Researchers find gut bacteria rapidly soak up ‘forever chemicals’

Scientists have demonstrated that select human gut bacteria can bioaccumulate and sequester PFAS ‘forever chemicals’, increasing faecal excretion in humanized mice. The findings reveal a potential microbiome-based strategy to reduce PFAS body burden, though clinical benefit in humans remains unproven.
