The US Food and Drug Administration (FDA) has rejected a petition to set limits on toxic PFAS 'forever chemicals' in food, despite growing evidence of their health risks. PFAS have been linked to cancer, birth defects, and other serious health problems, and are commonly used in pesticides, food packaging, and sewage sludge used as fertilizer. The FDA plans to set non-binding 'action levels' instead of enforceable limits, which has been met with criticism from public health advocates. The decision has sparked concerns about the safety of the food supply and the effectiveness of regulatory agencies in protecting public health.
