Key Takeaways
- Swedish health authorities are investigating a listeria outbreak linked to a restaurant in Stockholm.
- Approximately 20 individuals have fallen ill, with several cases of sepsis.
- Contact tracing is underway, with around 400 guests monitored.
- Listeria monocytogenes can survive at refrigerator temperatures, posing a unique threat.
- Diagnosis typically involves clinical symptoms and specific bacteria detection methods.
Helsinki, Oct 3 (NationPress) Swedish health officials have initiated a thorough contact-tracing campaign following a listeria outbreak associated with a restaurant in central Stockholm that has affected approximately 20 individuals, with some progressing to sepsis, as reported by public broadcaster SVT.
According to the Stockholm regional health authority, four patients have developed sepsis, but fortunately, none have required intensive care. Symptoms reported include high fever, diarrhea, and vomiting.
Authorities have reached out to around 400 guests who dined at the restaurant between September 23 and 27 for health monitoring, while there have been at least 80 reports of suspected food poisoning.
Infectious disease expert Viktor Dahl noted that the number of cases is “unusually high,” with a shorter than normal incubation period.
Minister for Social Affairs and Public Health Jakob Forssmed stated that the government has been informed and that “extensive work is being carried out nationwide to track and support patients.”
The restaurant involved, which is currently closed, plans to reopen on October 7, according to Xinhua news agency.
The World Health Organization highlights that foodborne listeriosis is among the most serious foodborne illnesses, caused by the bacteria Listeria monocytogenes. Although it is relatively rare, with 0.1 to 10 cases per 1 million people annually, the significant mortality rate associated with this infection poses a major public health threat.
Unlike many common foodborne pathogens, L. monocytogenes can thrive and reproduce at cold temperatures typically found in refrigerators. Consumption of contaminated food is the primary infection route. The infection can also spread between humans, particularly from pregnant women to their unborn children.
Diagnosis of listeriosis is primarily based on clinical symptoms and the identification of bacteria in samples from blood, cerebrospinal fluid (CSF), newborn meconium (or fetal tissue in abortion cases), as well as from feces, vomit, foods, or animal feed. Various methods, including polymerase chain reaction (PCR), are available for diagnosing listeriosis in humans. During pregnancy, blood and placenta cultures remain the most reliable diagnostic methods for determining if symptoms are attributable to listeriosis.
Point of View
It is imperative to deliver accurate and timely information regarding the recent listeria outbreak in Sweden. The health and safety of the public are paramount, and our reporting aims to provide clarity and facilitate understanding of the ongoing investigation.

Frequently Asked Questions
What is listeriosis?
Listeriosis is a serious infection caused by the bacteria Listeria monocytogenes, which can lead to severe health complications, particularly in vulnerable populations such as pregnant women, newborns, and those with weakened immune systems.
How can listeriosis be transmitted?
Listeriosis is primarily transmitted through the consumption of contaminated food. It can also be spread between humans, notably from pregnant women to their unborn babies.
What are the symptoms of listeriosis?
Common symptoms include high fever, diarrhea, and vomiting. In severe cases, it can lead to sepsis or meningitis.
What measures are being taken to address the outbreak?
Health authorities are conducting extensive contact tracing and monitoring of individuals who dined at the affected restaurant to prevent further cases.
Is listeriosis common?
Listeriosis is relatively rare, with 0.1 to 10 cases per million people annually, but its severe consequences make it a significant public health concern.
