In St. Gallen, five farms are banned from selling meat due to excessive PFAS contamination. Environmental chemist Martin Scheringer discusses the prevalence of these ‘forever chemicals’ in daily life, including their presence in drinking water, food, and outdoor gear. While PFAS can lead to serious health issues, including cancer, their effects take time to manifest. Scheringer emphasizes the need for improved measurement and regulation of PFAS to protect public health.
