Food Safety

For my research paper my topic requires finding out what are some saftey problems with the food system.  I would like to look into all the sanitation problems in factories and the way the animals are taken care of regarding their feeding and treatment. Furthermore I would like to find out about the chemicals put into our plants to make them grow out of season as well as bigger and faster. Not only are the outcomes of the food system affecting us but also the environment. There is so many problems with the way our food is really made and I would like to look into that.
