The Biden administration's recently announced plan to replace all lead pipes in the U.S. is a reminder that the toxic metal remains a threat, even in a country that has largely banned its use. The smallest levels of lead exposure can cause a range of health damages over time, especially to children's brain development. Stanford researchers Stephen Luby and Jenna Forsyth have spent years examining the widespread presence of lead in low-income countries, including in some commonly consumed products. They led a perspective published Nov. 5 in The Lancet Public Health that tallies lead's global health and economic costs, and a study in the November issue of Science of the Total Environment that highlights the urgent challenge of lead contamination in South Asian turmeric.

"Lead is a remarkably harmful toxin," said Luby. "Even within the context of limited resources, we have to find ways to focus on reducing exposure to it."

Below, Luby, the Lucy Becker Professor of Medicine in the Stanford School of Medicine, and Forsyth, a research scientist with the School of Medicine, discuss the prevalence of lead-tainted products, and share insights on how food safety policies, education, and lead-free alternatives could reduce the risks.
