Aren't microplastics already in chickens? Do they get passed to the eggs? If so, where do you filter microplastics first. . . the chicken or the egg?

Don’t buy cheap eggs. The plastic is introduced via the feed, through vectors like expired bread products. There’s nothing wrong with using expired baked goods. The issue comes when they don’t take off the plastic wrapping and just let everything be shredded into the feed.

I do not believe grass fed chickens have the same problem.

I strongly doubt they shred the plastic packaging into the feed. That said, plastic is already in everything. It's in our blood, in the placenta of fetuses. I think you'd be hard-pressed to find a chicken that doesn't have microplastics in its blood.

Grass fed chickens also contain microplastics. So does every living organism these days.

What you refer to is literally feeding them plastics. Which I hope is a myth but would totally not surprise me at all.

My, my, a new chicken and egg problem!

But seriously, this does raise genuine concerns about what is the acceptable limit for microplastics in the egg whites initially, since microplastics have made way to everything we consume today.
