This rang my "fraud" detector in my head:

1. a random .org site that sounds too much like rah rah save the children

2. spammed across many news sites and reddit and now hacker news all in a short time span

but after reading the report it seems pretty good

The take-away I got was buy rice grown in California, Thailand, or India. Soak beforehand if you really want to reduce bad stuff

Thanks for reading the report and providing the tl;dr.

Another thing that caught my eye as I scanned the article was "rice products" which is obviously not just rice, and levels exceeded for "infant rice cereal".

So, it did sort of seem aimed at the market of inducing panic in new moms.

Also rice is a lot worse than other grains and brown rice is worse than other rice. Asian people in particular should diversify their diets. I'd note that Asian-Americans already have high PFAS levels because they use rice cookers.

Do you have a source about PFAs from rice cookers? My understanding is that Teflon in cookware, used at recommended temperatures, doesn't release PFAs. It's the Teflon manufacturing process that releases PFAs.

Teflon rice cookers don't really release PFAS at appreciable levels. Teflon is remarkably stable (and one of the reasons it was DuPont's miracle discovery).

PTFE's degradation point is 260C, but rice cookers only cook up to 100C (controlled).

The only source of PTFE is if they scratch or flake off over time, but this is usually visible.

Teflon cookware are more problematic in non-stick pans, where they do get heated to higher temperatures, especially for stir fries.

This doesn't blame rice cookers but it points out a large difference
