Tell me about dairy farmers

The addition of melamine in milk is done by dairy manufacturers. Dairy farmers sell non-toxic fresh milk to dairy manufacturers. These profiteers make liquid milk by adding water or adding other ingredients. What kind of powder is used to make baby milk powder? As a result, the finished product does not contain enough nitrogen and cannot pass the test, so melamine is added. The dairy farmers are innocent, but no one buys the finished milk, and of course fresh milk manufacturers will not enter the market, thus causing harm to these dairy farmers.
