Tesco and Waitrose are recalling food items over fears they may contain salmonella.

Both supermarkets have issued warnings about items they sell that may contain the bacteria that can cause food poisoning.

Waitrose is recalling its own brand Waitrose & Partners Green Pesto with Basil.
According to an alert issued by the Food Standards Agency, salmonella has been found in the food and customers are being warned to not eat any of the pesto they have at home but to return it as soon as possible to their nearest store for a full refund.

Symptoms caused by salmonella typically include fever, diarrhoea, sickness and stomach pain and according to the NHS website can start anything between a few hours and a couple of days after eating affected food.

While most who suffer from food poisoning will recover within a few days, the elderly, young children and people with compromised immune systems are among those who can be more at risk of complications caused by food poisoning.

Salmonella has been detected in the Waitrose pesto with a use by date of February 27 and the supermarket says it is now displaying sighs in stores to alert customers to the problem and explain why it is being recalled and what to do if they've got affected items at home.

While at Tesco its Hog Roast Style Pork with Apple Sauce is being recalled because the crackling crumb sachet within the pack may contain salmonella, says the Food Standards Agency.

The packets affected by the issue weigh 425g, says the supermarket, and the use by dates of those products affected include February 6, March 8 and March 9.

Tesco, which has also issued a recall notice for the pork, is asking customers to return any they have bought with the affected dates on to their nearest store for a full refund.

The possible presence of salmonella in some infant milk formula powders used under medical supervision have also prompted recalls this week.

Abbott has taken the 'precautionary step', says the Food Standards Agency of recalling various batches of Elecare Similac and Alimentum Similac infant formula powders because they might contain salmonella.

Both products, says the FSA, are foods used for special medical purposes for babies and very young children and shops or pharmacies who distribute the powder have been told.

Any family who thinks they may be affected by the recall can find the exact batches being affected here.
