An E.coli outbreak that has made more than 200 people sick has been traced to lettuce – so is it safe to eat?

The Food Standards Agency (FSA) told Sky News it is “too early to determine” how the lettuce leaves may have become contaminated – but it is “confident” that is the source.

Three companies have recalled dozens of sandwiches and wraps sold at supermarkets as a precautionary measure.

So how can lettuce end up carrying E.coli – and does this mean a summer without salad?

How could it happen?

There are three main ways lettuce leaves could have been contaminated with E.coli, according to Professor Jim Monaghan, professor of crop science at Harper Adams University in Shropshire.

E.coli “essentially wants to be inside the guts of warm-blooded animals”, he says, but pathogenic strains can be found in between 10-15% of dairy herds – which means a minority of manure is contaminated with it.

That manure – and the E.coli it carries – can end up on lettuce leaves in cases of direct contamination.

In cases of indirect contamination, the bacteria may get into the soil or water and be transferred to the lettuce that way.

How do farmers prevent contamination?

If farmers use manure to fertilise a field, they have to wait at least a year before they can plant lettuce there.

They must also test the water they are using for irrigation to see if E.coli is present.

“For a lettuce grower, if you’re irrigating a crop with water, if you’re not comfortable drinking that water, then you wouldn’t be irrigating the crop,” Prof Monaghan tells Sky News.

That doesn’t mean they need to irrigate with chlorine-treated tap water, he adds, but it must meet an “acceptable standard”.

Salad growers will also risk assess their sites and avoid planting salad in any areas prone to flooding to avoid potential water contamination.

The FSA has not revealed whether the lettuce came from a UK-based farm or was imported from abroad.

The latest figures show 211 cases of E-coli have been confirmed as of 11 June – and at least 67 people have required hospital treatment.

How does E.coli spread?

Should you be worried about eating lettuce?

Prof Monaghan says he hasn’t changed his lettuce-buying habits in response to the recent outbreak.

“I have a bag of spinach and two whole head lettuces in my fridge at the moment. So knowing what I know about how UK growers manage their risks, to me that’s fine,” he says.

“But clearly something’s gone wrong.”

However, he notes a couple of things – beyond the usual rules growers must follow – that have reassured him about buying salad.

“One is it would appear that the product that’s caused a problem has left the supply chain,” he says.

The second is that everyone involved in salad production – from growers to salad and sandwich manufacturers – will be “sampling like crazy”.

Does washing salad leaves get rid of E.coli?

Once it reaches the factory, lettuce will be rinsed to remove surface contamination. Then chlorine is used to reduce the level of bacteria before it is rinsed again.

That is “effective to a certain extent”, Prof Monaghan says, but it does not eliminate bacteria entirely.

The same goes for washing lettuce at home – it will reduce the amount of bacteria, but not get rid of it.

How does the weather have an impact?

The recent wet weather could have created conditions where E.coli can more easily survive.

On a hot, sunny day, leaves will dry off quickly, reducing the chance of water contamination.

They will also be irradiated by UV rays, killing bacteria.

But on wet, overcast days, there is not the same opportunity for bacteria to be killed off, Prof Monaghan says.

We have had a damp start to the summer – and similar weather has been seen in Spain, Italy and France – all countries that import lettuce to the UK.

Why is it so difficult to trace the root cause?

Darren Whitby, head of incidents at the FSA, said identifying the source of the E.coli was a “complex and ongoing investigation”.

Part of the reason it’s so difficult to trace is because the contaminated products are a very small proportion of the sandwiches on supermarket shelves, Prof Monaghan says.

Then there’s the fact the products in question have a shelf life of days.

“Two days after a sandwich is made, you won’t find that sandwich again,” Prof Monaghan says.

“It’s either been eaten or it’s been taken off the shelf.”

The FSA has been investigating the issue along with the UK Health Security Agency (UKHSA), Food Standards Scotland and devolved public health agencies, businesses and local authorities.

