Tesco has recalled its Finest Mozzarella Pearls and Pesto Orzo Salad over concerns that it may be contaminated with a potentially dangerous strain of bacteria. The Food Standards Agency (FSA) has confirmed the recall and warned the public about the risks.
The concern centres on the possible presence of Shiga toxin-producing E. coli, commonly referred to as STEC. The FSA says anyone who has bought the product should not eat it and should return it to any Tesco store for a full refund.
FSA warning and symptoms
In its official notice, the FSA warned: "Symptoms caused by STEC organisms include severe diarrhoea with or without blood in the stool, abdominal pain, vomiting, dehydration and sometimes haemolytic uremic syndrome (HUS), a serious condition that can lead to kidney failure and can be fatal."
Anyone already experiencing those symptoms is advised to keep away from work, school or nursery until they have been clear of illness for at least 48 hours.
Tesco's recall notice
Tesco has also issued its own notice, which is being displayed in stores across the country. The supermarket confirmed: "We're recalling three date codes of Tesco Finest Mozzarella Pearls and Pesto Orzo Salad 215g.
"This is due to the possible presence of Shiga toxin-producing E. coli (STEC), which can cause illness if eaten. No other products sold at Tesco are affected by this recall."
For customers seeking further guidance, Tesco directs them to its customer services page at tesco.com/help/contact.
Recalled product details
The recalled product is Tesco Finest Mozzarella Pearls & Pesto Orzo Salad, pack size 215g, with use-by dates of August 25, 26, and 27, 2026.
NHS Inform explains that while most strains of E. coli are harmless and even help maintain a healthy gut, certain types can cause serious illness. STEC is among the most dangerous, producing toxins that can trigger a far more severe reaction than ordinary E. coli strains.
After coming into contact with the bacteria, symptoms can take anything from one to 14 days to develop, though they most commonly appear within two to four days. Symptoms include diarrhoea, stomach cramps, vomiting, fever, and bloody diarrhoea.
Most people make a full recovery within five to seven days, but some can feel unwell for up to two weeks. The greatest cause for concern is a complication known as haemolytic uraemic syndrome (HUS). NHS Inform notes: "A small number of people, mainly children, with STEC infection go on to develop a serious life-threatening condition called haemolytic uraemic syndrome (HUS)."
Symptoms of HUS include peeing less, pink or brown urine, tiredness, swelling, and bruising. This can sometimes lead to kidney failure and death, although this is rare. The risk of HUS is highest in children aged under five years.
