The widow of the man that released 56 exotic animals from their cages and then killed himself was denied retrieving the remaining six live animals Thursday due to a quarantine order from the Ohio Department of Agriculture.
The animals are held indefinitely at the Columbus Zoo under the order issued by Agriculture director James Zehringer.
Zehringer was led to believe that the animals should be examined for potentially dangerous diseases such as the herpes B virus, the Columbus Dispatch said.
There was also concern for the unsanitary living conditions of their homes before their release that could have exposed these diseases to the animals, Star Tribune said.
"These animals are the innocents in this situation, and our job is to really take care of them as much as we can and make sure their welfare is looked out for," Zoo president Dale Schmidt said to Star Tribune.
