No, there’s no inherent risk of sickness for snakes or crocodiles when consuming their prey whole. They have evolved to have this unique ability. Snakes, as well as all other snake species, are anatomically designed to eat their prey in its entirety. Their stomachs contain highly potent acids that effectively dissolve everything they ingest. As a result, the excrement produced by snakes resembles a white liquid, akin to bird droppings. Similarly, crocodiles also possess the capability to swallow their prey whole, as they have adapted to do so.
