In fact, the measure has already been implemented in Delhi and Andhra Pradesh and results are awaited of the first samples collected in the two states.
Scientists from CSIR would be involved in the exercise which will be undertaken across the country, HRD Ministry officials said.
The outcome of the reports from the tests would have a bearing on the funds released to the states, they said.
The recent midday-meal tragedy in Bihar claimed the lives of 23 students after they consumed food served in their school.
The latest development follows strong instructions from HRD Ministry to the states to strictly adhere to the guidelines drawn up to ensure safety of the food served as part of the scheme.
Among the HRD Ministry directions is one calling for teachers and a member of the school management committee to taste the food before it is served to the children.
Reports suggest that the ministry has received over 100 complaints over the last two years about mismanagement in the mid-day meal scheme and misappropriation of funds, notably in the states of Uttar Pradesh, Bihar, Madhya Pradesh and West Bengal.
