Other studies have also identified spices as a source of lead exposure in US children. The researchers had conducted the study after a string of lead poisoning cases in US children were linked to contaminated spices, including turmeric. Two samples, the only two samples sourced from Bangladesh, exceeded the allowable lead level by two orders of magnitude. In a 2017 study by public health researchers at Boston University, 16 of 32 turmeric products bought in markets in the Boston area had lead levels over the FDA's allowable lead level for candy (the FDA does not have guidelines for lead levels in spices, specifically). Lead chromate is a vibrant yellow substance that has frequently turned up in turmeric sourced from India and Bangladesh. In the FDA's announcement, the agency noted that 'The lead-to-chromium ratio in the cinnamon apple puree sample is consistent with that of lead chromate (PbCrO4).' This is a notorious adulterant of spices used to artificially bolster their color and weight. But the finding does hint at the possible motivation behind the tragic poisonings. There is no antidote for chromium exposure, and the Centers for Disease Control and Prevention recommends supportive care.
