@DrYuriMom life, liberty, and property. Undue deprivation of any of these should be investigated. Almost any valid crime is some combination of these matters.
In the case of lying about ingredients, I don't think requiring more open information stifles competition, I believe that creates a more liberal and consentual arrangement between buyer and seller. Hence why fraud is fraud.
If someone knowingly puts antifreeze in cough medicine after deaths have occurred, there's an argument to consider that murder. If the matter was not researched ahead of time, that's neglectful homicide. In cases of medicine, there should absolutely be a standard of research expected. My issue is with the protectionism Big Pharma partakes in. That drives prices and kills people, too, when groups like Bayer/Monsanto are able to directly influence the body that regulates the food and medical industries.
Further reading, your arguments seem to lean towards acknowledge of some sort of corporate form of thought crime. Even with our current protectionist model, we still have phen-phens and the like.
