Lead Contamination in Turmeric

Context

A new study has found dangerously high levels of lead in turmeric (much higher than the permissible limits) sold in India, Nepal, and Pakistan.

Key Findings of the Study:

Lead levels in some turmeric samples exceeded 1,000 micrograms per gram (?g/g).
Permissible Limit:
- The permissible limit set by India’s Food Safety and Standards Authority (FSSAI) is 10 ?g/g.
- The World Health Organization (WHO) maintains that no amount of lead is safe for human consumption.
Health Risks:
- Lead is a naturally occurring toxic metal found in the Earth’s crust. It is a toxic heavy metal that disrupts metabolic functions, particularly affecting brain development, intelligence, and overall health.
- Lead exposure can result in lead poisoning, which can cause intelligence loss, learning difficulties, and behavioral issues, especially in children.
- Studies show that children with blood lead levels as low as 5 ?g/dL can face cognitive and behavioral issues.
- Lead chromate, a yellow pigment used in paints, rubber, and plastics, is suspected to be the main source of lead contamination in turmeric. It is often used to enhance the color of turmeric and make lower-quality roots look more appealing.
