Link to proof of… any of this? I searched around (not just in English language sites) and all I could find was some news reports from November of 2021 that a study was being conducted. Link to the town health orders?
>Only now have measures been taken, as people living within a radius of 15km from Zwijndrecht being advised not to consume eggs laid in their own or anyone’s else’s gardens, whilst pregnant women and children also have to watch out for vegetables from one’s own garden.[0]
This may not be the story the parent poster is referring to but here's an area near me under similar circumstances. As far as I'm aware of, this has happened in other places in the country. I've heard of similar contamination near military bases in Hawaii and also in Okinawa Japan.
Edit: I just realized the question was about a different comment. Leaving this here because I still think it's somewhat relevant and interesting. Apologies.
