Tesco and Superdrug are both recalling products because they may contain small pieces of metal.

An alert issued by the Food Standards Agency because the items are 'unsafe to eat', says customers with any of the affected items should not eat or drink them and instead take them back to the shop they were brought from for a full refund.

Tesco is recalling packets of its Tesco Active Strawberry Flavoured Whey Protein and Tesco Active Chocolate Fudge Flavoured Whey Protein, a supplement often popular with people doing a lot of exercise who are trying to increase muscle mass.

The 500g pack sizes, which are included in the recall, all have best before dates of May 31, 2024.

The supermarket giant, which has also put notices in store aisles to alert shoppers, says any customer with the whey protein at home can return it to Tesco without a receipt for a full refund.

High street store Superdrug is also recalling a range of its meal replacement shakes because they too could contain small pieces of metal inside.

Anyone with the Slenderplan Tropical Smoothie Meal Replacement Shake, which comes in eight 26g sachets with a best before date of May 31, 2023, should not drink it and instead take it back to a Superdrug shop.
