Lead intoxication from lead-contaminated water used to reconstitute infant formula
1Division of Clinical Pharmacology/Toxicology, Children's Hospital, Boston, Massachusetts.
Insights
Lead poisoning in infants can stem from drinking water. Preparing powdered formula with contaminated home tap water exposed a 13-month-old infant to high lead levels, highlighting the need for water testing.
Area of Science:
- Environmental Health
- Pediatric Toxicology
- Public Health
Background:
- Lead exposure is a significant public health concern, particularly for vulnerable populations like young children.
- Drinking water can be a primary source of lead exposure, especially when water consumption is high.
- Infants fed powdered formula are at risk if the water used for preparation is contaminated.
Observation:
- A case study identified plumbism (lead poisoning) in a 13-month-old infant during a routine health evaluation.
- The infant's daily powdered formula was prepared using home tap water.
- The home tap water exhibited a first-draw lead concentration of 130 parts per billion.
Findings:
- The infant's lead poisoning was definitively traced to the consumption of powdered formula mixed with contaminated home tap water.
- The high lead content in the tap water (130 ppb) posed a direct toxicological risk.
- This case underscores a critical, yet often overlooked, pathway for pediatric lead exposure.
Implications:
- Routine analysis of home tap water for lead content should be considered when infants are fed powdered formula.
- Healthcare providers should inquire about water sources used for infant formula preparation.
- Public health initiatives may need to address lead contamination in residential water supplies to protect infant health.
Abstract:
The lead found in drinking water can be a source of lead poisoning to young children, particularly those who consume large amounts of water. The authors describe a 13-month-old infant who was discovered to have plumbism during routine evaluation. The lead source was ultimately traced to the daily administration of powdered formula which was prepared with home tap water having a first-draw lead content of 130 parts per billion. This case suggests that whenever infants are fed powdered formula, consideration should be given to analysis of the home tap water for lead content.
