GOED omega-3 testing shows 'incredible' quality compliance, but EC hydrocarbon limits will be 'real challenge for sector'

Gerard Bannenberg, GOED’s director of technical outreach and compliance, provided an update on the latest results from GOED’s randomized testing programme during the organisation’s biannual Exchange conference, hosted in Athens, Greece from Jan 22 to 25.

Every year, GOED tests 20 to 24 products via Eurofins labs then reaches out to the owners of the products to provide feedback to improve product quality. The organization provides an overview of the data to member companies, maintaining the confidentiality of the specific products tested.

Omega-3 content

With regard to label claim compliance, the mean of all tested products was 103% of stated EPA/DHA and 106% of total omega-3s. Of all the products tested, 61% contained at least 100% of their claimed EPA/DHA, while 69% contained at least 100% of total claimed omega-3’s.

All products, apart from three “bad” products, provided at least 80% of their label claim which Bannenberg described as “pretty good”.

Looking into oxidation markers, the data did not find any link between oxidative quality indicators and time until end of shelf life, which he suggested “could be interpreted as products having a higher oxidative stability than you might intuitively expect”.


In 2023, the contaminants testing included: heavy metals, dioxins and furands, PCBs, polyaromatic hydrocarbons (PAH; four species), per/polyfluor4oalkyl substances (PFAS; 23 species), bisphenol A, 3-monochloropropanediol (3-MCPD) esters and glycidyl esters, phthalates (plasticizers; 34 species), mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH).
