Lead Intoxication Related to Coriander Consumption: A Case Report From the United States

Spices are associated with health risks, including heavy metal exposure. We present a case of lead intoxication likely related to spice consumption, specifically coriander powder. A 61-year-old woman was diagnosed with lead intoxication during a medical evaluation for symptomatic anemia. The patient had regularly consumed imported Malaysian spices prior to symptom onset. An initial public health assessment revealed only modest concentrations of lead in spices found in her home, raising concerns about additional sources of exposure. Several months later, a relative of the patient was also diagnosed with lead intoxication. Investigation revealed markedly elevated lead concentrations in coriander powder consumed by the relative, suggesting potential economic adulteration. The index patient reported also consuming coriander purchased from a Malaysian street market prior to her lead toxicity diagnosis. Spices are susceptible to heavy metal contamination from inadvertent environmental uptake or intentional economic adulteration. Medical professionals should remain vigilant for lead-contaminated spices and collaborate with public health officials to identify sources and patterns of lead exposure.
