Salmonella alert: Bird and cat infections rise in northern Sweden
The Swedish broadcaster SVT reports cases of salmonella in birds and cats in Piteå, heightening the risk of human infection.
The Swedish public broadcaster SVT reported the detection of salmonella in small birds in Piteå, in northern Sweden. In this area, instances of infected cats have also been observed, likely due to their consumption of dead birds. This raises the possibility of bacteria transmission to humans.
Maria Isomursu from the Finnish Food Authority explains that cats can contract salmonella by eating dead birds. Veterinarian Henrik Uhlhorn advises not feeding birds and suggests keeping cats indoors to minimize the risk of infection.
As highlighted by Interia, the occurrence of birds infected with salmonella is not confined to northern Sweden. Isomursu mentions that similar outbreaks happen in Finland, particularly in winter. Affected species include redstarts and greenfinches.
The researcher stresses the importance of caution if a dead bird is found in the yard. Maintaining good hand hygiene after handling a cat or cleaning a litter box is crucial. In cases of numerous dead birds, they should be reported to the Finnish Food Authority.
Salmonella is present in both wild and farm animals. Humans can become infected through food products derived from infected animals or direct contact with infected animals.
Salmonella: Symptoms of the disease
Symptoms typically surface 6 hours to 6 days after infection and generally last 4 to 7 days. In some individuals, particularly children, the elderly, or those with weakened immune systems, the infection can be more severe, leading to dehydration or other complications.
How to prevent salmonella infections:
- Thoroughly cook meat, especially poultry (to an internal temperature of 74°C).
- Avoid consuming raw eggs.
- Wash hands regularly, especially after handling raw meat, eggs, or animals.
- Prevent cross-contamination of food by keeping raw meat separate from ready-to-eat products.
