UK authorities report 78 confirmed Salmonella Enteritidis cases in England and Wales from December 2024 to September 2026 associated with a strain found in eggs from Ukrainian producer Yasensvit. The Food Standards Agency and Food Standards Scotland asked businesses to stop using eggs bearing code 3UA1012066; Ukrainian authorities said they would inspect the company and test samples.
UK health authorities have linked 78 confirmed Salmonella Enteritidis cases recorded between December 2024 and September 2026 to a strain detected in eggs from Ukrainian producer Yasensvit. The Food Standards Agency and Food Standards Scotland asked businesses to stop using eggs bearing the stamp 3UA1012066, while Ukraine’s food-safety authority said it would inspect the company and take samples for testing.
The cases were reported in England and Wales: 76 people lived in England and two in Wales. The UK Health Security Agency said the case samples date from Dec. 17, 2024, through Sept. 26, 2026. Of the cases, 32 were in London and 24 in the East of England. Patients ranged in age from younger than 1 to 99, with a median age of 30; 39 were female.
In October, testing found Salmonella Enteritidis in three pooled samples, each made up of six eggs from the Ukrainian producer. Nine bacterial isolates were sent to a reference laboratory. Whole genome sequencing found the isolates were the same strain and associated with human infections, according to the report. The eggs were sampled on Sept. 23, 2026. They were reportedly laid and packed on Aug. 23, with a best-before date of Sept. 19.
The UK investigation also includes a broader Salmonella Enteritidis outbreak involving 700 patients linked to imported eggs. Nearly 3,000 eggs were tested as part of that investigation. A separate cluster involved six confirmed patients in June 2026, linked to a restaurant in Yorkshire and the Humber that used non-UK eggs for certain dishes. The source report does not say that this restaurant cluster was caused by the Yasensvit eggs.
Businesses Told to Remove Marked Eggs
The warning gives food businesses a specific product code to check and directs them to stop using the affected eggs. Salmonella can cause illness, making the link relevant to businesses handling eggs and to customers who may have eaten food prepared with them. The reported illnesses span nearly two years, but the source material does not establish how many cases resulted from any one batch or whether the marked eggs remain in circulation.
The case count and genetic match also matter for public-health surveillance. Whole genome sequencing can identify whether bacteria from separate samples are closely related. Here, UK authorities reported that the isolates matched the strain associated with human infections. That finding supports the stated link, but does not by itself identify the route of contamination or establish that every case had direct contact with the named eggs.

How Testing Connected the Cases
The investigation sits within a larger UK response to Salmonella Enteritidis cases associated with imported eggs. As part of the work, the UK Health Security Agency tested nearly 3,000 eggs. In October, testing identified the bacteria in three pooled samples from Yasensvit; laboratory sequencing then connected the isolates with a strain associated with illnesses.
Yasensvit is part of Ovostar Union Group, which the source report describes as a major European egg and egg-product producer operating in international markets. The company had previously urged people not to draw what it called “premature conclusions” before all facts were established. The report does not provide a new company response to the latest findings.
Ukraine’s State Service of Ukraine on Food Safety and Consumer Protection said it would conduct an inspection at the company in Kyiv and collect product samples for laboratory testing, following information from UK authorities. The planned inspection is a separate national follow-up to the UK investigation.
““premature conclusions””

Questions About Scope and Exposure
The reported evidence connects a bacterial strain found in sampled Yasensvit eggs with human infections, but the source does not specify how many of the 78 cases were linked to the identified batch, or whether the eggs were distributed to consumers. It also does not report the outcome of the planned Ukrainian inspection or testing.
The sampling details raise a timing question: the eggs were reportedly sampled on Sept. 23, four days after their Sept. 19 best-before date. The source does not explain why the samples were collected then, how they had been stored, or whether that timing affected the test results. It also does not give a complete breakdown of illnesses by year beyond reporting 40 associated cases in England in 2026 and 36 in 2025; those figures do not account for all 78 cases across the full date range.
The report does not state whether additional product recalls or consumer warnings were issued, nor does it provide a current estimate of the risk to the public. The broader 700-patient outbreak and the six-person restaurant cluster are described separately, and the available information does not establish that either was caused by the specific Yasensvit batch.
Inspection and Follow-Up Testing
Ukraine’s food-safety authority said it would inspect Yasensvit’s Kyiv operation and test product samples. The results could clarify whether the company’s products or facilities show evidence relevant to the UK findings. UK authorities may also continue investigating the cases and tracing the distribution of eggs carrying stamp 3UA1012066; the source material does not give a timetable for either process.
Businesses should follow instructions from the Food Standards Agency and Food Standards Scotland to stop using the marked eggs. Further information from UK or Ukrainian authorities, including inspection findings, product-distribution details, or updated case counts, would help clarify the scale and status of the link.
Key Questions
How many illnesses have UK authorities linked to the eggs?
The report gives 78 confirmed cases in England and Wales, with case sample dates from Dec. 17, 2024, to Sept. 26, 2026. It also reports 40 associated cases in England in 2026 and 36 in 2025.
Which eggs did authorities identify?
The eggs were from Ukrainian producer Yasensvit and bear the stamp 3UA1012066. The Food Standards Agency and Food Standards Scotland asked businesses to stop using them.
How did investigators connect the eggs to illnesses?
Testing detected Salmonella Enteritidis in three pooled egg samples. Whole genome sequencing found that nine isolates were the same strain and associated with human infections, according to the UK investigation.
Has Ukraine completed its inspection?
The source report says Ukraine’s food-safety authority planned an inspection in Kyiv and product sampling for laboratory testing. It does not report the inspection’s outcome.
Is the separate restaurant outbreak confirmed to involve Yasensvit eggs?
No such connection is established in the source material. It reports six cases linked to a Yorkshire and the Humber restaurant that used non-UK eggs, but does not say those eggs came from Yasensvit.
