Sweden reported 16 people sickened in a Salmonella Napoli outbreak suspected to be linked to arugula traced to Italy. Investigators connected purchases by 11 patients to the same supermarket chain, but the implicated batch was not available for sampling, and the source has not been confirmed.
Sixteen people in Sweden were sickened in a Salmonella Napoli outbreak suspected of being linked to arugula from Italy, according to the Public Health Agency of Sweden. Investigators traced a package from one patient’s home to Italy, but the suspected batch was no longer available for testing, so the source has not been confirmed.
The patients were eight men and eight women, ranging in age from under 1 to 84, with a median age of 57, the agency said. Reported illness onsets ran from August 17 through September 6. Officials noted a couple of later-onset cases that might have been secondary infections or involved people without gastrointestinal symptoms.
Twelve patients were interviewed or responded to questionnaires about their food purchases. Eleven said they had bought arugula from the same supermarket chain; the remaining respondent had bought a salad mix containing arugula from that chain. The purchases took place within a relatively short period, according to the report.
One patient kept the empty arugula package at home before placing it in plastic recycling. The Swedish Food Agency used information from that packaging in a trace-back investigation, which led to Italy. No product remained from the batch, however, so investigators could not sample it. The available information supports a suspected link, not laboratory confirmation that the arugula caused the illnesses.
Why the Arugula Lead Matters
The investigation shows how purchase histories and packaging can help public health authorities follow a food lead even after the product has been eaten or discarded. In this case, an empty package helped trace the supply chain to Italy, while interviews identified a shared supermarket chain among most of the people questioned.
But the missing batch limits what investigators can establish. Without a sample from the product, the report does not confirm that it carried Salmonella or identify a particular producer, shipment, or point of contamination. For readers, the distinction matters: the suspected food is arugula, but no specific product has been confirmed as the cause in the supplied report.
The agency said Salmonella Napoli is uncommon in Sweden: eight cases were reported in 2025. That figure provides recent national context, but the report does not give a comparison period or data to show how the current outbreak changes the longer-term trend.

How Investigators Traced the Salad
The outbreak investigation combined patient interviews and questionnaires with food traceability work. The shared purchases raised suspicion around arugula sold through one supermarket chain, including arugula bought on its own and as an ingredient in a salad mix. Those accounts are relevant clues, but they do not by themselves prove that all patients ate the same product or that the product was contaminated.
The package retained by one patient offered a route to identify the product’s origin. The Swedish Food Agency traced it to Italy, but the batch was gone before sampling could take place. The report does not provide a brand, supplier, distribution dates, or details of any recall linked to the outbreak.
The report also mentioned a separate food-safety event in Uppsala, where home-delivered meals resumed after a Listeria finding. Officials said testing limited contamination to seven containers of bean stew and that other kitchen and dish samples showed no Listeria. That incident is separate from the Salmonella outbreak and does not establish a connection between the two events.
“Salmonella Napoli is not a very common serotype in Sweden, with only eight reported cases in 2025.”

What Testing Could Not Establish
The source of the outbreak remains suspected, not confirmed. Although patient reports and the trace-back point toward arugula associated with Italy, no sample from the identified batch was available to test. The report does not say whether investigators found Salmonella in another related product or whether they identified a specific farm, processor, or shipment.
It is also not clear from the report whether additional cases have been detected since the stated onset period, whether the investigation is still active, or whether authorities issued a product warning or recall. The later-onset cases were described as potentially secondary or as involving people without gastrointestinal symptoms; the report does not provide further detail on how those cases were classified.
Further Case and Traceback Updates
The report does not give a timetable for further updates or describe a next testing milestone. Any later findings from the Swedish public health or food-safety authorities could clarify whether the suspected arugula link is supported by additional traceability or laboratory evidence, and whether a particular product or supplier can be identified.
For now, the confirmed information is limited to the reported cases, patient purchase histories, and the trace-back of one package to Italy. Readers should distinguish those findings from a confirmed identification of contaminated food; the source material does not name a specific brand or report a recall connected to the Salmonella cases.
Key Questions
How many people were sickened in the Swedish outbreak?
Sixteen people were reported sick with Salmonella Napoli, according to the Public Health Agency of Sweden.
What food is suspected of being linked to the cases?
Investigators suspect arugula, including arugula in a salad mix. Most of the patients interviewed or surveyed reported buying arugula from the same supermarket chain. The link has not been confirmed by testing the suspected batch.
Was the arugula traced to Italy tested?
No. A package kept by one patient helped trace the product to Italy, but no arugula from that batch remained for sampling.
When did the reported illnesses begin?
The reported onset dates ranged from August 17 to September 6. The report also mentions a couple of later-onset cases that might have been secondary cases or people without gastrointestinal symptoms.
Has a specific brand or recall been identified?
The supplied report does not identify a brand, producer, or Salmonella-related recall. It says the source is suspected and that the implicated batch was unavailable for testing.
