The document addresses the current status of mitigating dietary arsenic exposure in the United States and presents recommendations for improving public health protection. It discusses arsenic’s significant health risks, including cancer, cardiovascular diseases, and developmental impairments, especially in vulnerable populations such as children. The document points out the regulatory gaps in existing arsenic standards, particularly in foods. Regulatory agencies like the FDA and EPA focus primarily on drinking water, while arsenic levels in foods such as rice and rice-based products often go unaddressed. The review calls for setting specific, enforceable limits on arsenic levels in high-risk foods, along with a comprehensive, systematic approach to reduce exposure.
Who is affected?
Consumers, especially those who consume high quantities of rice or rice-based products, are the primary populations affected by arsenic exposure. This includes infants and children, who are more vulnerable to arsenic’s toxic effects, particularly through their diet. Food manufacturers also play a crucial role in these efforts, as they are responsible for ensuring that their products comply with new safety standards and limits for arsenic content. Public health officials and regulatory bodies like the FDA and EPA are also key stakeholders in this issue, as they are tasked with establishing, monitoring, and enforcing regulations related to arsenic levels in food. Communities in areas with high arsenic contamination in water are at an elevated risk.
Most important findings
The study identifies several key concerns with arsenic exposure in food. Current regulations mainly focus on drinking water, leaving a significant gap in the protection of consumers from dietary arsenic exposure. The FDA has set limits for arsenic in some food items, such as rice-based baby foods, but lacks consistent guidelines for other food products. Long-term exposure to inorganic arsenic has been linked to several serious health issues, including cancers and developmental effects, particularly in children. The document calls for setting stricter limits for arsenic in rice and rice-based products, given their prevalence in the diets of children. It also emphasizes the need for updated risk assessments to better understand how arsenic affects public health, particularly in vulnerable populations.
Key implications
The findings have significant implications for both public health and the food industry. Stricter regulations are necessary to reduce arsenic exposure, particularly in rice and rice-based products, which are major sources of arsenic in the diet. Food manufacturers must adapt by ensuring their products meet stricter arsenic standards, particularly for infant and children’s foods. Regulatory bodies like the FDA and EPA must work to close existing gaps in arsenic regulations and set enforceable limits on arsenic in food, using risk-based models to determine safe levels. For public health, this means fewer cases of arsenic-related diseases and a reduced burden on healthcare systems. More comprehensive monitoring, better consumer education, and proactive public health policies are needed to protect vulnerable populations from the harmful effects of arsenic exposure.

Arsenic is a naturally occurring metalloid that ranks first on the ATSDR toxic substances list. Inorganic arsenic contaminates water, rice and consumer products, and exposure is linked to cardiovascular disease, cognitive deficits, low birth weight and cancer. HMTC’s stringent certification applies ALARA principles to protect vulnerable populations.
