Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep. [2]
TSEs in non-human mammals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle – popularly known as "mad cow disease" – and chronic wasting disease (CWD) in deer and elk. The variant form of Creutzfeldt–Jakob disease in humans is caused by exposure to bovine spongiform encephalopathy prions. [4] [5] [6]
Found in deer in northern Colorado and southern Wyoming in the 1990s, chronic wasting disease (CWD) has been recorded in free-ranging deer, elk and moose in at least 32 states across all parts of ...
The importance of ecopharmacovigilance is to monitor adverse effects of pharmaceuticals on humans through environmental exposure. [citation needed] Due to this relatively new field of science, researchers are continuously developing and understanding the impacts of pharmaceuticals in the environment and its risk on human and animal exposure ...
Due to small differences in PrP between different species it is unusual for a prion disease to transmit from one species to another. The human prion disease variant Creutzfeldt–Jakob disease, however, is thought to be caused by a prion that typically infects cattle, causing bovine spongiform encephalopathy and is transmitted through infected ...
Resistant bacteria in food can cause infections in humans. Similar to humans, giving antibiotics to food animals will kill most bacteria, but resistant bacteria can survive. When food animals are slaughtered and processed, resistant germs in the animal gut can contaminate the meat or other animal products.
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
