PlasticList – Plastic Levels in Foods

dredmorbius

One class of items not listed here, which I'd recently started to think might be less-than-optimal: pepper sold in jars with built-in, plastic, grinders.

I'd long since noted that as the jar emptied the grinders were increasingly ineffective. Thinking on why that might be ... I realised that this was because as you grind the pepper, you're also grinding plastic directly into your food.

There's surprisingly little discussion about this that I can find, though this 5 y.o. Stackexchange question addresses the concern:

<https://cooking.stackexchange.com/questions/103003/microplas...>

Seems to me that plastic grinders, whether disposable or sold as (apparently) durable products, are a class of products which simply shouldn't exist.

Searching, e.g., Walmart for "plastic grinders" turns up five listings presently, though it's not clear whether it's the body or the grinder itself which is plastic. In several cases it seems to be the latter.

Peugeot—yes, they of the cars—make an excellent line of steel-based pepper grinders, and a great nutmeg mill as well. Along with hoop skirts and lawnmowers and much more, apparently, over the 200 years since the family started their first steel mill:

https://us.peugeot-saveurs.com/en_us/inspiration/history/

The car business sold to Stellantis, but the lineage’s kaleidoscope of other enterprises apparently continues.

SchemaLoad

Ikea makes one with ceramic burrs which also solves the issue most of them have where the grinder faces down and drops grinds on your table.

alliao

definitely one of those buy it for life type of thing, very satisfying once you get used to it, and it does take time to get used to it. the labelling is carefully designed to fade away just around the time you got to know how to use one, masterfully done lol

giraffe_lady

The mechanism is probably good forever but the bottom ring is liable to crack over time. They usually last me a decade or so which is fine for the price.

andruby

I love them and have bought half a dozen over the years. My dad gifted me one when I moved out decades ago.

A good pepper grinder (and the Peugeot’s are top notch) is such an obviously valuable purchase. Lasts a decade and fresh pepper from a good grinder is much tastier. One of the best $35 to spend imo

rsync

meh. I like the aesthetics of the Peugeot grinder but it is flawed.

Specifically: the grinder top is not mated with reverse threads. This means the act of grinding loosens the top. I have to stop and re-tighten quite frequently.

I suppose the design is perfect if you are left-handed ...

giraffe_lady

If it were the other way it would tighten with use and eventually strip the threads or crack the wood top. Anyway it's an almost unbelievably petty bit of cooking technique but there is actually a "correct" way to hold and turn a pepper grinder lol.

Your palm is meant to hold the nut in place. On the old ones the tightness of the nut was the control for fineness so it was necessary to hold it as you turned anyway. They moved that control to its own thing on the bottom a few decades ago (iirc) but kept the rest of it the same.

agotterer

Thanks, I hadn’t considered the plastic on the pepper grinder. Guess I’ll be looking for a new pepper grinder as I continue my pursuit of removing plastic and dangerous chemicals from the kitchen. So far the pans, tupperware, and cooking utensils have all been replaced.

While not food, another not so frequently talked about plastic exposure could be clothing dryer vents pushing materials from synthetic clothing into the air. It’s likely less of a problem than the rubber tires on our cars making their way into the air. But it was something that occurred to me while cleaning out the dryer vent this past weekend.

hedora

I’m definitely buying natural fiber clothing moving forward for this reason.

However, I wonder how bad eating bits of the plastic burr grinder actually is. Presumably, they mostly pass through. Stomach acid probably leaches a bunch of stuff, but is it worse than (say) canned tomatoes that were sitting in a plastic liner for a year? I’d wager the grinder bits have a lot of surface area from scarring. That’d increase leaching.

Anyway, I strongly recommend small turkish-style grinders:

https://bazaaranatolia.com/products/turkish-grinder-pepper-m...

(No idea if this brand is decent; the form factor is great, especially for $14)

It has roughly a single-recipe capacity, so I stick crushed red pepper flakes, cumin seed, celery seed, black pepper kernels, etc in it per the recipe, then grind until it is empty. The burr on the one I linked is metal.

