Sainsbury's and Spar have withdrawn products because of incorrect allergen labelling information.

Sainsbury's has recalled all date codes of its six-pack Sausage and Tomato flavour crisps because the product contains lactose, which was not declared on the label. It has also recalled all date codes of its six-pack roast chicken flavour crisps because it contains whey protein, which was not labelled.

Spar has withdrawn three varieties of its own-label flapjacks 90g because the products contain soya and/or sulphites not declared on the ingredients list.

The affected products are Spar Chocolate Flavoured Top Flapjack 90g, Spar Caramel Flapjack 90g and Spar Bakewell Flapjack 90g, all batch codes and best before dates.
