A number of biscuits and snacks sold in the supermarket chain Aldi may have been contaminated by pests, the Food Standards Agency (FSA) has warned.

Customers are being urged not to eat the affected products, made in a factory on Teesside.

The biscuits, including cheese thins, shortbread, chip cookies and fudge brownies, were made by a company called Baketime, based in Middlesbrough.

"There has been no evidence of any contamination", it said.

But Baketime confirmed it had seen "evidence of pest activity" in January and again in March.

"We continue to work closely with our local environmental health officer and pest control contractor to ensure that the issue has been properly eradicated and hygienic standards on site are upheld," the company said in a statement.

Baketime, based at South Tees Imperial Food Park, said it was recalling all the biscuits and snacks as a precautionary measure. In the meantime they were being taken off sale.

The products are sold in Aldi and in small convenience stores around the UK.

The FSA said the biscuits and snacks had been manufactured in "unhygienic conditions", and that it was investigating further.
