What do you think would happen if they actually put asbestos on the label?
Not everyone reads the label, but enough people do that it would be discovered on the first day, if not before the first day as some retailers check for label changes before putting a modified product on their shelves. Any retailer who didn't notice this to begin with would then notice the front page story condemning the company for doing it and all of the products would be removed from the shelves and returned to the manufacturer to save the retailer from the reputation hit of carrying it in their store. The manufacturer's reputation would be destroyed and no one would be willing to carry their products, depriving them of the incentive to do this because it would immediately tank the company, and this would be an obvious outcome to private equity firms who want to make rather than lose money.
Notice that you can currently buy things like arsenic for use as rat poison and this is not a problem because the label tells you that it's arsenic so you know not to use it as a food additive.