I’d probably prefer stainless body + whatever is commonly used for espresso grinders, assuming such a gadget exists.

kube-system

> (No idea if this brand is decent; the form factor is great, especially for $14)

> These grinders are made of Zamak (brass and zinc)

If it's real brand-name ZAMAK, then it should at least be low in lead :)

johncole

Your biggest exposure is going to be water, hands down. What you store it in, how you filter it, these are going to be major sources of plastics and pfas.

skrtskrt

Yes and PFAS/PFOS is now getting directly linked to rise in colorectal cancers.

Personally I would prioritize water filtering for PFAS over microplastics worries if you have limited budget to start changing consumption patterns.

dombesz

I wonder why do you think that? According to the website, unfiltered tap water is not really bad. Am I missing something?

dpflug

I've been using a mortar and pestle. Easy to control fineness and no plastic to be concerned with.

leptons

Same here. I am going to disassemble the cheap pepper grinders I recently bought to make sure there is no plastic in the grinding operation.

I switched to bamboo toothbrushes from plastic a while ago, before de-plasticizing was really a thing. Now I'm glad I did, because plastic bristles grinding against my teeth seems like an easy way for plastic to get inside my body. The bamboo toothbrushes are pretty nice too, the bristles are soft but firm, and the handle is made of bamboo too.

alwa

Personally, I spit out whatever happens when I brush my teeth. But bamboo does sound like a more pleasant experience all the way around.

Gigachad

All disposable grinders are going to be plastic, and likely none of the refillable ones will be since the plastic burrs only last one usage before they are all chipped off in to your food.

andruby

Mentioned elsewhere too but Peugeot (yes the car company) has been making top quality affordable pepper grinders for over a century.

The simple wooden ones last a decade or longer and cost about 35 $/€/£

fragmede

Your teeth seem pretty hard though, to the point that a specialist has to go over them with metal tools every year to clean them.

jihadjihad

Kind of surprised there’s no mention of Fletchers’ Mill [0] here, they’re good quality mills made in Maine. The pepper mills use stainless steel while the salt mills use nylon (corrosion resistance), so you’d have to look elsewhere for salt.

Personally I just dump kosher salt into a salt cellar and call it a day but I am sure there are plastic-free salt mills out there somewhere.

williamdclt

The grinder itself is almost certainly always plastic in these. Even in refillable grinders, in the low-medium range the burr is often plastic

dredmorbius

It's (thankfully) still possible to buy all-metal grinders, ensuring one a reliable source of dietary steel.

Krell or otherwise.

adriand

I use a mortar and pestle (both made of stone) and would highly recommend it!

efskap

It's a dream of mine to learn enough stoneworking to turn a pair of stones from a local river into a mortar and pestle, ideally without contracting silicosis at the same time. Much cooler than shipping granite mined and cut on the other side of the globe.

fuzztester

good option.

i like that too.

metal ones are also available in india, made of stainless steel and maybe other metals instead.

traditionally, people in india used a thick flat wide stone and a thick cylindrical stone grinder applied back and forth on top of the lower stone, to grind spices, onion, ginger, chilllies, turmeric, etc., into a paste or masala, which was then used in making curries, sambar, and other dishes.

jodrellblank

Traditionally grinding things with stone ended up with people eating stone which ground their teeth down[1]:

> "A. When soft stone like sandstone was used for milling grain, as the ancient Egyptians often did, residue from millstones could cause a serious problem over a lifetime, said Dr. Robert K. Ritner, associate professor of Egyptology at the Oriental Institute of the University of Chicago. Egyptian teeth have been well studied in mummies, and only the rare mummy had good teeth, said Dr. Ritner, who lectures on Egyptian medicine. ''They usually had heavy abrasion, and were sometimes so worn down at the crown that the pulp or even the root was exposed, which must have been horribly painful,'' he said. The Egyptians were obsessive about cleanliness, using a natural soda compound called natron for cleaning the mouth and sometimes a chewing reed to massage the teeth. They had few cavities, and the damage seen in studies pioneered by the English researcher F. Filce Leek almost certainly resulted from the residue of disintegrating millstones."

here is an image of one such stone pair, not exactly what we had at home, but close:

also called aattukallu in tamil and iman dasta (iirc) in hindi or urdu, but searching for the latter only gave results for mortars and pestles, which are not the same thing as the one above, the ammikallu.

