Parents are being urged to check their children's cots after Australia's national product safety regulator received several reports of potentially dangerous mould.
The Australian Competition and Consumer Commission (ACCC) said people who own a Mocka brand cot, should check the base of the cot.
Several reports of mould growing on the base of some cots have been made to the ACCC.
The cot should not be used if mould is found on the bottom, as the ACCC is investigating whether the mould is dangerous or not.
"If your child is showing symptoms of mould exposure like congestion, sneezing, coughing, respiratory distress, allergies or other irritations, please consult a doctor as soon as possible," the ACCC said.
On Facebook, Mocka also addressed the issue, saying the company takes "great care" to make sure products are designed and made to meet all safety requirements and regulations.
"After recent extreme weather, we received information that some parents found mould appearing on the base of their cots and mattresses," the company said.
"We are very concerned about these reports and want to ensure our Mocka community is updated on the action we have taken and continue to take with regards to this issue."
Mocka said it has commissioned laboratory testing and a detailed investigation is underway. The company is working with the regulators to determine "the factors that may have contributed to mould growth".
"We expect to have the results of this investigation soon," Mocka said.
