Doing whole blood donations seems to significantly reduce PFAS in the blood. Here's one paper:

Edit: This also helps others who are in accidents, car wrecks, have Cancer, etc. Yes, we pass on the PFAS to others, but the immediate need for blood is more urgent than the potential long term impacts of PFAS.

Bloodletting making a comeback? And having actual benefits this time?
I used to donate blood regularly but now that I'm in Japan they require me to be decently fluent in Japanese to "understand" the risks, despite having done it a bunch of times in other countries (and other medical procedures not requiring Japanese knowledge).
My girlfriend accidentally told the donation center she went to Mexico, and they banned her from donating for four years.

Apparently you'd only go to Mexico to eat brain tacos and share needles with cows. Surely there's a better way to filter out risky blood.

I wonder what it would cost in the US to have a pint of blood taken - I can't donate. Guess I could do it myself...
Do blook banks have a way of filtering out PFAS? Or are we giving each other forever chemicals through blood donations?
> we pass the PFAS to others

Is there no way to filter them out of withdrawn blood?

Aren’t we just donating the PFAS to potentially sicker patients?
Reason #136 for why tech-bros need a blood boy to infuse from daily.
EPA already set a Maximum Contaminant Level of 4.0 ppt. That's why they moved most PFAS production to China.
Another issue is that sewage sludge and "biosolids", unknowingly containing PFAS, is/was being used as farm fertilizer, causing some farms to have to be written off for food production. I would expect many more farms in the future to be found with PFAS soil levels exceeding what is safe to produce food with. The only way to find out is to test.

> The practice of spreading sludge as a soil amendment has been a common practice in Maine and across the nation for decades. Land application of sludge material occurred long before there was knowledge that it may contain PFAS or the health implications of PFAS.

In drinking water, yes. And the EPA coordinated a "voluntary" phase-out of PFAS in packaging, but it is not enforced.

Is there a limit in food, which is what this petition was about?

if a request doesn't come with a minimum $2 Million check attached or crypto transfer, nothing will get done this decade

it's going to be a health and science dark ages for US

The EPA first issued health advisories around PFASs in 2009. Why didn’t these folks file this petition sometime during the 12 years since then where it likely would’ve gotten a more favorable reception?
Because we learned more, gathered more public concern, and then acted?

If there’s not a eureka moment of knowledge, should we do nothing?

Because the EPA called it the "2010/2015 PFOA Stewardship Program" not the "2010/2015 PFAS Stewardship Program" PFAS != PFOA
I feel like most people hadn’t heard about them until a couple of years ago.
2009 is a generation ago. Asking why a new generation why they might not have petitioned 17 years ago seems like asking where a 21 year old was on 9/11.

As for a better reception, the assumption was RFK Jr. would take it more seriously.

whataboutism is a tiresome argument.

Lets agree that these folks are wrong and ideally they should have petitioned 12 years ago. The question to ask is - for an admin which loudly claims to make America healthy again and talk about making everything chemical free etc - why can't they pass this? Is it because they can't score brownie points with base or they are overtly corrupt and do the same thing they accuse others of doing? Or that they know their supporters will not look at the validity of the claim and instead discredit people by asking whataboutism and party line questions?

Because the majority of Americans are too stupid and too lazy; they won't bother until the threat is literally killing them.
> Why didn’t these folks file this petition sometime during the 12 years since then where it likely would’ve gotten a more favorable reception?

Because then The Uniparty would look bad.

Instead, we can prop up the illusion of democracy and point fingers at "the other side" of good cop / bad cop while elites poison everybody more. We wouldn't want people living too far beyond their working years, after all.

What happened to MAHA?
It got deprioritized in favor of campaign donations, cryptocurrency investments, and general money inflow from PFAS industry lobbyists!
Not surprising at all. What are "action levels" supposed to do? It's basically a helpful suggestion to take action, but you don't have to. FDA obviously doesn't care about the well-being of anyone.
The decision has got to be 100% political. The level and damage could be 1000x and they still won't act if it makes them money in the form of corporate campaign donations.
Short of frequent blood donation, is there any reasonably adoptable life change a person can make to meaningfully reduce expected PFAS intake, or is it best to try not to think about it?
Yes, there are a few things you can do. In rough priority / proven benefit order:

1. Eliminate as many items as possible from your diet that make use of PFAS based components, such as plastic linings. This means don't buy groceries packaged in lined packaging, this means don't cook with Teflon pans, and it means don't drink water from plastic bottles or bottles lines with plastic.

