In October, the company announced it was no longer going to purchase milk from a farm owned by President Robert Mugabe's wife Grace.
The BBC
reports the company says since making this announcement, it is has been under pressure to accept milk from "certain non-contracted suppliers".
"Two Nestle Zimbabwe managers were questioned by the police and released without charges the same day," Nestle said in a statement.
"Since under such circumstances normal operations and the safety of employees are no longer guaranteed, Nestle decided to temporarily shut down the facility."
Nestle decided it would no longer buy milk from Gushungo Dairy Estate after human rights activists had called for a boycott of Nestle products.
Grace Mugabe took over the ownership of the dairy operation after it was seized from its white owner under controversial land reforms.
