Nursery owner in China jailed for life after hundreds of children poisoned

Heshi Peixin Kindergarten in Tianshui, Gansu province, served food containing toxic lead. In July 2025, 247 pupils and staff were found to have abnormally high blood lead levels. The case matters because meals intended for young children were deliberately contaminated inside a nursery, where families expected basic safety.

Investigators found that chefs used inedible paint to improve the appearance of meals and attract more students. The paint was clearly marked as inedible. Lead-tainted steamed red date cakes and sausage corn buns were linked to the poisoning. Their lead levels were thousands of times above China’s food-safety limit.

Owner Li Huifang was sentenced to life in prison and lost 500,000 yuan in personal assets. Executive principal Zhi Jinglin received 15 years and a fine. Four kitchen staff members received six to eight years. Officials later introduced stricter campus-meal rules, including testing every new food batch.

The poisoning affected 247 pupils and staff at Heshi Peixin Kindergarten, according to the July 2025 findings. The article does not provide a separate breakdown showing exactly how many were children and how many were staff. It does state that 235 children from the nursery were treated for lead poisoning after eating contaminated food.

The food contamination was extreme. Red date cakes contained 1,052 milligrams of lead per kilogram, while sausage corn buns contained 1,340 milligrams per kilogram. China’s national food-safety limit was 0.5 milligrams per kilogram. That means the measured amounts were about 2,104 and 2,680 times the limit, respectively.

The article summarizes the overall contamination as lead levels 2,000 times above the national limit. The scale explains why the incident triggered a criminal investigation, prosecutions, and new national rules requiring every new food batch to be tested.

Lead poisoning is illness caused by harmful exposure to lead. The metal can enter the body through contaminated food, as happened at Heshi Peixin Kindergarten. It matters especially in early childhood because young children’s brains and nervous systems are still developing. The World Health Organization describes lead poisoning as particularly harmful to young children.

At the nursery, children ate steamed red date cakes and sausage corn buns containing very high lead levels. Lead in those foods was absorbed after eating and produced abnormally high blood lead levels. The article reports that 235 children needed treatment, showing that the exposure was medically serious rather than merely a laboratory finding.

The WHO says lead poisoning can severely damage the brain and central nervous system. The article does not list every possible symptom or outcome. However, the extreme contamination, large number of affected children, and need for treatment show why preventing lead from entering children’s meals is essential.

Inedible paint entered the nursery’s food because chefs used it to enhance the meals’ appearance. The reported purpose was to attract more students. This was not an accidental mix-up: investigators found that the paint was clearly marked as inedible, yet it was still used in food preparation.

The contaminated dishes included steamed red date cakes and sausage corn buns. Their lead levels reached 1,052 and 1,340 milligrams per kilogram. The court found that nursery owner Li Huifang and executive principal Zhi Jinglin instructed four kitchen staff members to add toxic and harmful ingredients to food served to children and staff.

The four kitchen workers carried out the practice and were sentenced to between six and eight years in prison. Li received a life sentence, while Zhi received 15 years. The case shows how unsafe instructions from senior people can turn routine meal preparation into a serious public-health danger.

Very high lead exposure can cause immediate illness and require medical treatment. In this case, 235 children were treated for lead poisoning after eating contaminated nursery food. The article does not specify their individual short-term symptoms, so those should not be assumed. Their treatment and abnormal blood tests confirm that the exposure had an urgent health impact.

The longer-term concern is injury to developing body systems. The World Health Organization says lead poisoning can severely damage the brain and central nervous system, and is particularly harmful to young children. Because the contaminated food contained up to 1,340 milligrams of lead per kilogram, the risk was far beyond ordinary background exposure.

The article does not state which children suffered permanent damage or describe later outcomes. It does show why early detection matters: blood tests identified abnormal lead levels, and affected children received treatment. Preventing contamination remains more reliable than trying to repair serious neurological harm afterward.

Food-safety safeguards work by creating checks at several points before meals are served. China’s new campus-meal guidelines require every new batch of food to be tested. They also require flour, rice, and cooking oil to come from centralised procurement points. These measures matter because they make ingredients easier to track and inspect.

Testing each batch could identify lead or other toxic substances before food reaches pupils. Controlled purchasing could reduce the chance that staff obtain unsafe or mislabelled materials. In the nursery case, inedible paint was used to improve food’s appearance, despite its warning label. Strong receiving checks and laboratory testing could help expose such contamination earlier.

Safeguards also need responsible staff and oversight. The article reports that officials and hospital staff later tried to cover up the incident by tampering with blood tests and accepting bribes. Therefore, procurement rules and batch testing should be supported by honest records, independent checks, and penalties for bypassing safety procedures.

Food-safety limits define how much of a hazardous substance is legally acceptable in food. They give inspectors and laboratories a fixed benchmark. At Heshi Peixin, the limit for lead was 0.5 milligrams per kilogram. The measured levels in two foods were vastly higher, making the danger clear.

Laboratory testing then turns that rule into evidence. Food samples showed lead levels of 1,052 and 1,340 milligrams per kilogram. Health checks provide a separate safeguard by testing people who may have been exposed. Blood tests found abnormally high lead levels in 247 pupils and staff, while 235 children received treatment.

These systems work best when they are independent and records cannot be altered. The article reports that officials and hospital staff tried to tamper with blood tests and accept bribes. Independent laboratories, transparent reporting, and outside medical review can help prevent such interference and trigger action sooner.
