Dead rats, rodent paw marks, gnaw marks on coffee bean bags and maggots in fish were among the reasons the Food Safety Authority of Ireland issued 17 enforcement orders on food businesses in October.
FSAI CEO Dr Pamela Byrne said 17 orders was the highest number served in a month to date this year, and the figure included 14 closure orders.
The FSAI said some of the reasons for the enforcement orders included finding two dead rats in a dry goods storeroom, the presence of rodent paw marks on dusty shelves and gnaw marks on coffee bean bags.
The authority also found rust and dirt inside a meat mincing machine in one premises and an absence of staff food hygiene training records for all food handlers in another.
In one premises management were unable to provide answers in relation to two complaints received regarding maggots in fish.
The authority also said management could not provide any information in relation to traceability of the fish or where the rest of it had been disposed.
Dr Byrne reiterated the need for food businesses to have adequate pest control systems in place and added businesses must operate strict food safety procedures at all times.
She said: "As in recent months, a high number of the Enforcement Orders were associated with issues related to pests and failures in basic staff training.
"These issues are all preventable and food businesses must ensure that they always adhere to a high standard of food safety and hygiene."
