It explains that blood contains high levels of toxic uric acid, so the prescribed Islamic method of animal slaughter causes the animal to bleed out fully to avoid contaminated flesh. It also notes that pigs have difficulty being slaughtered in the prescribed neck-cutting way due to anatomical reasons, and their bodies do not effectively excrete uric acid like other animals, posing health risks.
