Fourteen food outlets were ordered to close last month due to issues including dead rats in a dry goods storeroom, rodent paw marks on dusty shelves and gnaw marks on coffee bean bags.
They include a restaurant and a takeaway in Dublin, a takeaway in Roscommon, another in Cork and a restaurant in Meath.
The Authority also issued 17 enforcement orders, which is the highest in a month so far this year. FSAI chief Dr Pamela Byrne described it as "an unacceptable number".
She added: "It is imperative that a proper pest control system is in place and that this is checked very regularly in order to avoid infestations of rodents and insects.
"With the busy Christmas period nearly upon us, food businesses must be especially vigilant to ensure compliance with the law and to protect the health of their customers.
"Special attention should be given to food safety training for both full and part-time staff to cope with any extra demand."
