Abstract
Enteritidis (SE) cases in humans have increased in the Netherlands, from an annual average of 281 (2017-2019) to 427 in 2023, 401 in 2024 and 209 in 2025 (January-June). This rise is paralleled by a 2.5-fold increase in SE-positive laying hen flocks. Genomic surveillance shows numerous small clusters, suggesting a diffuse transmission rather than a single point-source outbreak, which complicates outbreak investigations. Coordinated interventions in the laying hen sector are urgently needed to mitigate public health risks.
