Though, the evidence that it’s salmonella seems pretty thin:

Two people called the FDA complaining of gastrointestinal illness that could be associated with the nuts, but the link hasn’t been confirmed, Acheson said. Still, the plant decided to shut down late last week, officials said.

If they’re not sure it’s the nuts, why start a recall?
