Major supermarket chains including Aldi, Tesco, Sainsbury's, and Marks & Spencer have issued urgent recalls for several food products over health concerns. The recalls stem from potential Salmonella contamination and mislabeling issues, such as incorrect 'use by' dates and undeclared gluten. Salmonella can cause severe symptoms like fever, diarrhoea, and abdominal cramps, particularly affecting vulnerable populations such as pregnant women and those with underlying health conditions. The Food Standards Agency (FSA) has released a list of affected items, urging consumers to avoid consuming these products and return them to the store for a refund without needing a receipt. Notably, Marks & Spencer's Authentic Greek Yoghurt with Vanilla has been recalled due to gluten content that was not declared on the packaging, posing a health risk for individuals with gluten intolerance or coeliac disease. Similarly, Aldi's Hot Smoked 2 Salmon Fillets are being recalled due to an incorrect use-by date printed on the packaging, which should be April 25, 2026. Customers are encouraged to check their purchases against the FSA's list for safety.
