UK supermarkets recall foods over allergens, metal, and salmonella; check labels and return products.

Supermarkets across the UK, including Aldi, Lidl, M&S, Tesco, and Iceland, are recalling various food products due to safety risks. Aldi is recalling beef steaks and custard tarts over undeclared allergens like milk, egg, wheat, and nuts. Lidl issued a "do not eat" warning for its Stroopwaffel due to possible metal fragments. M&S is recalling milk chocolate honeycomb for undeclared peanuts. A dog food brand is also being recalled over salmonella contamination. Consumers are advised to check batch codes and best-before dates, avoid the products, and return them for refunds. The Food Standards Agency confirms only these items are affected.
