Tesco and M&S are recalling five food products after salmonella contamination fears, food outlets report. Customers are told not to eat the affected items and to either return them for a full refund. The affected products include a range of ready meals, salads and sauces.

Outlets also say the Food Standards Agency (FSA) issues the warning to alert consumers to the potential risk. One report adds that shoppers may need to take precautions if they have eaten the products, describing an instruction to isolate for a period of time. The recall is presented as an urgent consumer safety measure while the companies and regulators investigate and advise on next steps.
