Sandwiches, wraps and salads sold in UK supermarkets including Sainsbury’s and Asda are being recalled because of a potential link to an E.coli outbreak that left dozens of people in hospital.

Officials said the move by Greencore Group is a “precautionary measure” and came after 211 cases linked to the outbreak were confirmed, dozens of which were admitted to hospital.

The products being recalled include sandwiches, wraps and salads sold at Sainsbury’s, Asda, Aldi, Morrisons, Co-op, retail pharmacy chain Boots, Amazon.

A full list of the products recalled can be found at the bottom of this article.

E. coli are a diverse group of bacteria that are normally harmless and live in the intestines of humans and animals. However some strains, like shiga toxin-producing E.coli (Stec), can make people very ill.

People infected with STEC can suffer diarrhoea, and about 50% of cases have bloody diarrhoea. Other symptoms include stomach cramps and fever.

Earlier this month, UKHSA confirmed at least 113 confirmed STEC cases of which 37 people had been admitted to hospital following the outbreak. As of 11 June, the number of cases had risen to 211. Based on information from 160 cases to date, 42% were admitted to hospital, the UKHSA said.

The UKHSA said genome sequencing of samples indicated most of these cases are part of a single outbreak.

The FSA advises any consumers who have any of the products being recalled not to eat them.

What we don't know

We still don't know for sure the exact source of the outbreak.

Darren Whitby, head of incidents at the Food Standards Agency, described the recall as a "precautionary measure". He said the Food Standards Agency (FSA), Food Standards Scotland (FSS) and UK Health Security Agency (UKHSA) were still working to identify the cause of the ongoing outbreak.

The UKHSA had previously said there was no evidence linking the outbreak to open farms, drinking water or swimming in contaminated sea, lakes or rivers.

And, while the UKHSA has provided a country-by-country breakdown of cases, we don't know which regions have been worst affected.

We also don't know how bad the outbreak will be. Bacteriologist Prof Nicola Holden said earlier this month: "There is a dependency on the type of source: the epidemiological curves look different for a perishable product compared to something long-lasting, which may be more prolonged."
