The students were supplied with seven cases of expired milk in November, Liang said, adding that she reported the incident to the county's education bureau but was ignored.
A school colleague of Liang, surnamed Wang, said that most of the 114 students in the school are from poor families whose parents are migrant workers in remote cities, and the children were left to their grandparents in the village.
"Most of the students' grandparents are illiterate, and they simply think it's a good thing that the children could have free lunches," Wang said.
Deng Fei, a renowned micro-blogger and also the initiator of a charity project that offers free lunches to rural schoolchildren, said that the government's fund for children's lunches used to be embezzled in many places.
"It will be good enough if the students could get 2 yuan of lunch from the 3-yuan standard program," he told the news website under People's Daily on Tuesday. "Some people made a profit from that."
