Eating raw fish isn't just about the absence of fire; it’s about :
Freshwater fish are generally off-limits raw due to high risks of tapeworms and flukes. Saltwater fish are safer but not immune. This is why "Sushi Grade" is a vital distinction—it usually implies the fish was flash-frozen at ultra-low temperatures (-31°F or below) to kill parasites while maintaining cell structure.
In ceviche , the citric acid from limes "cooks" the fish by denaturing the proteins, changing the flesh from translucent to opaque without heat.
Without heat to kill microbes like Salmonella or Vibrio vulnificus , the safety of the dish relies entirely on the cold chain —the unbroken line of refrigeration from the moment the fish leaves the water to the moment it hits your plate. The Alchemy of Preparation
