If you wanted to actually parallel the argument it would be more like "the toxins in blue cheese magically don't affect the body if you get them from blue cheese even if they can through other exposure" since that's essentially the belief you're laying at this rotten cheese shit thanks to a throwaway line from a wikipedia saying "but no cases have been linked to the cheese" like it is the authority on infectious disease
Unless living in the cheese somehow alters the maggots in such a way that they can't survive your stomach and cause pseudomyiasis then, guess what? It can still happen just the same as if you consumed the maggots any other way! Unless you've got a proposed mechanism for why that wouldn't be the case other than "the wikipedia on rotten cheese said so"
