Like the cell in which this nucleus is contained. Conclusion: It is impossible to get infected with infectious diseases through food.

Corrected by Penny. Did you learn well in school? No is? It is visible. Those relatively few bacteria (relatively to the total number of pathogens) that infect through food, have a very specific cell wall - the same "protective scapander", invulnerable to stomach acid and intestinal enzymes.
With enteroviruses even more fun, their capsule is assembled from several tightly interwoven proteins in the structure of alia diamond. Denaturate with acid or cut an enzyme in the small intestine this dense structure does not come out. the task is tougher disruption of headphones.something similar with hepatitis.
And these relatively few pathogens have spent about three billion years evolving, Carl, to survive in an aggressive environment.
Fruits and vegetables and fish meat have a much more modest history of evolution.
