Tesco has recalled a range of flavoured butters amid fears they contain a food poisoning bug.

The supermarket giant said the butters may be contaminated with high levels of Listeria monocytogenes.

This is a bacteria that can cause Listeriosis and may lead to conditions including meningitis.

Four of the butters are sold in 100g packs, while the other three are complimentary discs offered to customers at fresh meat and fish counters.

Recalling the product, Tesco said on its website: "We have been made aware that some Tesco butters may have levels of Listeria monocytogenes present.

"As a precautionary measure, we are recalling all date codes of affected butters from customers."

A spokesman for the retailer told ITV News: "Customers who have purchased any of the affected products should return them to store for a full refund."
