More than 1,700 Indonesian students and teachers sickened this week due to free meals programme

LASEM, Indonesia, Sept 3 (Reuters) - Another 777 students and teachers contracted food poisoning in Indonesia's Central Java after consuming government-issued free meals, a school principal said on Thursday, bringing the total number of people made ill by the scheme to more than 1,700 in just a week.

In separate incidents in three other locations this week, 950 Indonesians had fallen ill as a result of food poisoning linked to the programme, a member of a parliamentary commission overseeing health said.

President Prabowo Subianto launched the multibillion-dollar free meal programme last year to improve nutrition for tens of millions of children, but the costly scheme has been dogged by allegations of corruption, leadership changes and a spate of mass food poisoning outbreaks.

In a senior high school in Lasem, Central Java, 752 students and 25 teachers have been suffering from diarrhoea and vomiting after consuming free meals on Wednesday, said the school's principal, Juhartutik.

The students in Lasem were given grilled chicken. Before it was distributed, a food taster found that some of it was "slimy", Juhartutik said.

"The slimy ones had already been set aside... The kitchen operator said the food was cooked at 3 a.m. and it was eaten at noon," she said, adding that most of the victims were sent home.

Joko Paryanto, a local doctor who treated the victims, said 15 students and teachers have been hospitalised.

On Tuesday, 664 students fell ill in Sidoarjo, East Java, said Herawati Yuwantina, a local official.

In two other cases on Wednesday, 49 people in the East Java city of Nganjuk and 237 in the West Sumatra region of Agam contracted food poisoning, said Charles Honoris, a lawmaker and member of the sole political party outside the governing coalition, citing local health department data.

Charles wrote on Instagram that they were not isolated incidents.

"This is a failure of the system," he said.

The National Nutrition Agency, which oversees the $12.94 billion programme, did not immediately respond to a request for comment on the food poisoning cases. It suspended the kitchen linked to the Sidoarjo case on Wednesday.

As of September 1, 50,000 individuals had been affected by food poisoning cases, Charles said, citing health department data.

Improper food storage and late delivery of cooked meals are often to blame for the food poisoning.

In July, a survey by pollster Saiful Mujani Research and Consulting showed only one-third of people were satisfied with the scheme, with poisoning cases cited as a major reason.
