Lead exposure is toxic even at low levels, resulting in impairments that can affect a child's lifelong success. In North Carolina, testing for lead is encouraged for all children at ages 1 and 2 years and required for children covered by Medicaid; investigations are performed to identify potential exposure sources for children with blood lead levels (BLLs) ≥5 μg/dL. During June-August 2023, routine lead testing identified four asymptomatic North Carolina children with BLLs ≥5 μg/dL. Home investigations identified only WanaBana brand apple cinnamon fruit puree pouches as a potential exposure source; product samples contained 1.9-3.0 ppm of lead. An expanded nationwide investigation led to identification of approximately 500 cases of childhood lead exposure believed to be linked to consumption of apple cinnamon purees, including 22 cases in North Carolina. Fewer than one half (45%) of the 22 North Carolina cases were among children covered by Medicaid. A coordinated multiagency communication strategy was implemented in North Carolina to notify consumers of the hazard and provide recommendations for preventing further exposure. The Food and Drug Administration issued a nationwide public health advisory on October 28, 2023; 2 days later, the manufacturer issued a voluntary recall. Routine testing of young children for lead exposure, combined with thorough environmental investigations, can identify emerging sources of lead exposure and limit further harm.
铅暴露即使在低水平下也是有毒的,会导致损害,从而影响儿童一生的成功。在北卡罗来纳州,建议对所有 1 岁和 2 岁的儿童进行铅检测,对参加医疗补助计划的儿童则要求进行检测;对于血铅水平(BLL)≥5μg/dL 的儿童,会进行调查以确定潜在的暴露源。在 2023 年 6 月至 8 月期间,常规铅检测发现了 4 名无症状的北卡罗来纳州儿童的 BLL≥5μg/dL。家庭调查仅发现 WanaBana 牌苹果肉桂水果泥袋是潜在的暴露源;产品样本中含有 1.9-3.0ppm 的铅。一项全国范围的扩大调查导致发现了大约 500 例儿童铅暴露病例,据信这些病例与食用苹果肉桂泥有关,其中包括北卡罗来纳州的 22 例。在这 22 例北卡罗来纳州病例中,不到一半(45%)是参加医疗补助计划的儿童。北卡罗来纳州实施了一项协调的多机构沟通策略,以通知消费者危险情况,并提供预防进一步暴露的建议。美国食品和药物管理局于 2023 年 10 月 28 日发布了全国公共卫生咨询;两天后,制造商发布了自愿召回。对幼儿进行常规的铅暴露检测,结合彻底的环境调查,可以发现新的铅暴露源,并限制进一步的伤害。
