The PFAS are also in the ketchup: shock survey detects the worst and best brands, the US ranking

PFAS are everywhere, even in ketchup. A certified testing laboratory found detectable quantities in 65% of cases

Don't store avocado like this: it's dangerous

PFAS are everywhere, even in ketchup. Mamavation sent 12 samples of the common seasoning to a certified testing laboratory, which found detectable quantities in 65% of cases, possibly due to manufacturing contamination of Teflon or other chemicals.

PFAS is the acronym for Perfluoroalkyl substances and actually refers to a family of synthetic organic compounds all made up of an alkyl chain (i.e. of –CH in different proportions), linear or branched, generally from 4 to 16 carbon units , totally or partially fluorinated: in the first case we speak of "perfluorinated" substances, in the second of "polyfluorinated".

And they are now everywhere, in many everyday objects but also in rainwater, in the oceans and in the dust of our homes, in paints, food packaging, household products up to cosmetics. They are also found in the top layer of solar panels, artificial grass and fire fighting foams.

Their enormous diffusion has caused the contamination of water, air, soil and obviously also the human organism. PFAS have even been found in human breast milk.

Now we also find it in ketchup, yes, that very common condiment, widespread especially among young and very young people.

Mamavation collected 12 brands of ketchup between August and September 2021 and sent samples of each to an EPA-certified laboratory, which used total fluoride determination, with a detection limit of 10 parts per million (ppm). , below which it would have been impossible to find it. In cases where it was suspected that the substances were present in the plastic, the laboratory also analyzed this, but in none of the cases did it find any trace of fluoride here.

Our findings have brought some bad news - the site reads - Beyond the 65% of the store-bought ketchup we tested produced detectable levels of fluoride, indicating possible PFAS. This potential contamination in production appears to be widespread in the ketchup industry. We strongly suggest that these brands immediately begin independently testing their product inside the box, identifying where these potential problems are coming from, and cleaning up their products and processing methods.

Here are the results, brand by brand.


  • Annie’s Organic Ketchup — 13 ppm
  • FODY Ketchup — 13 ppm
  • Hunt’s Ketchup — 12 ppm
  • Organicville Made With Agave Nectar Ketchup – 15 ppm
  • Primal Kitchen Organic & Unsweetened Ketchup — 15 ppm
  • Sir Kensington’s Classic Ketchup — 18 ppm
  • Trader Joe’s Ketchup — 11 ppm
  • True Made Foods Veggie Ketchup — 16 ppm


  • 365 Whole Foods Market Tomato Ketchup — <10 ppm
  • Heinz Organic Certified Tomato Ketchup — <10 ppm

Toxic quantities? We cannot say yet, and it is not even known if and how accumulation effects can be generated. Also not known are the long-term ones.

We shouldn't release these man-made substances into the environment because they circulate in water systems. Some transform into more damaging PFAS before returning to the air from the oceans, then returning to the mainland. The upstream solution is not to use these persistent chemicals in the first place

he had declared  Ian Cousins, environmental chemist at the University of Stockholm.

How to avoid them then? Unfortunately, PFAS are really everywhere, but in the meantime, if we love ketchup, the only safe solution seems to be to prepare the condiment at home.
