Thallium poisoning, Iraq

Two Iraqi families developed symptoms of thallium poisoning after consuming a meal on January 21st. Patients have been transferred to Amman for care at the Jordanian Hospitals. The Poison Laboratory in Baghdad had detected thallium in specimens taken from patients and foods. Ten family members were identified as cases; all presented with abdominal pain, vomiting and dysphagia. Within 4 days, 9 [90%] case-patients developed lower extremity pain and paresthesis and hair loss. Three case-patients died and one is clinically dead [case fatality rate=40%]. Median onset of illness was 24 hours [range: 12-72 hours]. WHO has sent blood, urine and cake specimens to Birmingham; Toxicology Laboratory to confirm and measure the concentration of Thallium in different specimens [according to IATA regulations to ensure the safe delivery of the specimens]; and facilitated procurement of Prussian blue antidote through contacting the UK Department of Health as it was not available in Jordan and neighboring countries. Intentional contamination is suspected and a legal investigation by authorities in Baghdad is underway. Information and results from this investigation are still pending.