ThrowawayTestr

I got a $7 ceramic pepper grinder from Ikea.

MetaWhirledPeas

Is the plastic you ingest this way significant though? I don't remember the details, but the Veritasium video on this subject suggested that the scraped teflon you ingest from pans is less significant than the plastic that leeches into food in products like microwave popcorn. I assume this has to do with the reaction between the substance being contained (popcorn oil, in this case) and the item containing it (plastic-lined paper).

If the plastic particles are large enough, I assume we pass them.

nosianu

> Is the plastic you ingest this way significant though?

The follow-up question you might want to ask though is: How often do you want to ask that question?

Yes, every tiny little bit is insignificant. That is true for most things, including actual direct poisons.

A better way to look at such discussions is not to assume that this very specific thing you are currently looking at is the one, only complete problem. Remember instead, in these posts we are looking at lots and lots and lots of tiny details, only a tiny part of the whole problem space.

Do you repeat that relevancy question for every single part? The answer, when you split the problem enough, is always "relevance is near zero".

That is the problem of our tiny brains not being able to comprehend the whole, requiring us to look at tiny parts one at a time. When you create the sum, or the integral, of a huge number of rounded-down zeroes you get zero, and now you have the wrong answer for the whole of the problem.

Even big problems consist of a huge number of tiny parts. Asking the summary question on each tiny part is not a good method.

Every tiny bit of plastic we find is exactly just that - one tiny piece of the big picture. By itself and alone it would be inconsequential. If it was just that one single source of plastic particles, we would not have this discussion. We are here, performing such research, having such discussions, because we have a very large number of such tiny pieces. The question of relevancy is for the whole. Whether this one particular piece of microplastic you ate today, which came from your plastic pepper mill, is the tipping point is not a useful or answerable question, it's all of them combined over time.

filcuk

Teflon is typically not the issue, it's very non-reactive and non-sticky (duh), meaning it just passes through. Attaching such material to metal takes some serious chemistry, though.

showerst

Going by the lower limit of 20,000 ng/kg, a 70kg person has a limit of 1,400,000 ng/day for DEHP and 70MM ng/day DEHT.

So am I reading this right you're probably an order of magnitude below the 'safe' limit even if you subsist solely off of RXBars and Sweetgreen? Which is not so far from me at one point in my 30s...

I didn't expect to open this chart and feel _better_ about my plastic consumption, maybe I'm just misunderstanding the chart. It seems even if the limits are 10x too high, you're still probably fine.

markasoftware

The "report" tab on the website shows which items are above federal recommended limits. The vast majority of tested items are within the limits. So yes, if you're only concerned with what the federal government considers safe, the action item is "probably nothing". But the report page also brings up a lot of good reasons to doubt that the federal limits are sufficient.

Centigonal

The "Are the intake limits correct?" section (and the whole report, really) is fascinating and worth a read, but just to provide a concrete example of why federal limits might not be sufficient:

3M began producing PFOA (the most infamous "forever chemical") in 1947. It has been widely used in industry, and many millions of pounds of the stuff have been dumped into waterways since then. PFOA manufacturers were aware of some of the negative health effects of the substance in lab animals in the 1960s. Researchers outside of corporate America began studying PFOA in the 1980s. In the early 2000s, PFOA exposure via drinking water began to get public attention due to a lawsuit against DuPont.

As far as I know, the US government had no recommended limit on PFOA exposure in drinking water between 1947 and 2009.

Since 2009, limits have become progressively stricter. (For the timeline below, I'm quoting https://www.nrdc.org/press-releases/epa-restricts-toxic-pfas... )

In 2009, EPA established provisional health advisories for PFOA at 400 ppt and for PFOS at 200 ppt.

In 2016, EPA set a lifetime health advisory of 70 ppt for PFOA and PFOS combined.

In 2022, EPA published interim lifetime health advisories of 0.004 ppt for PFOA and 0.02 ppt for PFOS.