Through epidemiological investigations and whole genome sequence analysis, they narrowed down the common foods consumed by people who had fallen ill to a small number of salad leaf products used in sandwiches, wraps, subs and rolls.

Dozens of products were recalled; while no E.coli had been found in them, it was a “precautionary measure” in case they were contaminated.

The fact E.coli was not found in the products indicates it has left the supply chain. “There’s no smoking gun,” Prof Monaghan says.

At least 13 people may have taken their own lives linked to Post Office scandal, public inquiry finds

At least 13 people may have taken their own lives linked to Post Office scandal, public inquiry finds

At least 13 people may have taken their own lives after being accused of wrongdoing based on evidence from the Horizon IT system that the Post Office and developers Fujitsu knew could be false, the public inquiry has found.

A further 59 people told the inquiry they considered ending their lives, 10 of whom tried on at least one occasion, while other postmasters and family members recount suffering from alcoholism and mental health disorders including anorexia and depression, family breakup, divorce, bankruptcy and personal abuse.

Follow latest on public inquiry into Post Office scandal

Writing in the first volume of the Post Office Horizon IT Inquiry report, chairman Sir Wyn Williams concludes that this enormous personal toll came despite senior employees at the Post Office knowing the Horizon IT system could produce accounts “which were illusory rather than real” even before it was rolled out to branches.

Sir Wyn said: “I am satisfied from the evidence that I have heard that a number of senior, and not so senior, employees of the Post Office knew or, at the very least, should have known that Legacy Horizon was capable of error… Yet, for all practical purposes, throughout the lifetime of Legacy Horizon, the Post Office maintained the fiction that its data was always accurate.”

Referring to the updated version of Horizon, known as Horizon Online, which also had “bugs errors and defects” that could create illusory accounts, he said: “I am satisfied that a number of employees of Fujitsu and the Post Office knew that this was so.”

The first volume of the report focuses on what Sir Wyn calls the “disastrous” impact of false accusations made against at least 1,000 postmasters, and the various redress schemes the Post Office and government has established since miscarriages of justice were identified and proven.

‘It stole a lot from me’

Recommendations regarding the conduct of senior management of the Post Office, Fujitsu and ministers will come in a subsequent report, but Sir Wyn is clear that unjust and flawed prosecutions were knowingly pursued.

“All of these people are properly to be regarded as victims of wholly unacceptable behaviour perpetrated by a number of individuals employed by and/or associated with the Post Office and Fujitsu from time to time and by the Post Office and Fujitsu as institutions,” he says.

What are the inquiry’s recommendations?

Calling for urgent action from government and the Post Office to ensure “full and fair compensation”, he makes 19 recommendations including:

• Government and the Post Office to agree a definition of “full and fair” compensation to be used when agreeing payouts
• Ending “unnecessarily adversarial attitude” to initial offers that have depressed the value of payouts, ⁠and ensuring consistency across all four compensation schemes
• The creation of a standing body to administer financial redress to people wronged by public bodies
• Compensation to be extended to close family members of those affected who have suffered “serious negative consequences”
• The Post Office, Fujitsu and government agreeing a programme for “restorative justice”, a process that brings together those that have suffered harm with those that have caused it

Regarding the human impact of the Post Office’s pursuit of postmasters, including its use of unique powers of prosecution, Sir Wyn writes: “I do not think it is easy to exaggerate the trauma which persons are likely to suffer when they are the subject of criminal investigation, prosecution, conviction and sentence.”

He says that even the process of being interviewed under caution by Post Office investigators “will have been troubling at best and harrowing at worst”.

‘Hostile and abusive behaviour’

The report finds that those wrongfully convicted were “subject to hostile and abusive behaviour” in their local communities, felt shame and embarrassment, with some feeling forced to move.

Detailing the impact on close family members of those prosecuted, Sir Wyn writes: “Wives, husbands, children and parents endured very significant suffering in the form of distress, worry and disruption to home life, in employment and education.

