In the most recent case, a man living in the Rockdale Road area confronted the raccoon that was behaving aggressively on July 24, said Pam Tucker, the director of the county’s Emergency and Operations Division.
The raccoon, which had no direct contact with the man or any animals, was shipped for testing Monday.
In the first three incidents, dogs came into contact with raccoons later found to be rabid. All three cases were near Harlem.
The dogs in the first two incidents did not have up-to-date vaccinations and were euthanized, prompting Columbia County public health officials to advise residents to make sure their animals are vaccinated against rabies.
