The County Administrative Board of Östergötland conducted an unannounced inspection of Kolmården's dolphinarium in November 2025, according to official records. The inspection was triggered by an anonymous complaint regarding the keeping of the dolphins, which alleged health problems in the dolphins linked to water quality, including high chlorine levels causing rashes, affecting breathing, and recurring eye problems.
The County Administrative Board found deficiencies that need to be corrected, as confirmed in their inspection report. However, Kolmården does not want to specify what the deficiencies involve, and the inspection report is classified as confidential due to internal business and operational matters, leaving the exact nature and timeline of the corrective measures required from the zoo unclear.
The dolphins are doing well and are cared for by our animal keepers who know the individuals well and have extensive knowledge of the species. Our animal health team, such as veterinarians and zoologists, are available for further assessment if needed.
In a written comment, Kolmården states that it welcomes the inspection and takes the feedback very seriously. The zoo also states that the dialogue with the County Administrative Board concerns various alternatives for a long-term plan for the dolphins and the dolphinarium's management. Kolmården emphasizes that the dolphins are doing well and are cared for by animal keepers who know the individuals well and have extensive knowledge of the species.
The anonymous complaint also criticizes the condition of the pools, alleging leaks and limescale deposits that can promote bacterial growth. According to Aftonbladet, the inspection was conducted in November last year based on information that the dolphins could have health problems linked to water quality.
Kolmården announces that the remaining dolphins continue to perform. According to Aftonbladet, the zoo now has the opportunity to address the deficiencies, as part of ongoing efforts to comply with regulatory requirements and ensure animal welfare standards.