“In a number of cases, relationships with spouses broke down and ended in divorce or separation.

“In the most egregious cases, family members themselves suffered psychiatric illnesses or psychological problems and very significant financial losses… their suffering has been acute.”

The report includes 17 case studies of those affected by the scandal including some who have never spoken publicly before. They include Millie Castleton, daughter of Lee Castleton, one of the first postmasters prosecuted.

Three things you need to know about Post Office report

She told the inquiry how her family being “branded thieves and liars” affected her mental health, and contributed to a diagnosis of anorexia that forced her to drop out of university.

Her account concludes: “Even now as I go into my career, I still find it so incredibly hard to trust anyone, even subconsciously. I sabotage myself by not asking for help with anything.

“I’m trying hard to break this cycle but I’m 26 and am very conscious that I may never be able to fully commit to natural trust. But my family is still fighting. I’m still fighting, as are many hundreds involved in the Post Office trial.”

Business Secretary Jonathan Reynolds said the inquiry’s report “marks an important milestone for sub-postmasters and their families”.

He added that he was “committed to ensuring wronged sub-postmasters are given full, fair, and prompt redress”.

“The recommendations contained in Sir Wyn’s report require careful reflection, including on further action to complete the redress schemes,” Mr Reynolds said.

“Government will promptly respond to the recommendations in full in parliament.”

Post Office scandal inquiry lays bare a second injustice

The long-awaited first report from the Post Office Horizon scandal inquiry lays bare not just the devastating personal toll of one of the greatest miscarriages of justice in British legal history, but also the slow-motion failure of the government and the Post Office to deliver meaningful redress.

Sir Wyn Williams’s first report documents with stark clarity how hundreds of sub-postmasters, wrongly accused of theft and fraud due to the faulty Horizon IT system, lost their livelihoods, homes, reputations – and in some cases, their lives.

Thirteen people are believed to have taken their lives as a result of the scandal.

Fifty-nine contemplated it.

It talks of alcohol addiction, serious mental illness, and bankruptcy – all tearing families apart and leaving behind a heartbreaking legacy.

But if the scandal was a failure of justice, the response to it has become a second injustice.

Critical on a technical level

The report is critical, on a fairly technical level, about the complexity, delays, and bureaucracy of redress schemes that have left victims still waiting years for full compensation.

‘It stole a lot from me’

Hundreds of whom have died before seeing “full and fair redress”.

While Sir Wyn is fair to the government and the Post Office in stating that he believes their commitment to delivering the above has been in “good faith”, he concludes this has not been achieved for every victim, describing “formidable” difficulties.

There are 19 recommendations – including a push to ensure consistency across all four redress schemes, with an agreed and public definition of “full and fair redress”.

Compensation

Among them, that family members of victims should be compensated, and a permanent public body established to manage future redress schemes in future.

Additionally, Fujitsu, the Post Office, and the government should engage in formal restorative justice programmes.

There was also a flavour of what is to come in the final report later this year or next.

The report has found that both Fujitsu and Post Office staff knew Horizon could produce false data but concealed this, maintaining a false narrative of accuracy.

One of the most important things now, though, is how and when the government, Post Office, and Fujitsu respond officially.

Sir Wyn has also set a deadline of 10 October 2025 for that.

The victims of this scandal have waited long enough.

‘Wholesale failure’ to address risks posed by Southport attacker before murders, says public inquiry chairman

'Wholesale failure' to address risks posed by Southport attacker before murders, says public inquiry chairman

There was a “wholesale and general failure” to address the risks posed by Axel Rudakubana before the Southport attack, the chairman of the public inquiry into the murders has said.

In his opening statement at Liverpool Town Hall, Sir Adrian Fulford said the teenager’s “known predilection for knife crime” suggests it was “far from an unforeseeable catastrophic event”.

The former vice president of the Court of Appeal said Rudakubana’s actions “impose the heaviest of burdens” to investigate how it was possible for him to cause “such devastation”.

