A public apology has been made to a woman, bitten by a wild ferret during her stay at Gosford Hospital on the New South Wales Central Coast late last year.

The local health district has confirmed a ferret found its way into the hospital's short stay unit in the early hours of November the 13th and latched onto the woman's hand when she tried to catch it.

A spokeswoman said the patient was treated for bite wounds and received a tetanus injection as a precaution.

At the time, she received a verbal apology from the Acting Director of Nursing and Midwifery.

Central Coast Health has now made that a public apology for any distress the matter caused.

An investigation found the hospital's pest control measures were sufficient at the time.
