On October 26, 2015, the World Health Organization concluded that eating processed red meats such as ham, bacon and sausages and highly processed meats such as hot dogs raises the risk of colon cancer. The research unit now classifies processed meats as "carcinogenic to humans". Overall red meat consumption in America has been falling for decades although meat consumption in America overall has stayed relatively the same since the 1970s. However due to new diets and lifestyles, Americans are scrutinizing what they consumer now more than ever. Combined with this scrutiny, the WHO's announcement will likely result in a continuing, if slight decline in retail volume of processed red meat.
