Unlike bacteria and viruses, prions are not living organisms, which explains why they are not destroyed by normal cooking temperatures. These infectious proteins possess an extraordinary resistance to heat and conventional sterilization methods, a critical fact for understanding food safety.

While most forms of human prion disease occur spontaneously or are hereditary, one specific type, variant Creutzfeldt-Jakob disease (vCJD), has been linked to eating meat contaminated with Bovine Spongiform Encephalopathy (BSE). This connection first gained widespread attention during the 'mad cow disease' outbreak in the UK in the 1990s, raising serious food safety concerns. However, thanks to rigorous international regulations, the risk of contracting a prion disease from meat is now extremely low.

A single pufferfish contains enough tetrodotoxin to kill 30 humans, making its consumption extremely risky. But beyond such famously dangerous delicacies, is there any meat humans can't eat that isn't a prepared specialty or a result of improper handling?

The human body's largest organ, the skin, is composed of water, protein, fats, and minerals. But is human skin nutritious? While it contains some basic biological components, consuming it presents severe health risks, making it unsuitable and dangerous as a food source.

In 1897, a group of Arctic explorers tragically learned that polar bear liver is highly toxic, causing severe illness due to excessive Vitamin A. This incident highlights a crucial survival and culinary lesson: not all parts of an animal are safe to consume, begging the question, 'what parts of an animal are not safe to eat?'

According to a study reported by the CDC, consuming meat from BSE-infected cows has been linked to variant Creutzfeldt-Jakob disease (vCJD) in humans, highlighting that certain animal products are dangerous. While humans have a diverse diet, a number of meats and animal parts, including specific organs, carry toxins, pathogens, or other dangers that make them unsafe to eat.

According to the Centers for Disease Control and Prevention, prions cannot be destroyed by standard cooking methods, including boiling, frying, or radiation. This means that simply cooking meat does not prevent mad cow disease, also known as Bovine Spongiform Encephalopathy (BSE).

While prion diseases like 'mad cow' are notoriously fatal in mammals, extensive scientific research has confirmed that salmon do not have prions, specifically the infectious form that causes these neurodegenerative illnesses. Fears about prions in seafood, though understandable given their resistance, are largely unfounded due to significant biological species barriers.
