The products, made by Baketime Ltd, have been withdrawn from sale “on a precautionary basis” due to “potential unhygienic manufacturing conditions”, the recall notice said.
Customers who have purchased products were warned not to eat the goods and to return them to their nearest store.
Affected products include Aldi Cheese Thins, Aldi Cheese Bakes, Aldi Oddbites and Aldi Ginger Nuts.
Aldi Australia said the recall does not affect any stores in the Australian market. An Aldi UK spokeswoman said all orders with the supplier had been suspended while the matter was investigated.
Baketime confirmed that its premises in South Bank, Middlesbrough has an, “issue with pest activity”.
The manufacturer said this was first identified in January and that it took “immediate steps” with help of a pest control company to, “manage the situation and eradicate it as quickly as possible.”
However, further evidence of pest activity was identified this month, “and an intense programme of pest control measures was again implemented”, Baketime said in a statement. Baketime volunteered to stop production temporarily for a routine site inspection.
