An unannounced inspection at Kolmården's Dolphinarium took place in November 2025, prompted by reports indicating potential health problems for the dolphins linked to the water quality in their habitat. The inspection, conducted by the Swedish County Administrative Board, uncovered deficiencies that must be addressed to ensure the welfare of the animals. The county administration emphasized the importance of the public complaint that triggered this oversight, highlighting that animal welfare standards are a significant concern.

Kolmården Zoo has been given the opportunity to rectify the identified shortcomings, and a follow-up inspection will be conducted to monitor the zoo's compliance with animal care standards. Kristoffer Hellberg, a department head at the County Administrative Board, noted the seriousness of the findings but refrained from detailing the specific issues uncovered during the inspection. The zoo has publicly acknowledged receipt of the County Board's report and expressed a commitment to addressing their recommendations carefully.

In response to the situation, Kolmården has opted not to provide a recorded interview but stated through written communication that they take the feedback from the County Board seriously. The zoo's management stressed the importance of reviewing the findings thoroughly, aiming to ensure high standards of animal welfare. This incident raises critical questions about the management of marine mammals in captivity and their environmental conditions, shining a spotlight on regulatory practices in Swedish animal care facilities.
