Remember the old dacoit joke? When children refused to go to bed at night, weary mothers would scare them, “Doodh pi ke so jao, nahin to Gabbar aa jayega” (Have your milk and go to sleep, otherwise Gabbar will be here). The joke may be stale by now but in Madhya Pradesh’s Chambal region, once the den of dreaded dacoits like Gabbar Singh, there is a new, scary story brewing around milk and dairy products. Chambal is now a breeding ground for illegally-operated diaries that produce artificial and potentially life-threatening milk-based products.
