Mr. Sharma added, “Let Railway do its investigation, we can’t rely on it. We will do our bit. I have informed my team to do one more round of research on food served in trains. In a month’s time, we will have a detailed report ready which will capture the total loss to exchequer because of this. I have instructed my team to have their stomach fool when they are testing the railway food, keep their mouth covered, by mistake also they should not eat even one spoon”.
