Growing concern over school milk program

Two tests, two results
Mengniu breathed a corporate sigh of relief at the test report, but food safety experts didn't let it go easily.
"Why do accidents always happen at branch plants?" said Sang Liwei, a food-safety lawyer in Beijing and a representative of the Global Food Safety Forum, a non-governmental organization.
The milk the Yulin children drank was processed at a local plant in Baoji that is owned by Inner Mongolia-based Mengniu. "One month ago," Sang said, "milk withdrawn from circulation was also produced by a subsidiary plant", that one in Zhengzhou, Henan province, and owned by Shanghai Bright Dairy & Food.
Mengniu was involved in two milk incidents in Shaanxi province within the past year, but test results for both set it free. Experts called for a new test by higher authorities.
Sang mentioned safety concerns at Nongfu Spring in Haikou, Hainan province, in 2009. Haikou Municipal Industrial and Commercial Bureau detected excessive mercury in the drinking water, but a later test by the provincial bureau showed the water met standards.
"No matter what happened behind the scenes, it at least showed that two tests can give different answers," Sang said.
Food safety experts said if the questioned milk indeed passed the tests, then the standard for dairy products in China is doubtful.
"We have two tests: qualitative and quantitative," Sang said. "Sanlu's baby formula had also been qualified before 2008, because there wasn't a test target for melamine," Sang said.
An estimated 300,000 infants, including six who died from kidney stones or other kidney damage, became victims of baby formula produced by Sanlu Group Co in 2008. The chemical melamine, which was added to the milk, caused it to appear to have a higher protein content.
So what really caused the Yulin schoolchildren to become ill?
Hours after the test results were announced, Mengniu suggested two possible reasons - the "unscientific" way the children drank the milk and hysteria, because "only 16 students vomited and felt nausea at first".
"After drinking the cold milk on an empty belly, some students experienced upper abdominal pain, nausea, vomiting and other symptoms of gastritis," said Zhao Yuanhua, vice-president of Mengniu Dairy Group.
Parents were skeptical. "Is this blaming the children's poor physical condition? Could it be said that hundreds of students are all in poor condition?" Chen, parent of a third-grader, was quoted by the Beijing News as saying.
Zhao told China Daily there are other reasons to believe the milk was safe. "Students at another primary school in Hanzhong, Shaanxi province, drank 700 cartons of milk from the same batch, but none experienced discomfort."
Zhao said teachers at the Yulin school have said the symptoms appeared first among 16 students and then seemed to spread. "That might be caused by hysteria," he said.
Mental health experts said it can happen. "If several children began to vomit and have stomachaches, it's possible that hundreds of others may be influenced . . . and undergo a collective reaction," said Ji Xuesong, a professor at Peking University's institute of mental health.
"If some students showed symptoms like nausea and vomiting, a teacher should avoid asking if others have the same feelings," Zhao said. "Asking that may make more children get infected."