‘We need to understand what went wrong’

The 18-year-old murdered Elsie Dot Stancomb, seven, Bebe King, six, and Alice da Silva Aguiar, nine, at a Taylor Swift-themed class on 29 July last year.

He also injured eight other children and two adults at the Hart Space in the Merseyside seaside town, with Sir Adrian describing the attack as “one of the most egregious crimes in our country’s history”.

‘We don’t want Elsie forgotten’

The public inquiry, announced by Home Secretary Yvette Cooper in January, will look into whether the attack could or should have been prevented, given what was known about the killer.

Rudakubana, who was born in Cardiff, had been referred to the government’s anti-extremism Prevent scheme three times before the murders, including over research into school shootings and the London Bridge terror attack.

He had also accessed online material about explosives, warfare, knives, assassination and an al Qaeda training manual.

A rapid review into his contact with Prevent found his case should have been kept open and that he should have been referred to Channel, another anti-terror scheme.

What is the anti-terrorism programme Prevent?

Rudakubana was twice caught with a knife and managed to hoard other blades, as well as a bow and arrow, machetes, a sledgehammer and the deadly toxin ricin at his home.

He bought the 20cm chef’s knife used to carry out the attack using a Virtual Private Network (VPN).

Sir Adrian said he did not want to pre-judge the outcome of the inquiry.

But he added: “These factors, if correct and when taken together, tend to suggest that far from being an unforeseeable catastrophic event, the perpetrator posed a very serious and significant risk of violent harm, over a number of years, with a particular and known predilection for knife crime.

“Furthermore, his ability, unhindered, to access gravely violent material on the internet, to order knives online when underage, and then to leave home unsupervised to commit the present attack, speaks to a wholesale and general failure to intervene effectively, or indeed at all, to address the risks that he posed.”

Sir Adrian said the inquiry will examine decisions taken in light of Rudakubana’s “deteriorating and deeply troubling behaviour” to identify “without fear or favour” all of the relevant failings.

He said he aims to make recommendations to ensure the best chance of stopping others “who may be drawn to treating their fellow human beings in such a cruel and inhuman way”.

Rudakubana, 18, was jailed for a minimum of 52 years in January and is being investigated over an alleged attack on a prison officer at Belmarsh prison in May.

Sir Adrian said he would be referred to by his initials or as “the perpetrator” during the inquiry and asked the media not to show his “terrifying and singularly distressing” police mugshot to avoid causing distress to the survivors and their families, who have been granted anonymity.

The surviving children, many whom were under the age of 10, are “bravely trying to cope with school life in the face of what they have suffered,” he added.

Sir Adrian asked those in the room to stand for a minute’s silence for the victims.

Some of those whose children were injured will speak at a hearing on Wednesday before the inquiry is adjourned to 8 September, with the first phase expected to last until November.

It will then move on to a second phase next year to “consider the wider issues of children and young people being drawn into extreme violence”.

Rachael Wong, director at law firm Bond Turner, representing the three bereaved families, said: “We know that nothing the inquiry reveals or subsequently recommends will change the unimaginable loss felt by the families of Elsie, Alice and Bebe, but we all now have a responsibility to ensure that something like this never happens again.

“We will be doing all we can to assist the chair through the inquiry and uncover the truth.

“It is only through intense public scrutiny that real change can be effected.”

Sefton Council is asking people not to leave flowers near schools or the scene of the attack to mark the anniversary later this month, but to donate to local charitable causes instead.

There will be a three-minute silence and flags will be lowered to half-mast on public buildings around the Liverpool city region.

“We fully understand that many of us still need to grieve and to mark the day,” the council said in an open letter.

“Our colleagues have been working with faith and community leaders to identify local spaces where you can go, within your neighbourhood, to pay tribute, whether this be to say a prayer, light a candle, speak to someone or quietly reflect in a way that feels right for you.”
