PFAS represent one of the major contemporary challenges for regulatory toxicology. Their persistence, environmental mobility and possible presence in formulations, materials or industrial processes require assessment tools capable of detecting sources that are not always evident.
In the veterinary and agro-livestock sectors, the issue does not concern only substances declared as active ingredients. It may involve co-formulants, packaging materials, treated surfaces, production processes and secondary contamination dynamics.
A modern risk assessment should therefore connect analytical chemistry, environmental fate, animal exposure, food safety and public health. Within this framework, veterinary pharmacology and toxicology can help identify exposure scenarios that remain underestimated.
The regulatory frontier is not only to prohibit or authorise, but to build surveillance, traceability and prevention systems capable of recognising emerging contaminants at an early stage.
