Five varieties of Kettle Chips are being recalled because of fears the products may contain pieces of plastic. The Food Standards Agency (FSA) said: "This means these products are a possible risk to health."

The five varieties listed for recall are Lightly Salted 150g; Sea Salt & Balsamic Vinegar 40g; Mature Cheddar & Red Onion 40g; Lightly Salted Multipack (5 x 30g) and Lightly Salted 30g. All of the recalled varieties carry the best before date 28 May 2016.

Kettle Foods Ltd. said they had "identified that a very limited number of bags of KETTLE® Chips products, all with a best before date of 28th May 2016, may contain pieces of plastic that are similar in appearance to the crisps."

"As a precautionary measure, we are asking customers not to eat the product and to contact us for a full refund."

"We apologise for any inconvenience caused and thank our customers in advance for their cooperation."

The FSA gave this advice to customers who may have been affected:

"If you have bought one of the above products, do not eat it. Instead, post the empty pack, together with your name and address to Kettle Foods Ltd at:

Kettle Foods Ltd
Barnard Road
NR5 9JP"
