Workers at the zoo in the central Germany city of Erfurt are being accused of shooting animals and selling their meat without permission.
A spokeswoman for the town's mayor says the animals included deer, ITV News reported Wednesday.
"The case is now with the state prosecutors," she said.
The German Animal Protection League is demanding a review of controls at the zoo, as well as others in the state of Thuringia.
"We are worried this is only the tip of the iceberg," league President Wolfgang Apel said.
Erfurt Zoo has lions, elephants and giraffes among other animals. It has been the target of complaints from animal rights activists and federal authorities over its imports of South American wild elephants.
