Three food businesses, two of them in Dublin and one in Co Kildare, were served with closure orders by the Food Safety Authority (FSAI) last month.
They included an O'Brien's Irish Sandwich Bar at Unit 116 on the first floor of the St Stephen's Green Shopping Centre in Dublin.
The other two businesses served with closure orders were Gmad Foods Ltd, Ba Mizu, unit 19, Powerscourt Townhouse Centre, Dublin 2, and the Carlton Abbey Hotel (main kitchen) in Athy, Co Kildare.
A closure order is served by the authority where it is deemed that there is or is likely to be "a grave and immediate danger" to public health at or in the premises in question.
The orders can refer to the immediate closure of all or part of the food premises, or all or some of its activities.
In addition to the closure orders, three prohibition orders and one improvement order were served on food premises during the month for breaches of food safety regulations.
The prohibition orders were served on Gmad Foods Ltd, Ba Mizu, Unit 19, Powerscourt Townhouse Centre, Dublin 2; Camillus Cleary butcher shop, Killucan, Mullingar, Co Westmeath; and. Regional Foods Ltd, Simpsons Supermarket, Tul Na Rí, Carndonagh, Lifford, Co Donegal.
Two of the prohibition orders - involving the businesses in Co Westmeath and Co Donegal - referred to the discovery of specified risk material, which should have been removed from animals as part of the controls on BSE, the authority said.
Five beef "bone-in joints" were found in the Carndonagh supermarket, which came from animals that may have been over 24 months of age and might have contained vertebral column, according to the FSAI report.
Beef containing vertebral column was also found on the butcher's premises in Killucan, Mullingar, which was from an animal over two years old and was in breach of the specified risk material regulations.
The improvement order served during the month was on The Ferry Bar and Grocery, Rossport, Ballina, Co Mayo.
A prohibition order is issued if the activities at a premises involve or are likely to involve a serious risk to public health from a particular product, class, batch or item of food. The effect is to prohibit the sale of the product, either temporarily or permanently.
An improvement order may be issued by the District Court if an improvement notice is not complied with within a defined period.
Four closure orders were served on food businesses during the month of September and five during July.