In 2023, EPA proposed health-based maximum contaminant level goals (MCLGs) for PFOA and PFOS of 0 ppt.

A lot of these chemicals are newer and less well-studied than PFOA, and we may still be in the period where federal limits are hundreds or thousands of times higher than the true safe level.

jvanderbot

There is an option to view the total daily recommendations, and many of the tested-for items do not have one. So, what is OK for those?

But yes, eating even a pound of the 100th percentile food daily seems to have well below the recommended amounts. So - update the recommendations?

xnx

Weird to see how much attention plastics in food are getting despite no(?) evidence of harm vs. something like consuming too much sugar or alcohol, and BPA/BPS in receipt paper (https://www.nytimes.com/2025/06/24/well/health-effects-paper...).

It's very hard to maintain a mental ranked list of health things to be worried about when hypothetical concerns get more attention/coverage the confirmed ones.

chiffre01

"despite no(?) evidence of harm" If you look up most of the chemicals on the list, all of them have suspected health impacts and the most have been confirmed to be harmful in some degree or another.

For example: DEHP - Endocrine disruption, disruptor of thyroid function, Ingestion of 0.01% caused damage to the blood-testis barrier... etc

I came here to be explained to how eating plastic is not only not bad, but actually good for you. And HN, as always, did not disappoint, like the other day when a guy here explained to me that lead is good for you and iron is poison, and if I disagree I should prove it to him.

showerst

Sugar and alcohol are clearly labelled and provide an obvious benefit, so people feel empowered to make that cost/benefit trade-off.

Microplastics do nebulous harm, and it's difficult or impossible to control intake.

cortesoft

Plastics provide an even more obvious benefit than alcohol.

joshuamcginnis

What is the obvious benefit of alcohol?

crazygringo

Relaxation. Stress reduction. Being able to connect with people in a way you might not be able to otherwise.

Obviously, varies dramatically from person to person.

williamdclt

“Obvious” is maybe not quite the word I’d use, but lower inhibition, fun and social aspects are benefits of (a reasonable use of) alcohol

(Not saying it’s a good trade off or that it’s the only or best way to achieve these things obviously)

cpp_frog

bigie35

While you're correct, my freakout lies in the fact that microplastics have been found to bypass the blood brain barrier...

https://www.nature.com/articles/s41591-024-03453-1

SchemaLoad

Sugar and alcohol have had decades of attention and public health campaigns. HN doesn't care because it's not new or interesting news and they are fairly easy to avoid.

kodt

No one wants to consume plastic however, while with sugar and alcohol consuming it is the goal. What is the upside to consuming plastic?

naberhausj

Cheap, ubiquitous plastics have revolutionized every industry (tools, food, automotive, etc...). We wouldn't be able to consume anywhere close to current level without them.

Not saying that's a good thing. But giving up plastics (not just in our personal life, but across the entire supply chain we rely on) would probably be harder for the average American than giving up alcohol for a drunk.

culi

Yeah giving up plastic would be hard but we have to _start_ pushing it in the right direction. A person in 2025 might find it basically impossible to avoid microplastics but if we make changes now someone in 2040 might be able to do it

dineol

I think this new microplastic-in-food hysterics is just another way to milk money on "microplastic free" badges/tags: selling usual items under new "MPF" brand with increased costs.

cg5280

This website does have a column for BPA/BPS and receipts are indeed listed.

johncole

It’s almost impossible to remember to do all the things to keep healthy for sure.

I used to work for a company that makes equipment for the food processing industry.

Sometimes conveyor belts would be left running for days or even weeks in the test area. After a while, you would start to see very fine dust on and around the conveyor belts. This was finely ground POM plastic. On some occasions, there were actually heaps of that stuff forming beneath the conveyor belts.

In the factories, everything gets washed down with pressure washers at least once per day, so very little of this stuff goes into the food, but it definitely gets washed away out to sea.

