Tesco recalls Finest pasta salad over E. coli: why this strain matters

Tesco has pulled a Finest pasta salad from shelves over possible E. coli contamination, and because the earliest affected use-by date had already passed when the alert went out, some shoppers may have eaten it first. Here’s what the recall means and why the strain involved is the one to take seriously.

On 25 August 2026 the Food Standards Agency published Tesco’s recall of Tesco Finest Mozzarella Pearls & Pesto Orzo Salad (215g), over the possible presence of Shiga toxin-producing E. coli (STEC). The recall covers three use-by dates: 25, 26 and 27 August 2026. Shoppers are told not to eat it and to return it to any Tesco store for a full refund, no receipt needed.

Why STEC is not a run-of-the-mill tummy bug

Most E. coli is harmless. STEC is the exception, and it is why the FSA treats a recall like this as urgent. It can cause severe stomach cramps and bloody diarrhoea, and in a minority of cases, particularly in young children and older people, it can lead to haemolytic uraemic syndrome (HUS), a serious complication that can cause kidney failure and can be fatal. That is the reason the advice is not “eat around it” but “do not eat it, return it.”

The timing is the uncomfortable part. The earliest affected use-by date, 25 August, had already passed by the time the alert was public, so some customers may have eaten the product before being warned. If you bought this salad, check your fridge now; if you’ve already eaten it and feel unwell, the FSA advises staying away from work, school or nursery until 48 hours after symptoms stop, to avoid passing it on.

A recall is the system working, but a use-by date that has already passed is a reminder of how little time there is between a shelf and a plate.

Where a recall fits alongside a hygiene rating

A product recall and a venue hygiene rating are different tools, but they point at the same thing: control of the food chain. A recall catches a problem at the manufacturing or supply stage; a hygiene rating measures how well the place serving you handles food, including whether it acts on alerts like this one, checks stock against recall notices, and removes affected product. A well-run kitchen sees an FSA recall and acts on it the same day. That responsiveness is part of the “confidence in management” an inspector assesses.

Recalls come and go; what stays is how a business responds to them. The venues at the top of the scale are the ones with the systems to catch an alert and act; the tail is where those systems are weakest.

What to do

If you have the affected salad (Tesco Finest Mozzarella Pearls & Pesto Orzo Salad, 215g, use-by 25/26/27 August 2026), do not eat it, return it to any Tesco store for a full refund. If you’ve eaten it and have symptoms, particularly severe cramps or bloody diarrhoea, seek medical advice via NHS 111 and stay off work or school until 48 hours after symptoms clear.
