Summary
Paediatric specialist Dr. Poon Kam-ha has addressed parental concerns about lead contamination in infant formula, explaining how lead enters milk powder and why babies are particularly vulnerable to its effects . The article, published under the "Medical Good Companions" column, emphasizes that while contamination can occur at multiple production stages, parents should not panic but should take practical preventive measures .
Key Points
- Lead contamination can originate from polluted soil, water, or feed near dairy farms, or from contaminated plant-based nutritional additives used in formula production .
- Manufacturing equipment, factory water sources, metal cans, and packaging coatings can all introduce lead during processing and packaging stages .
- Infants absorb lead more readily and excrete it more slowly than adults, with their immature blood-brain barrier allowing easier access to developing brain tissue .
- Chronic low-level lead exposure may cause no visible symptoms initially, yet can still impair cognitive development, behaviour, hearing, vision, and growth .
- Blood testing is the only reliable method to assess lead exposure; urine and hair tests are unreliable, as lead can accumulate in bones for 10 to 20 years .
Why It Matters
Hong Kong parents who have used recalled formula batches should stop immediately and consult a doctor with product details and feeding history, rather than relying on visible symptoms . Beyond formula, old building pipes, peeling paint, and substandard toys represent additional lead exposure risks in local households, making environmental awareness crucial for infant protection .
