100% of animals (only 8, because of limited funding for testing) tested in 2020 by the Southern Hunter's Circle in Gävle (that embedded link in my post) in were over 1500 Bq/kg, with an average of 6263 Bq/kg.
SSI/Livsmedelsverkets's irradiation limits are "low" (your opinion) for a reason, because we just don't really know much about the long-term effects. These limits have not been changed since 1986 in Sweden, but what I do know is that they're 3 times higher than, for instance, in Germany, which sets the limit at 600 Bq/kg. The US: 370 Bq/kg. Japan (implemented in 2012 after the Fukushima incident, because there were no prior legal binding limits): 100 Bq/kg. Yeah, what a "pity", as you say.
The original post was not "preposterous".
