Pink Slime in School Burgers

As most of you have probably already heard, many meat packing companies mix their meat with a man made, artificial ingredient known as "pink slime". The USDA has allowed for companies to use pink slime in their products, and for years it has been sold in grocery stores and served in schools. Recently, because of the publicity of the pink slime, the USDA said that schools can pick whether they want to serve that type of meat or not.
This news really bugged me, what other disgusting ingredients are there in the food I am eating? It is so upsetting that the USDA, which is supposed to regulate what goes into our food, allows all of these nasty ingredients. This is just meat, who knows what we will come to know next. I think the USDA should start getting regulated.
