(CBS NEWS) NEW YORK -- Several agencies have joined forces as part of an investigation into the discovery of a dead bat that was allegedly found in a packaged salad in Florida, authorities said.

The Centers for Disease Control and Prevention said in a media statement that two people reported eating some of the salad before finding the animal.

Authorities say the bat was sent to the CDC rabies lab for testing.

“The deteriorated condition of the bat did not allow for CDC to definitively rule out whether this bat had rabies,” the statement indicated.

Following the incident, Fresh Express issued a recall on Saturday of a limited number of cases of Organic Marketside Spring Mix out of an abundance of caution.

What to look for on recalled product:

• Organic Marketside Spring Mix -- 5 oz. clear container

According to the CDC, the salads were distributed to Wal-Mart stores located in the Southeastern region of the U.S.
