Salmonellosis in Sweden

5 July, 2021

Salmonella was not detected in any of the 4147 broiler flocks tested in routine sampling before slaughter. Salmonella was detected in 7 of the 646 flocks of layers tested. Salmonella was not detected in any breeding flocks, neither in any samples of commercially raised turkey flocks, quails, or ostriches. Salmonella was detected in one small-scale flock with laying hens, ducks and geese.  It is estimated that approximately 20% of the poultry holdings lackan annual official sampling.Humans: In 2020, a total of 826 cases of salmonellosis were reported, compared to 1993 cases in 2019. Domestic cases decreased by 45% from 763 cases in 2019 to 422 cases in 2020, resulting in an incidence of 4.1 cases per 100 000 inhabitants. The low proportion of domestic Salmonella infections in humans is unique to Sweden, Norway and Finland when compared to most other European countries, where such data is collected. This reflects the low Salmonella burden in domestic animals and food.
