New Certificate of Analysis Required for PFAS in Fertilizers

Trade Update • June 24, 2024

he Canada Food Inspection Agency (CFIA) has introduced a new temporary rule concerning per- and polyfluoroalkyl substances (PFAS) in biosolids used as fertilizers. This new regulation, which takes effect on October 18, 2024, requires importers to provide a Certificate of Analysis when bringing these products into Canada, proving they meet the new standards.

Key Details

What are PFAS?

PFAS are a group of man-made chemicals used in various industrial applications and consumer products. They are known for being persistent in the environment and potentially harmful to human and animal health.

What are Biosolids?

Biosolids are nutrient-rich organic materials resulting from the treatment of sewage sludge, commonly used as fertilizer in agriculture.

The New Standard

This standard was developed to address concerns about the potential risks to health and the environment from PFAS contamination in biosolids. Using heavily contaminated biosolids as fertilizer can introduce these harmful substances into the soil, posing risks to crops, animals, and humans. The CFIA’s standard requires that biosolids contain less than 50 ppb (µg/kg) of per-fluorooctane sulfonate (PFOS) as an indicator for PFAS chemicals, in order to be imported or sold in Canada. To import or sell biosolids, a laboratory certificate of analysis showing PFOS testing results and an accompanying attestation will be required.

Detailed guidance: T-4-132: PFAS standard for commercial biosolids imported or sold in Canada as fertilizers.

Background

The new rule came about after extensive consultations with stakeholders and the public during 2023-24. These discussions highlighted the need for stricter controls to protect health and the environment from the risks associated with PFAS in fertilizers.

By implementing this standard, CFIA aims to ensure that fertilizers sold in Canada are safer and less harmful, ultimately benefiting public health and environmental safety.
