FDA STATEMENT
JULY 2024
THE EVIDENCE
2024 – 2025
"current scientific evidence does
not demonstrate that levels of
microplastics in foods pose a risk
to human health."
— FDA.gov, July 2024
FEDERAL ACTION TAKEN ON MICROPLASTICS:
2015
Microbead-Free Waters Act
bans microbeads in rinse-off cosmetics only
2024
One webpage published
no food regulations · no packaging limits
today
monitoring the situation
no concentration limits in food or water
that is the full extent of federal law
plastic found in every major organ
brain · liver · kidneys · heart · placenta · testes
brain plastic up 50% every 8 years
Nature Medicine 2025 · University of New Mexico
240,000 particles per litre of water
marketed as "pure" and "natural" · PNAS 2024
dementia patients: 3–5× more brain plastic
concentrated in blood vessel walls
plastic blocks capillaries · triggers clots
neurological abnormalities in mice · Sci Adv 2025
immune cells absorbing plastic particles
immune system weaponized against itself
none of this is sufficient for the FDA to act
vs
same playbook as tobacco · lead paint · PFAS manufacturers

"the amount of plastic we found in one brain weighs roughly the same as a plastic spoon" — Matthew Campen, UNM
