Can PFAS from everyday products affect children's immune response to antibiotics?
Possibly. A 2025 study linked early PFAS exposure to increased antibiotic use in children, suggesting immune system effects.
What's actually in it
PFAS from nonstick cookware, food packaging, and water-resistant fabrics accumulate in children from before birth through breastfeeding and diet. These chemicals are known to affect immune function in lab studies, potentially making children more susceptible to infections.
What the research says
A 2025 study in Int J Hyg Environ Health from the Odense Child Cohort tracked PFAS exposure from pregnancy through early childhood and compared it to antibiotic prescriptions. Children with higher PFAS exposure needed more antibiotic courses, suggesting their immune systems were less effective at fighting infections on their own.
Reduce PFAS exposure by filtering water, using PFAS-free cookware, and choosing untreated fabrics for children's clothing and bedding.