I think that there is probably a wide-spread misunderstanding on how the micro-plastics enter the food. It does not seem very likely that it would come from the packaging or your tupperware (unless your tupperware is so old that it has actually started to disintegrate). It seems much likelier that the plastics were in the food before it was packaged.

alliao

beats metal shavings I guess...

eestrada

The most disturbing is "Raw Cow Milk from Farm in Glass". It still is loaded with plastic, even though it is one of the least processed things on the list.

My only question is was the cow milked by hand or by machine? The tubing in a milking machine almost certainly contains plastic.

https://www.plasticlist.org/product/29

9rx

> even though it is one of the least processed things on the list.

It is in a glass bottle, so maybe not the greatest example: https://www.sciencealert.com/glass-bottles-actually-contain-...

Straight from the cow would be far more interesting with respect to what you are bringing up, albeit beyond the scope of the broader discussion.

purple_ferret

No chance any commercially available milk is getting hand milked.

giantg2

Many livestock feeds have some level of plastic in them.

dehrmann

Hay is often bound up into bales with plastic twine. Cattle happily eat bits on accident. They used to use wire, but that caused a much more serious problem for the cattle.

CalRobert

Silage uses insane amounts of plastic wrap and then is left in direct sunlight to decay

giantg2

They used to use natural twines like jute, which was better. They really don't eat much of the plastic stuff. The larger pieces of it do kill them (choking, cholic, etc).

kylebenzle

I visited the largest pig farm in Ohio and they grind up bags of old dog food, plastic bags and everything. Literally pallets full of expired food, just dumped into the grinder. Then they spread the waste and sell it as organic fertilizer, plastic is now everything.

cyberax

Milk is really great at extracting plasticizers from plastic. It contains natural fats and emulsifiers, after all.

I'd expect that it can pull all kinds of chemicals from the milking equipment.

xnx

Fortunately, raw cow milk is unnecessary for humans (good for baby cows though!) and easy to avoid.

eestrada

I bring up raw milk because it is minimally processed (I don't even consume it personally). I used it as an example because it shows how much plastic is embedded in the food chain and ecosystem by looking at one of the least processed items on the list.

dmm

It's interesting that several products from the 1920s contain measurable quantities of DEHP, which was apparently first synthesized in the 1930s. How did that happen?

For example, the cocoa powder from the 1920s https://www.plasticlist.org/product/990

giantg2

That is interesting. I wonder if it's a byproduct of another process and the 1930s date was only when it was commercially produced in isolation.

ChaoPrayaWave

Thank you for sharing this data, it is really helpful. Now it feels like microplastics are almost everywhere in life, even breathing and eating are difficult to completely avoid. What we can do is probably to try to understand their sources, and then reduce contact as much as possible, make a little bit of active choices, at least to protect ourselves and our families.

sadcodemonkey

This site has been posted to HN before, but it's definitely interesting to revisit in light of drastic cuts to federal agencies like the FDA, USDA, and CDC.

Independent efforts like PlasticList are probably going to be more and more important as research funding gets slashed and health-related data is suppressed or manipulated.

cheeseomlit

What is the deal with whole foods grass-fed ribeye?

What are they grazing on, plastic lawn turf?

johncole

Beef cows are accumulators. And their feed often contains plastics.

cheeseomlit

Just thought it was interesting considering they are 'grass-fed'. Is that just a lie? Or maybe it's something else, like if they're drinking water from plastic containers that sit in the sun all day

johncole

It's a good point. I'm not an ag lawyer, but I am willing to bet that there's wiggle room in any grass-fed definition set by the USDA.

And you're right, there's also: plastic from water sources, plastic in the field that gets taken up by the gras, supplements given to the cow, plastic in the cutting board the meat was cut in, plastic the meat was wrapped in . . . it's hard to get plastic out of your supply chain.

cjflog

While PlasticList has already tested hundreds of products and found plastic chemicals in 86% of them, laboratory.love lets you crowdfund testing for the specific products you actually buy.

Think of it as democratizing PlasticList's methodology: you choose what gets tested, we handle the logistics of sample collection + lab work, and results are published openly to pressure companies toward cleaner supply chains.

culi

Are you associated with plastic.love? If so you should be explicit about it.

Also, if it's crowdfunded, why am I unable to see any finished results without giving you my email?
