So basically the gloves that kitchen staff now must wear means we get an extra dose of micro plastics? Yikes.

> So basically the gloves that kitchen staff now must wear [..] Genuine question: we used to simply wash our hands well before preparing food. At what point did the wearing of disposable gloves become "better"?

It's not better, it's a lazy shortcut so they have to wash their hands less and don't feel gross touching raw meat.

Classic. This is like that female serial killer in Europe that turned out to actually just be DNA from a woman making the DNA collection swabs.

When your methods get really sensitive, you stop just measuring the world and start measuring your own process too

The problem isn't just the plastics themselves. Plastics are chemical "sponges" that will soak up pollutants over time from the environment (brominated fire retardants, bisphenols, PBCs, pesticides, phthalates, heavy metals, etc) and deliver them in a concentrated dose into the body. Even if plastics of all sizes are 100% biologically inert, they're still a Trojan Horse for other toxins. https://www.sciencedirect.com…

>Roughly 50% of indoor dust is composed of microplastics, so it's not like it's uncommon. I highly doubt that. Soil, skin and pollen are usually the big ones. Hairs depending one how you count dust, but eliminating hair like fibres would also eliminate most of the sources of plastic, unless you allow really large particle sizes. [edit] Checking research. The highest claim I found was 39% of fibres (in household dust,…

Synthetic fibers from clothes are microplastics, and clothes shed lots of fibers. Not to mention all the upholstered furniture, carpet, rugs, drapes, bags, etc.

I don't think anyone will claim microplastics don't exist, but people will definitely be skeptical of articles about how many there, and where they're found. At worst, I'd expect to see people disregarding the threat, not disregarding the presence of the microplastics themselves.

I'm not sure if they have established a threat. I thought it was mostly hypothesised or very locally specific harms. On the other hand I suspect much of the real science on environmental plastic might avoid the term microplastic since it seems to have a meaning that flows to whatever can make the scariest headline today. I have seen the size range to qualify run from microscopic up to a couple of millimetres. Volumes…

Funnily, I believe the glove mandates for food prep are actually anti-hygiene. Unlike bare skin, you can't really feel when your gloves are contaminated. So you are less likely to replace gloves when you should. With bare hands, you can feel the raw chicken juices on you, so it's pretty natural to want to wash your hands right after handling the raw chicken. Gloves are important in medicine, but that's with proper us…

Uh yea. That’s why most places use washed hands not gloves.

I’ve never seen for example sushi portrayed with anything but bare hands

This study assumes everybody is oblivious to contamination, and explicitly says they can't differentiate. Not useful and bordering on the tautological

The non-trivial part isn't contamination per se, it's that the contaminant is chemically and spectroscopically similar enough to evade standard discrimination

To the contrary. You take off and throw out your gloves every time you finish doing something with raw meat. It's procedure. It's habit.

You're never relying on "feel" to determine whether there are "raw chicken juices on you". Using "feel" is not reliable.

I don't know why you think food service workers aren't constantly putting on new gloves, but doctors and nurses are. Like, if you're cutting up chicken for an hour you're not, but if you're moving from chicken to veggies you absolutely are.

I'm amazed that wasn't taken into account! Many years ago, in the final year of my Biology degree, I did a paid summer internship at an Evolutionary Biology lab here in Spain, assisting in a project where they were researching relationships between metal ion accumulation (mostly zinc) and certain SNPs (≈"gene varieties"). A lot of my work was in slicing tiny fragments of deep-frozen human livers and kidneys in a bios…

>>That some research on microplatics did not take into account the absolutely mental amount of single-use plastic that is involved in biological research, particularly gloves of all things, boggles the mind

What boggles the mind is you commenting on an article you clearly did not read...stating something that is not there...
