There is no best type of poison for putting in people's food in terms of it not being detectable as there are many different types of poisons and many variables that would need to be taken into consideration. Factors such as the amount of poison used, the age and health of the victim, the type of food or drink it was put in, and the environment where the poisoning occurred would all determine whether or not the poison would be detectable.
