Some meats from factory farming are contaminated and people got sick. The feed given to the animals is chalk full of antibiotics, heavy metals, disease-causing bacteria, and even bits of dead rodents, that are meant to keep the animals from getting sick and to increase growth according to Consumers Union (the policy and action arm of the nonprofit that publishes Consumer Reports). This practice has backfired because there are more diseases becoming immune to antibiotics. If the diseases are immune, they will become much tougher to treat effectively. According the Centers for Disease Control and Prevention, animal products are the primary source of saturated fat in the American diet. Saturated fat has been linked to heart disease and obesity.
