PlasticList – Plastic Levels in Foods

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:

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.

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.
