The report provides a comprehensive review of the prevalence of lead exposures from consumer products in four US jurisdictions: California, Oregon, New York City, and King County, Washington. This analysis compares the relative contributions of consumer products versus traditional housing-related sources such as lead paint and plumbing in children’s elevated blood lead levels (BLLs) over a period from 2010 to 2021. The study found that consumer products, which include items like spices, jewelry, ceramic cookware, toys, and traditional medicines, are increasingly recognized as significant sources of lead exposure in vulnerable populations, particularly immigrants and refugees who may bring these items from abroad.
Who is affected?
The primary affected populations are children, especially those from immigrant and refugee communities, as these groups are more likely to be exposed to lead-containing consumer products that are often imported or hand-carried during travel. These communities are particularly at risk due to the use of culturally significant products such as traditional medicines, jewelry, and spices, which are not always subject to the same regulatory oversight as domestic products. Health authorities and agencies involved in lead poisoning prevention programs, such as the US FDA and local health departments, also play a key role in identifying and addressing these exposure sources.
Most important findings
The study reveals that the proportion of lead poisoning investigations identifying consumer products as the source of exposure varied across jurisdictions, ranging from 15% to 38%. Consumer products were found to be just as significant as housing-related sources in California and Oregon in 2019. Notably, many of these products are sourced from low- and middle-income countries (LMICs), with high concentrations of lead often found in products like spices and traditional remedies from countries such as India, China, and Mexico. The report also highlights the limitations of current regulatory frameworks, which often fail to address the full scope of exposure, particularly from products imported into the US through informal channels, such as personal travel. Inconsistent regulatory actions across states and localities compound this gap in oversight.
Key implications
The findings suggest that while significant progress has been made in reducing lead exposure from traditional sources like housing, consumer products are increasingly becoming a major contributor to elevated BLLs in children. This shift calls for more comprehensive regulatory frameworks that specifically address the risks posed by imported consumer products. The report emphasizes the need for better data collection, including a centralized national surveillance database for tracking lead exposure from consumer products. Additionally, it calls for more stringent enforcement at the point of entry into the US, such as through the expansion of FDA import alerts and broader international collaboration to limit the production and export of lead-containing products.

Lead is a neurotoxic heavy metal with no safe exposure level. It contaminates food, consumer goods and drinking water, causing cognitive deficits, birth defects and cardiovascular disease. HMTC’s rigorous lead testing applies ALARA principles to protect infants and consumers and to prepare brands for tightening regulations.
