Baby Safety / Compounds / DDT (dichlorodiphenyltrichloroethane)

Is DDT (dichlorodiphenyltrichloroethane) safe for babies and kids?

High risk for kids

Infants accumulate DDT (dichlorodiphenyltrichloroethane) through breast milk (bioconcentration), placental transfer, and dust ingestion. Persistent pollutants concentrate in fatty tissues with extended half-lives in developing organisms.

Risk for babies

High risk

Infants accumulate DDT (dichlorodiphenyltrichloroethane) through breast milk (bioconcentration), placental transfer, and dust ingestion. Persistent pollutants concentrate in fatty tissues with extended half-lives in developing organisms.

Neonates and infants up to 12 months have incomplete blood-brain barrier development, immature Phase I/II metabolic enzymes (particularly CYP3A4, UGT1A1), and higher gastrointestinal permeability. Equivalent doses produce higher internal concentrations and longer residence times.

What to do: Minimize infant exposure through source control. For breastfeeding mothers: reduce maternal exposure. For formula-fed infants: use certified low-migration bottles and verified water sources. Consult pediatrician regarding any concerns.

Risk for pregnant and nursing people

Elevated risk

Placental transfer; preterm birth; DDE disrupts progesterone signaling.

Regulatory consensus

11 regulatory and scientific bodies have classified DDT (dichlorodiphenyltrichloroethane). The classifications differ — that's the data.

AgencyYearClassificationNotes
IARC2015Group 2A (probably carcinogenic to humans)Breast cancer, NHL; Monograph 113; reclassified from 2B
US EPA1987Likely to be carcinogenic to humansLiver tumors; banned US 1972; still globally used for malaria control
EPA CTX / IRISB2 (Probable human carcinogen - based on sufficient evidence of carcinogenicity in animals)
EPA CTX / NTP RoCReasonably Anticipated to be a Human Carcinogen
EPA CTX / IARCGroup 2A - Probably carcinogenic to humans
EPA CTX / EPA OPPGroup B2 Probable Human Carcinogen
EPA CTX / CalEPAKnown human carcinogen
EPA CTX / GenetoxGenotoxicity: negative (Ames: negative, 4 positive / 6 negative reports)
EPA CTX / GenetoxGenotoxicity: negative (Ames: negative, 4 positive / 6 negative reports)
EPA CTX / Skin-EyeEye Irritation: Category 2B (score: moderate)
EPA CTX / Skin-EyeSkin Irritation: Not classified (score: low)

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
