UK health authorities say a Salmonella Enteritidis strain linked to 78 illnesses in England and Wales during 2025 and 2026 was also found in a batch of Ukrainian eggs. The affected eggs, from Yasensvit and marked with code 3UA1012066, prompted UK food agencies to tell businesses to stop using them; Ukrainian authorities said they would inspect the company.
UK authorities have linked a Salmonella Enteritidis strain associated with 78 illnesses in 2025 and 2026 to eggs from Ukrainian producer Yasensvit, after testing found the bacteria in a batch of eggs. The UK Food Standards Agency (FSA) and Food Standards Scotland (FSS) asked businesses to stop using eggs marked 3UA1012066 while the investigation continues.
The UK Health Security Agency (UKHSA) reported that the strain was associated with 40 illnesses in England in 2026 and 36 in 2025. Overall, 78 confirmed cases had sample dates between Dec. 17, 2024, and Sept. 26, 2026. Two patients were in Wales; the others lived in England. The reported cases included 32 people in London and 24 in the East of England. Patients ranged in age from under one year to 99, with a median age of 30; 39 were female.
The egg finding came from microbiological testing conducted during a wider investigation into a large Salmonella Enteritidis outbreak involving about 700 patients connected to imported eggs. In October, testing detected the bacteria in three samples, each made up of six pooled eggs, from the Ukrainian producer. Nine bacterial isolates were sent to a reference laboratory. Whole genome sequencing found they were the same strain and that it was associated with human infections, according to the report.
The sampled eggs were reportedly laid and packaged on Aug. 23, 2026, and carried a best-before date of Sept. 19. Sampling took place on Sept. 23, four days after that date. The affected eggs came from Yasensvit, part of Ovostar Union Group. The source report also describes a separate incident: six confirmed patients were linked to a restaurant in Yorkshire and Humber in June 2026, where non-UK eggs were used for some dishes. It does not establish that those restaurant cases were caused by the specific Yasensvit batch.
The Scope of the Egg Alert
The finding matters to businesses that may have received the identified eggs and to people who ate food prepared with them. The FSA and FSS instruction to stop using the marked product gives caterers and other food businesses a specific code to check against their stock. The alert concerns an identified batch; the information provided does not say that all eggs from Ukraine or all Yasensvit products are affected.
Salmonella can cause foodborne illness, and the investigation connects laboratory findings in eggs with a strain associated with infections in people. That link gives public health officials and food businesses a basis for investigating supply chains and potential exposure. However, the information available does not identify how many of the 78 people ate the affected eggs or show that every case arose from this batch. The reported total therefore should not be read as a count of people confirmed to have consumed those eggs.
For consumers, the agency request is directed at businesses, and the source material does not provide a separate consumer recall instruction. The product code and the distinction between an identified batch and a wider product range are relevant to understanding the alert. Anyone seeking current advice should consult UK food-safety authorities, whose guidance may change as investigations progress.

Testing Linked Eggs and Cases
The investigation forms part of work on a wider Salmonella Enteritidis outbreak involving imported eggs. UKHSA testing of nearly 3,000 eggs detected Salmonella in the Ukrainian batch and identified a separate outbreak, according to Food Safety News. Whole genome sequencing compares genetic features of bacterial samples; in this case, the nine isolates were found to match the strain associated with human infections.
The case dates cover nearly two years, from December 2024 through September 2026, while the egg samples were collected in September 2026 and tested in October. The report says Yasensvit had previously urged against drawing what it called “premature conclusions” before all facts were established. Ukraine’s State Service of Ukraine on Food Safety and Consumer Protection said it would inspect the company in Kyiv and take product samples for laboratory testing to verify information received from UK authorities.

Questions About Exposure and Source
The available report does not say how many patients consumed eggs from the identified batch, whether the batch was distributed to consumers, or how many businesses received it. It also does not establish that all 78 illnesses resulted from eating Yasensvit eggs. The broader outbreak linked to imported eggs involved about 700 patients, but the report distinguishes that investigation from the specific finding in the Ukrainian batch.
The Ukrainian inspection and sampling had been announced, but results were not included in the report. It is also unclear whether investigators have traced the eggs’ full distribution, identified any additional affected batches, or issued a consumer-facing recall. The dates on the sampled product and the fact that sampling occurred after its best-before date are reported, but the source does not explain whether that timing affects the investigation’s assessment of the product or the illnesses.
Inspections and Further Food Advice
Ukraine’s food-safety service said it would inspect Yasensvit’s Kyiv operation and collect samples for laboratory analysis. UK agencies may provide further information as they assess the results, trace distribution and determine whether additional action is needed. Businesses should follow the latest directions from the FSA and Food Standards Scotland and check products against the stated code.
The source material does not give a timetable for the Ukrainian inspection findings or a date for further UK updates. It also does not report a broader recall beyond the request that businesses stop using the identified eggs. Any new agency notices would clarify whether the alert changes in scope and what action consumers, suppliers or food businesses should take.
Key Questions
How many illnesses have been linked to the Salmonella strain?
The strain was associated with 78 confirmed cases with sample dates from Dec. 17, 2024, to Sept. 26, 2026: 40 in England in 2026 and 36 in 2025, plus two cases in Wales. The report does not say that all 78 patients ate eggs from the identified batch.
Which eggs did UK agencies ask businesses to stop using?
The affected eggs were from Ukrainian producer Yasensvit and were marked with the code 3UA1012066. The FSA and Food Standards Scotland asked businesses to stop using them.
Does the report say all Ukrainian eggs are affected?
No. The reported finding concerns a specific batch of eggs. The source does not say that all eggs from Ukraine or all products from Yasensvit are affected.
What happens next in Ukraine?
Ukraine’s food-safety service said it would inspect Yasensvit’s operation in Kyiv and take product samples for laboratory testing. The source does not provide a timetable or the results of that inspection.
