A silent chemical threat is spreading across our planet. PFAS levels are rising in food, water, food contact materials, and even human bloodstreams.

Chemical structure, persistence, and health impacts.
PFAS are a large family of fluorinated organic compounds used in coatings, surfactants, and polymers.
Chemical Structure
Synthetic compounds with strong carbon–fluorine (C–F) bonds,
making them highly stable and resistant to degradation.
Persistence
Do not readily break down in the environment ("forever chemicals").
Bioaccumulation
Can accumulate in living organisms over time.
Mobility
Water-soluble forms travel easily through soil and water, spreading
contamination.
Toxicological Relevance
Possible risks to health include immune, hormonal,
developmental, and carcinogenic disease.
Frequently detected in surface water, groundwater, and drinking water due to industrial discharges, firefighting foams, wastewater effluents, and landfill leachates.
Bioaccumulation in the food chain
Fish, seafood, meat, and eggs from contaminated environments.
Agricultural pathways
Crops irrigated with PFAS-contaminated water or grown in contaminated soil.
Food contact materials
Migration from PFAS-treated packaging, cookware, or processing equipment.
Regulatory limits and standards across key regions.
The WHO has advised a guidance level of PFAS in drinking water at 0.5 µg/L for PFAS Total and 0.1 µg/L for PFOS and PFOA.
Finalized in April 2024, enforcing limits for PFOA at 4 ng/L, PFOS at 4 ng/L, PFNA at 10 ng/L, PFHxS at 10 ng/L, HFPO-DA at 10 ng/L, and a Hazard Index for mixtures including PFBS. Some timelines are under review, but limits for PFOA and PFOS remain.
Effective 12 January 2026, mandating PFAS Total at 0.5 µg/L and for the sum of 20 specific PFAS at 0.1 µg/L.
To take effect by April 2026, for a sum of PFOS and PFOA at 0.00005 mg/L. The same limits are applicable to bottled water.
Provides the recommended limits for PFOS at 0.08 µg/L and PFOA at 0.04 µg/L.
Established provisional thresholds in drinking water for PFOS at 0.07 µg/L, PFOA at 0.07 µg/L, and PFHxS at 0.48 µg/L with ongoing tightening and wider control lists.
Proposed stricter guidance in the draft of NHMRC's review at 0.2 µg/L for PFOA, 4 ng/L for PFOS, 0.03 µg/L for PFHxS, 1.0 µg/L for PFBS, and 0.01 µg/L for HFPO-DA.
Maximum levels (MLs) for PFAS in defined foods such as fishery products, meat, eggs, and offal, with consolidated updates announced in 2025. MLs differ between matrices.
Does not have any federal MLs for PFAS in foods. The FDA conducts regular market surveys and manages authorized uses in food contact.
Has not set any MLs for PFAS in foods. Central authorities are focusing on the market investigation of PFAS contamination in food.
Has not yet established any mandatory MLs for PFAS in food.
Has limited food MLs while it is expanding its monitoring efforts.
Does not currently see the need for MLs as Food Standards Australia New Zealand (FSANZ) notes very low PFAS levels in the general food supply, however, monitoring continues.
REACH is advancing. The EU Packaging and Packaging Waste Regulation (PPWR) will introduce PFAS limits in food contact packaging in August 2026 at 25 µg/L for individual PFAS and 250 µg/L for total PFAS.
Has enforced a ban on PFAS in paper and board food contact materials unless a proven functional barrier is present, effective since July 2020.
Enforced a 'positive list' that defines the compounds that are allowed to be used as food contact polymers and additives. PFAS-related entries should be tracked via notices issued by MHLW.
Revised standards for utensils, containers, and packages. Under discussion about regulation of PFAS use.
Specified that national controls on specific PFAS now apply under chemical management law, and packaging assessments should reflect those restrictions.
FDA has ended authorized uses for grease proofing PFAS on paper and paperboard. Packaging suppliers moved away from such uses in 2024.
