Danish officials are searching for the source of a Salmonella outbreak that has affected 16 people with one recorded death.
During March and April 2023, 16 cases of Salmonella Muenchen have been recorded.
Eight men and eight women are sick. Patients are aged between 10 and 95 with a median of 73 years old. One person has died and seven have been hospitalized.
Ill people live all over the country with eight cases in Hovedstaden, four in Sjælland, three in Midtjylland, and one in Syddanmark.
The Statens Serum Institut (SSI), Danish Veterinary and Food Administration (Fødevarestyrelsen), and DTU Food Institute are investigating the outbreak.
SSI is continuing to whole genome sequence isolates from patients and interview them or their relatives to try and identify a possible source of infection.
Whole genome sequencing of bacteria isolated from patients has found they were very closely related which suggests that there is a common source of infection.
Salmonella Muenchen is a rare type in Denmark with usually only around two to eight cases per year.
About Salmonella
Food contaminated with Salmonella bacteria does not usually look, smell, or taste spoiled. Anyone can become sick with a Salmonella infection. Infants, children, seniors, and people with weakened immune systems are at higher risk of serious illness because their immune systems are fragile, according to the CDC.
Anyone who has developed symptoms of Salmonella food poisoning should seek medical attention. Sick people should tell their doctors about the possible exposure to Salmonella bacteria because special tests are necessary to diagnose salmonellosis. Salmonella infection symptoms can mimic other illnesses, frequently leading to misdiagnosis.
Symptoms of Salmonella infection can include diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating contaminated food. Otherwise, healthy adults are usually sick for four to seven days. In some cases, however, diarrhea may be so severe that patients require hospitalization.
Older adults, children, pregnant women, and people with weakened immune systems, such as cancer patients, are more likely to develop severe illness and serious, sometimes life-threatening conditions. Some people get infected without getting sick or showing any symptoms. However, they may still spread the infections to others.