2. Get a whole-home water filtration system that is certified (NSF 53 or similar standard) to reduce/remove PFAS and if possible, on top of this do under-sink RO for drinking/cooking which is certified (NSF 58 or similar) to remove PFAS and use glass or stainless steel reusable water bottles to take water outside your home.

3. Exercise regularly so that you sweat and drink lots of appropriately filtered water, donate blood and/or plasma regularly.

4. Eliminate clothing or other items in your wardrobe that are coated with DWR or similar coatings. Don't make use of any PFAS-derived treatments/plastics in your clothing. This is especially important during the process of washing your clothes, as this generates microplastics which are PFAS contaminated and you can ingest them via breathing.

Everything else is basically guesswork, these are the only things known to have any benefit. We mostly ingest PFAS due to contamination in the food and water supply. This contamination is unavoidable, but we can greatly reduce exposure by making smarter choices about packaging materials and cooking methods, and a big one is simply not drinking anything that you can't confirm has been properly filtered and packaged.

I'm a bit extreme, I even brew and bottle my own beer and other beverages like soda and water kefir/kombucha to avoid exposure to externally packaged products that may be contaminated with PFAS.

i've heard some water filters can take out pfass, and a lot of it comes from food containers (i guess takeout items etc) and non-stick cookware, water-proof clothes [0] so probably good idea to avoid those...

The article fails to mention risk and the amounts that create those. In typical journalist fashion it just emphasizes the word “chemical” and other scary framings.
True. The risk is heavily downplayed, since the health effects manifest in decades and can be blamed on lifestyle factors, while the amounts causing health issues are in the order of parts per trillion.
Well it is scary and harmful. Since it accumulates in the body, the safe level is zero. Do you work for the chemical industry?
I wonder how much teflon wears off the die into the spaghetti on pasta extrusion machines.
I don't know why people eat pasta, considering bulgur wheat is pretty good, is easy to cook, also cooks in the microwave, and is much less processed. I like bulgur wheat a fair bit.
I mean what did we expect? This admin’s entire MO has been dismantle or de-fang what little regulatory framework we have left.

Did they really think RFK Jr. was ushering in a healthier, “more natural” America?

Yes. But of course "healthier" is describing the health of brain worms. On the bright side, this probably indicates that the reactionaries' pushes to lower the intelligence of the population are reaching a point of diminishing returns, as they've now had to turn to parasites to continue the trend.
Turns out it's easier to make conspiracies than effective policy. Who knew?
Would dousing someones food with PFAS be in any way illegal if FDA deems PFAS safe ?
No Tylenol for y'all, but I'll shout the whole bar another round of PFAS!

> They have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease and a range of other serious health problems. They are dubbed “forever chemicals” because they can persist for thousands of years in the environment, and are designed to be indestructible.

But _not_ autism! Autism is the great evil we have chosen as our individual health enemy. I don't see autism listed, you may pass.

Whenever I see something like this, I'm always curious how the libertarians rationalize their world view. Because this is what they want: no regulations where companies can do whatever they want. And they will.

We're witnessing the looting of America. Every level of government seems increasingly dedicated to transferring wealth from the taxpayer to the wealthy. But even that's not sufficient. Apparently the wealthy also need to poison the land and people too for an uptick in profits. Why should they care? Capital is mobile. They'll simply leave whenever society collapses.

MAHA … am I right? What a joke!
From the article:

>The agency said it plans to set less non-binding “action levels” that do not require contaminated food to be removed from shelves. “Tolerance levels”, or limits, make it illegal to sell food contaminated beyond a set threshold.

From the FDA

>Action levels and tolerances represent limits at or above which FDA will take legal action to remove products from the market.

Typical junk tier rage bait journalism you can expect from the guardian.
