“Two people in Florida reported eating some of the salad before the bat was found," reads the agency's notice of an investigation of the incident.
The dead bat was turned over to the federal government.
“The deteriorated condition of the bat did not allow for CDC to definitively rule out whether this bat had rabies."
That sounds bad, though the CDC offers reassurance that the chance of a live rabies virus making its way into the salad is very small.
And the two people who ate the salad appear healthy.
“Immediately upon notification of the event, Fresh Express food safety and rapid response teams worked in close coordination with Walmart and regulatory authorities to launch an intensive investigation," a spokesperson for the company, which is owned by Chiquita of bananas fame, wrote in a statement to The Washington Post.
“Based on all available evidence, we are confident this is an isolated incident."
A Walmart spokesperson didn't say in which store the bat was found, but said that as soon as the company learned of the incident, it told all stores selling salad from that batch to pull it off the shelves.
There are no signs that the incident will lead to anything like the public relations crisis that Chipotle faced in 2015, when 80 college students fell ill after visiting a single restaurant.
A decomposed bat is not even necessarily the grossest extraneous matter you can find in your dinner.
