Core Viewpoint - The investigation into the abnormal blood lead levels among children at the Gansu Province's Maiji District Banshi Peixin Kindergarten revealed serious food safety violations, including the use of toxic non-food-grade pigments in food preparation, leading to significant health risks for the children involved [1][2][3]. Group 1: Case Investigation - The kindergarten's chef purchased non-food-grade pigments online, with lead content in the pigments significantly exceeding safety standards, leading to food items served to children containing lead levels as high as 1340 mg/kg [2][3]. - The kindergarten's principal directed the use of these pigments to enhance food appearance, despite knowing the risks, resulting in multiple children exhibiting abnormal blood lead levels [3][5]. - Six individuals, including the principal and chefs, have been arrested for their involvement in producing toxic food [4][5]. Group 2: Environmental Pollution Investigation - Environmental tests around the kindergarten showed no lead contamination in air, water, or soil, indicating that the source of lead exposure was not from the surrounding environment [6][7][8]. - Historical analysis of the area confirmed that prior land use did not involve lead-related activities, further supporting the conclusion that the kindergarten's practices were the primary cause of lead exposure [7][9]. Group 3: Blood Lead Testing and Data Integrity - A total of 267 blood samples from children and staff were tested, revealing multiple instances of abnormal lead levels, with some results later modified, raising concerns about the integrity of the testing process [14][16]. - The Gansu Provincial Center for Disease Control's testing procedures were found to be flawed, leading to inaccurate results due to improper sample handling [16]. Group 4: Accountability and Consequences - Investigations have led to 17 individuals being subjected to disciplinary actions, including officials from the local education and health departments for negligence and corruption related to the kindergarten's operations [19][20]. - The provincial government has committed to a thorough investigation and accountability measures against all involved parties, emphasizing a zero-tolerance policy towards such violations [24]. Group 5: Medical Response and Treatment - All children and staff at the kindergarten underwent blood lead testing, with a significant number showing elevated levels, prompting immediate medical intervention [21][22]. - A coordinated medical response has been established, with treatment protocols in place for affected individuals, and ongoing monitoring to ensure recovery and health management [23].
