The death of a baby a month ago in a public hospital was caused mainly by rotting in food preparations, and the final number of infants killed in the tragedy that shook Tunisia's public was 14, a commission of inquiry said on Thursday.

"Fourteen babies died between 6 and 15 March in the maternity ward of the Association Hospital, not 15, as previously announced," the head of the investigation committee, Mohammed al-Douaaji, told a news conference devoted to presenting the findings.

Al-Duaji said the death was caused by bacterial rot in preparation of food preparations between March 4 and 8.

"There are multiple failures in the bag making room," he said. "There are several maintenance problems, lack of surveillance and disrespect for sterilization rules."

The investigation also found that "used bags carry bacteria passing through the hand," in addition to other reasons related to "the absence of training and training of the agents."

Former Minister of Health Abdel Raouf Sharif resigned after the incident that shook Tunisian public opinion, and was soon accepted by the Prime Minister Youssef the witness, who promised to "hold every failure if proven," and recently dismissed a number of senior officials in the ministry.
