As of 1.1.2023, maximum levels for PFAS in certain foodstuffs of animal origin will apply. AGROLAB LUFA GmbH has expanded its range of tests to include the accredited determination of perfluorinated and polyfluorinated alkyl substances.

 

In EU Regulation 2022/2388 of Dec. 7, 2022, binding limits are set for the four most important representatives of PFAS for certain foods of animal origin. These are the following compounds:



Regulated perfluoro alkyl substances

PFOS

Perfluorooctane sulfonic acid

PFOA

Perfluorooctanoic acid

PFNA

Perfluorononanoic acid

PFHxS

Perfluorohexanesulfonic acid

 

These substances are examples of thousands of perfluorinated and polyfluorinated alkyl substances that have been used in many industrial applications for decades and whose residues are now distributed ubiquitously in the environment. All compounds have in common that they are difficult to biodegrade and are therefore described as persistent. They enter our food through bioaccumulation within food chains, but also through packaging and contact materials.

 

It has now been scientifically proven that accumulation of the compounds in the human and animal organism can also lead to adverse health effects. Liver diseases and negative influences on the immune system are particularly critical. Especially in young children, exposure can lead to the weekly tolerable intake (TWI) of 4.4 ng/kg body weight being exceeded.

 

On this basis, the EU Commission derived the following maximum permissible levels, which were added to the Annex of Regulation (EC) No. 1881/2006 (Contaminants Regulation):

All figures in µg/kg fresh weight

 

* The maximum level applies to the sum of linear and branched stereoisomers, whether they are chromatographically separated or not.
** For the sum of PFOS, PFOA, PFNA and PFHxS, lower bound concentrations are calculated on the assumption that all the values below the limit of quantification are zero.

For an explanation of the footnotes, please refer to the text of the regulation.

 

Important: For the analysis and subsequent correct evaluation of results, it is essential that a correct species declaration is available for fish meat and that the intended use of the goods is known.

 

YOUR PLUS: Our LC MS/MS method is accredited for all mentioned matrices. The limit of quantification is 0.1 µg/kg for the regulated compounds, enabling legally compliant evaluation. In addition, we are also accredited to test fish oils for PFAS with a limit of quantification of 0.25 µg/kg.
