In its effort to verify whether districts that have achieved Open Defecation Free (ODF) status are actually sustaining it, about 50,000 people will receive pre-recorded calls from Bachchan in the next week or 10 days.
The number that will receive such calls will be selected randomly from ODF districts. Till now 91 districts and nearly 1.58 lakh villages have achieved ODF status.
Those selected numbers will first get an SMS informing them about the calling of Amitabh Bachchan in advance.
After the introduction Megastar will ask the questions as whether anyone of the receiver's family practice open defection and the other about other villagers.
Receivers will have two options press 1 for 'yes' and 2 for 'No'.
Officials said while toilet coverage has increased substantially from nearly 48% to 61% since Swachh Bharat Mission was launched, poor toilet coverage in Uttar Pradesh and Bihar is a cause of concern.
