Procedures and ingredients quality are not respected in counterfeit products (for example it's acceptable, in the us, for grated parmesan to have cellulose/wood pulp in it) and they still sell you the stuff at a high price.
i don't think anyone died because of these products but if you take fake parmigiano it's a $2B market.
