Accidental boric acid poisoning following the ingestion of household pesticide.

Borate-containing compounds were formerly used as topical antiseptics and were components of many medicinal preparations including skin powders and ointments used for the treatment of burns and diaper rash. These compounds were also used as irrigants for body cavities, including the pleural, vaginal, and rectal cavities. These applications were subsequently discontinued by the medical community when the toxicity and potential lethality of borates were recognized. Although documented cases of borate poisoning are now rare, the chemical is still an active component commonly used in high concentrations in household disinfectants/cleaners, pesticides, and wood preservatives. While the majority of documented borate-related deaths have occurred in infants, the toddler population is currently at risk due to possible exposure to these household products. We present the case of an 18-month-old child who died following the accidental ingestion of a boric acid-containing, commercially available roach pesticide product.
