It's pretty self evident isn't it. Having some (likely small) percentage of people getting food that they shouldn't will likely only have very minor influence on how muchnfood can be distributed (often enough there are some left overs even). Denying someone who really needs the food, might mean that person will not have food possible for several days. That's a pretty big cost for the person.
Generally many "fraud prevention methods" for poor people are more about punishing poor people than actual fraud prevention. Often the cost of enforcement is as high or higher than the cost of the fraud.
