Final answer:
The two common food-borne viruses that contaminate food through fecal contamination are Norovirus and Hepatitis A. These viruses can cause significant gastrointestinal and liver inflammation, respectively.
Step-by-step explanation:
The two common food-borne viruses that typically contaminate our food supply through fecal-contaminated waters and food are Norovirus and Hepatitis A.
Norovirus is known for causing inflammation of the stomach and intestines and has been notorious for recent outbreaks on cruise ships. Hepatitis A, on the other hand, leads to inflammation of the liver and is treated primarily through rest and diet changes.
These viruses can enter our food supply when water contaminated with human waste is used in food production, or when infected food handlers don't follow proper hygiene practices, such as thoroughly washing their hands after using the bathroom.
