According to a press release from the Zug authorities, eating fish contaminated with PFAS does not pose an acute health risk. However, repeated ingestion of the chemicals over the years can cause chronic damage to health and should therefore be avoided.

Financial support planned
The ban will mean financial losses for professional fishermen and women. The cantonal government is “in principle” in favour of providing support and has commissioned the Office for Forests and Wildlife (AFW) to clarify the details.
The office will also be responsible for the disposal of pike and perch caught by professional anglers in future. Recreational anglers will be provided with containers at the municipal carcass collection centres.
“All fish caught must continue to be recorded in the catch statistics and reported to the AFW,” according to a press statement.

Pfas entries are being investigated
Whitefish were also analysed but their FPAS contamination did not exceed the maximum values. Fish from Lake Aegeri in canton Zug and from fish farms are also not affected by the ban.
The samples were part of a one-year monitoring programme. This started after random samples from the second half of 2024 indicated that the PFAS maximum levels may have been exceeded.
The PFAS chemicals in Lake Zug originate mainly from contaminated sites such as former fire training and fire event sites and former factory zones. Current PFAS inputs are being investigated, according to the press release. There are indications that these were higher in the past than they are today.
