Two people in Florida ate some salad from a container before discovering the remains of a dead bat inside of it, officials said.

The bat — a Mexican free-tailed bat — was sent last week to a Centers for Disease Control and Prevention laboratory for rabies testing because the animals in the United States can sometimes carry the disease, the agency said in a statement on Saturday. However, the bat was too badly decomposed to definitively determine whether it had rabies.

Transmission of rabies by eating a rabid animal is “extremely uncommon,” the agency said, adding that the virus does not survive for long outside the infected animal.

Florida health officials were evaluating the people who ate the salad. They reported being in good health and neither exhibited any signs of rabies, the C.D.C. said.
