AN apple and blackcurrant squash has been withdrawn from the shelves of Tesco in Henley.
It comes after a flavour additive was introduced to the product by mistake.
A Tesco said a "few" customers had made returns to the Reading Road store.
He said: "We have investigated with our supplier complaints about 'Tesco no added sugar double concentrate apple and blackcurrant', 750ml and 1.5l.
"A flavour additive, which is not part of the ingredients for this product, has been added in error. The additive is called dimethyl disulphide and is a common ingredient in food products.
"It is an approved additive and poses no food safety risk. However, it does have a strong odour, similar to garlic which customers are likely to find unpleasant.
"We have withdrawn the product from sale. Only products bought since the New Year may be affected. They will have a best before date of October 2015."
Customers can return the product, open or unopened to any Tesco store.
